It's more research into building my upright RFL Football Robot! So far things are working pretty well, but I've got to work the pc board into the design, plus build a Cage around my bot, just in case I have to do battle.
Anyway, that got me thinking about wire as a base for the kinds of little bots I build around here, and very applicable to the RFL Football Bot (see March, this blog)...

It looks like tying together rebar for pouring a cement foundation.

Eventually, you solder the wires, then clip the excess, the solder holds the structure together, the wires help create the structure...

The tabs have to be parallel to the axle, so you bend the wire appropriately...

Dropping in the battery pack, so the switch is accessible while the bot runs...

Notice how the servo is held by bending a square around it, then tucking a piece of wire firmly against the servo... This makes the servo have a slight angle, but it is very strong... As you can see in the next photo...

Motor controller with picAxe 14m and a brand new Toshiba 1 amp motor driver (with dynamic breaking built-in... This thing is sweeeeeet! It uses two pins from the microprocessor to control the four operational modes: forward, reverse, stop, and brake... Very nice indeed.

Soon (after the Pilot Test Run), I'd find out that it wouldn't steer because the front axle is fixed and what is transmitted to one wheel also goes to the other, this isn't good for making turns... In fact, with the batteries on the backend, there is som much weight I can't get the bot to steer at all...
The answer: Move the battery pack to shift the weight to the front wheels... as you can see in the next picture...

The new shape of the weekend project bot!

The side....
And, of course, like all good bot-builders and mashup dudes, here is the video: A step-by-step "weekend project" sure, it's about the wireframe idea for bot-bodies, but it's also all about this little Buggy-Bot...
Next stop for the Buggy Bot, get some sensors, so it can do object avoidance...
