I`m calling this robot basics, but I`m leaning to more like a minimum "robot."

Introduce a couple motors, a switch, and some bumpers.

Add some delays, etc by using a timer control. Thus it can crawl backwards for example, for 1/2 second then start going forward again. Then you can power on a right or left turn on going forward.

If you put a listing and it leaves out some, then you have exceeded the limits for an input box and you will need to split...

There`s a bug. If you use pre for format control, the pre shows in the listing for the project. For now, skip the insertion of the <pre>uses direct format</pre>.

What is a robot?

Many things, but for this intro it will be anything that moves around fairly autonomously. That leaves us wide open for lots of potential applications we would call robot. So we would focus it by adding it should perform some desired function.

Now we have something to use for a philosophy to guide the development of the robot into something we can BUILD!

Our robot will have to have it's own method of propulsion. Legs, wheels, something to let it move around in our designated area. Different applications would require different mobility approaches. It could move by flying on the one hand. But just to keep it kind of uniform and mainly cheap, we'll specify it has to move around a room. With carpet and potentially rugs.

Still, it could use legs. Let's see, for every leg joint I would have to use several methods for powering the leg and providing enough degrees of freedom to make the leg walk. Then multiply by Four, or possibly three or two. Hmmm. Too steep for me.

How about 3 dollar electric motors at every joint, or cheaper, thus better still. Spend a bit more on motors and only use two of em to provide locomotion! Brilliant, how can we do it? How about a wheel?

Hmmm, get the cheap motor some gears and use 2 to 4 motors and you have all kinds of locomotion potential.

Show square-wheeled bot. Talk about gears and the gear motor... How you experimented with even the walking spokes. How Robo Quad uses offset regular rotating motors to achieve it's walk.

Point to Quadraped using servos, stuff like that...

Show electrical circuit and motor... Schematic of Buggy Bot...

Show how circuit or transmission can move forward or backwards I think... Maybe I don't need this???
