Zombie Drives Wheelchair

You guessed it...  It's not really a ghost driving the wheelchair.  The wheelchair is Autonomous!  That's right, this wheelchair can take you on a tour of a rather large area...

Wheelchair Robot Becomes Autonomous

There's a new robot in town and it is finding it's way along my messy deck.
 

Check out the action and how-to build your own on CwhatIcanDo website.

This wheelchair is getting smarter.  Er, uh, this ROBOT is getting smarter.  And you can STILL use it as a wheelchair.   You will have to modify the software so you can turn it on and off, but imagine you could send it loose on a piece of land it would avoid collisions with farm animals and give an auto-tour of the property to the wheelchair rider!  :-)

Wireless RF Remote for Power Chair Twenty USD

The latest video on CwhatIcanDo.com.  This one is for people with power chairs who would like to be able to have wireless control over their wheelchairs.  This one can allow freedom to move your chair aside when you plop down in a favorite chair or visit with people at the table.  Just move the power chair aside under remote control.

This is about as simple as you can make a thing.  Once I established the presence of a 3 volt power source, I knew I could run the whole unit on 12 volts directly from the power chair.  (Remember in another project, we use an H-bridge to robotically control things?)

Robot From Power Chair Follows Wall

This time I wanted to continue to use the controller I already had and add sensors.  To test my ideas, I made a pretty simple wall follower type algorithm and that made it happen like this:

So now I can keep a robot on the straight and narrow using IR in close quarters.   I expect a sonar would also be nice, so I guess I will have to add a sonar ping'er and give that a try.

Next time, though, I'm really thinking about making something really practical for wheelchair owners.  Not that it isn't practical to manage a wheelchair through narrow passages, but that can come later.

Robot Made From Power Chair To Help Handicapped

I've been wanting to make a robot that could haul stuff around while I work around the garden, plus I wanted my grandkids to be able to ride on it.  In the best case, I WANTED to RIDE IT!

So I began pursuing old beat-up power wheelchairs.  Finally, my waiting and looking paid off and I obtained a relatively modern older power chair called the Mini Jazzy.  It could pull a 250 pound person up a 5% grade, so it should have no problem with a 60 pound grandchild or probably even a 160 pound grampa.  For a month or so, I underwent subtle humiliation when my wife would announce to friends that I had a wheelchair!  It's a Robot, I insisted having even taken off the chair. Finally, I could take it no longer so I decided to build out enough of a robot to put it into a controlled loop Forward, Backward, Left, Right, and Stop.  This is the first step to almost any robot project I've done.  I would have a robot!  No wheelchair for me.  

Follow the Link to the How-To build a robot from a power wheelchair on CwhatIcanDo.com.

Because of all the research I had to do (the web doesn't give up much help on this subject) I decided to make my goal a little bigger than just making a fun bot that doesn't do too much to help anyone, just to entertain myself.   So I decided I would make it so you could still control the wheelchair even with the robotic control.  Now a disabled person could bring the power chair to them from across the way.  

I could even put sensors on it so it could assist another person in ushering a handicapped person in a crowd, just like I discovered the Japanese doing.   In fact, I decided it would be more fun to create something that could help out handicapped people than to make an IED "sniffer".    It's more fun to make love than war.  So this project is what you might call my Robot Love Project...

Me and My Robots: Robot powered by Linux Has Onboard Camera

Me and My Robots: Robot powered by Linux Has Onboard Camera

Robot powered by Linux Has Onboard Camera

This looks like the real thing. Real enough. It's low-cost (darn-near cheap!) yet has a 2.4ghz Nordic radio, so the controller has a video screen from which you view the video camera on the robot itself. Yes, it's powered by Linux. Yes, there is a USB port which allows you to upload your own and other's programs.

And you can program the bot to run routes.

One pile of really really fun kid stuff!!! But around here, it's open to being hacked, modded, re-purposed and folded spindled and mutilated.



This is another C What I Can Do video at cWhatIcanDo.com, so take a look. C What I Can Do .com I have a feeling we will be back to this project, I've downloaded the software and have almost clean compiles of all the sample projects. I've downloaded speed control programs which allow you to tweak the PWM motor drivers... This is going to be some fun ripping into the little compact box. Let's hope it doesn't disappoint. It hasn't yet.

Build A Simple Black Box Robot

Build a Black Box Robot

Why a black Box? So I can "wrap it" in anything. I'm thinking about a stuffed animal head to make a little virtual(real?) pet.



Someday this may become the little dog robot I tried to build before (see dogBot). You can see the whole project on CwhatIcanDo.com, of course.

My New Novel

White Buffalo Herd

A successful writer is suffering confusion after his involvement with an American Indian group who are involved with mysticism, the occult and strange stuff goin' on all around him. This confusion leads him to corruption, attempted murder (his own) and an involvement with a mysterious woman who get's caught up in the mysteriousness as well.

By publishing on kindle anyone reading this blog can download a copy of the book for pc, mac, iphone, android, ipad, and of course, kindle... The price of WBH is $5.95 and I've been told it's a pretty good read.

If you wanna give it a try:

http://www.amazon.com/White-Buffalo-Herd-wbh-ebook/dp/B003TXS43U/ref=sr_1_1?ie=UTF8&m=AG56TWVU5XWC2&s=digital-text&qid=1279326029&sr=1-1

The sample download is free. You'll know if you are interested once you read the sample. I've got a Motorola Droid, the thing turned out pretty nice. I hope you like it, if enough people like it, I have others ready to follow. The next one has corporate intrigue and all sorts of entertaining shenanigans.

Cheap and Easy Robots

Here we go again. This time CwhatIcando.com has a continuation of my last project. This time, we secure the motor-control board and let our picAxe 08m drive our robot around. Note, we moved the IR detector to the optimum spot for avoiding floor objects. By using a little shim, we can move our beam up or down enough to make it avoid a carpet edge, or roll over anything but really big stuff:

Keep on having fun!!!

Four Dollar Rumble Bot Becomes Autonomous

I put this rumbleBot video up in response to all the Roboticists who are introducing the Arduino as autonmous controller. Here's an even cheaper way to make a cheapo bot.



Take a little motor controller board (15 bucks)
Deluxe model get a picAxe 08m (4 bucks)
Grab a Sharp IR unit (15 bucks)
Don't forget the Rumble-Bot (5 - 30 bucks - mine was $4 at second-hand store)

So for around $40 bucks, you get a pretty amazing robot. If you leave the head on and put little sensor switches in the bot's hands, you have a pretty decent looking little robot.

Of course, the whole project is on CwhatIcanDo.com...

Motorola Droid Can it Run a Robot?

Can you use a DROID, or other smartphone to operate a Robot directly? The ads infer that a Droid is better than other smart-phones, because you can reallly get stuff done with it. Basically, that is true. Without any apps, or only with free apps, you can still approach the phone as a programmer.

From Motorola Droid

Yes Virginia, it is possible to imagine driving a robot around using the Droid itself for most everything but driving the high current to the wheels.

This is an ongoing project started on CwhatIcanDo.com so someday, someone will figure out the process for sending messages back and forth from a robot base, like the i-robot Create. Check out the more in depth coverage of the project at C What I Can Do website.

Virtual Robot How-To

This is a robot! It's a virtual robot! You can play with it online.

Or, better still visit the How-To on CwhatIcanDo, where you can watch the video and look inside the Flash and ActionScript files to make your own, or modify the basic "unit". CwhatIcanDo



This is a how-to inspired by all the people who built variations on the robots I have constructed. The lightest weight robot "In the World"

And it's fun to play around with it: Play at Cybercritters.com

Have fun with this month's project!!!

May's Project Not A Robot???

The next new project...



I point out (again) this is not a Robot Project... Any blog followers understand that CwhatIcanDo is now taking on my projects. This one is something I put together in a non-robotic attempt to save myself from having to find and energize the "mute" function when I needed. Like when I answer the phone.

HOW-TO On C What I Can Do

The project was undertaken because I was frustrated with having to find the clicker to stop the assault on my senses by over modulated and over acted TV commercials. I confess I am addicted to the science and history channels, and the daily show and Colbert, all have commercials apparently compressed by our beloved local cable operation. Anyway, I thought it would be a good idea to make something I could just tap and the result would be "muting" the tv.

Implementation was easy, I used a picAxe chip (around four bucks) a little round universal PC board a button and an IR LED driver setup to send '20' code to my Sony TV so it would MUTE!

Making things wearable was a greater problem than originally anticipated (I'm no jeweler - as you'll notice), but I made something that would test the practicality of such a device. C What I Can Do provided a way to demonstrate the principle, and now to see if it would generate any interest, then I can think about another model.

cWhatIcanDo Website

A new video for CwhatIcando... It's an introduction to the website which I plan to promote during 2009.

Build a Tracked Drive Robot - How I built TrakBot

I got a comment on this blog a few days ago and I decided to take on the project someone suggested. While they thought the TrakBot was interesting, they wanted more of a "how-to" so they could build their own trakBot.

From TrakBot: Build Your Own Track Drive Robot

Since, as many of my readers know, I'm deeply involved in creating a new website which is all about "how-to" do things. How to put together a dual H-Bridge, to how to put together or mod a robot, or just about anything else.

I made the commitment! I would create an article for CwhatIcanDo.com about how to build the actual robot that I showed on this website. I really just talked about it and generalized about things like software, how it all worked and most of all, no schematic.

So I decided to make a project for CwhatIcanDo just to see how long it took and at the same time, to answer the comment on this blog.

The result lives Here This is the project broken out in a How-To complete with schematics and software on the CwhatIcanDo Alpha Website. It's not quite ready for a full Beta release, and doing this project just reminded me what I still have left to do. But, even so, I built a nice project. It took about 4 hours with a ton of interruptions. I think the time to create a project will get better in the future (before the site actually opens to the public) but I'm pretty excited about the outcome.

(Updated Nov 3, 2008): There are a couple of other work-around type bugs, but the point is, it can be done. And the results are pretty nice. But I'll let my blog questioner answer that. Does he believe he could build his own trakBot and learn a lot in the doing?

The current workaround, Nov 3, 2008 is simple: You'll have to supply your videos from your own YouTube or Google Video account, the software is not yet set up to allow you to upload videos and pictures from the Creator's Tools. Enjoy becoming an alpha tester!! But a lot of ppl have YouTube Accounts anyway. And, soon, the tools will all be implemented.

If you want to visit the website in Alpha Test (Release Candidate 1), you'll have to go "around" the main page, that doorway won't be open until the actual Beta Site release. We are shooting for "around Thanksgiving" to open the Beta Site.

Visit the Open Alpha Test at cWhatIcanDo.com/main/ Open for ppl who are guided there on my Blog (here) or other fairly private links on various Blogs as the site is "discovered"...

TriCycle Bot

Check this guy out.  Why build such a thing?  Because I want to create a Ball Bot.  That's right. This month I've been pondering making a ball robot. So I've been thinking about what and how to do it.  Here's where I went at first.  I figured a couple of wheels inside a ball wouldn't work unless one of the wheels allowed me to move in all directions.

So I figured, why not just one wheel?  Standing up would be a problem.  That was easy to fix, you just make a triangle.  Use a couple of wheels expressly to hold the rest of the bot, that's all.  The tricycle would exist inside a large round ball instead of moving around the floor.  The tricycle bot serves as kind of an experiment in "can you do it?"  The answer is, YES!  And the video is the proof.

So what's next?  Find a suitable ball to set the tricycle inside and see if the ball moves around.  Maybe next time I make an entry???

UPDATE on CwhatIcanDo.com:  

It's being used and we've had a couple of bugs. I'm glad it's only family and friends alpha!  On time for a Fall Beta, but that decision is still a month away.  This is another video featured on the CwhatIcanDo website.

RFL AI-01 Ultimate Football Machine

It's gotta be the Ultimate Football Machine to live up to the promise. And it does! I wish I could send you to the new CwhatIcanDo.com website to see the whole project. You can sneak a peek...



While you charge the batteries (getting ready for the full experience.) Put the extenders on your bot and it will surprise you just how well it will be able to stand up "around the house." My bumpy back deck is a favorite robot test area, as you know from all the videos. In the "out of the box" video above, you will see the bot in the raw, out of the box, so to speak. I recommend, unless you are putting one of these bots into a real RFL American Football Robot Game, put the extenders on. You have to charge the battery anyway, so you might as well start with the extenders, it will run better on carpets, in fact most bumpy surfaces around most houses.



This is one tough bot. I'm thinking it is a candidate for a really great bot body. It does everything I hoped DogBot would do, like climb the hill in front of my house. It can stop on a hill. It has enough power to last long enough for an hour's walk. Did I mention it is tough? Mega thick reinforced plastic frame parts can take a drop, and a hit from another robot. Now I'm rethinking that robot that I take on walks with me.

I played around with the upright robot base enough to appreciate the balance and power transfer to the wheels and all that. With the extenders, this baby could negotiate sidewalks and my back deck, it's still fairly light and easy to grab and haul up on the curb. So now it is the candidate for my own cyber pet...

Weekend Project L298 Dual H-Bridge

This is a dual H-bridge Motor Controller that delivers 4Amps total (2A / motor). The 293, the little brother of this controller, only handles an amp. This one doubles its capability. Since the pinout is a little strange, I bought the whole thing with a PC board from HVTech, or Solarbotics, no matter, they are all the same now.

Anyway, it went together in a blink. Alright, true, a long blink, say a couple of hours, but together it went and passed the operation test as soon as it was hooked up.

Next expect me to do something freaky with the Motor Driver...

I'm back to building robots N stuff again. Though I'm also finishing off CwhatIcanDo and nursing it through the Alpha Testing period. The bug list has gotten much smaller and the things to do list has shrunk to a manageable size.

The website is coming!!!!

How's The New Website Effort Going?

With a few bugs still left, but a manageable list, and no way yet to log into the website, alpha testing will none the less begin.

That's because Phase One of Alpha Testing is all internal. We, the developers will now begin to develop projects on CwhatIcanDo.com. Phase One testing will continue till mid-August when we will invite creators to participate in wringing out the final issues and making suggestions to make the site easy to use and understand.

After what we expect to be a month and one half of actual development using the site and the Creator Tools, we will open the website to the general public. Most likely this will be at the end of November, just in time for holiday web marketing pushes. Because CwhatIcanDo is not exactly a gift shop, we are not driven by retail deadlines, but we are also sure that with our "buy here" parts lists, we are going to stimulate purchasing of parts and tools to create another's version of the projects on CwhatIcanDo.

So this month's blog entry is not going to be very interesting until somewhere around the end of the month when I will redirect you via this blog to the new C What I Can Do website!

Whoopee! Almost There!!!!
