This is the first beambot I’ve ever built.

I’m not sure it qualifies as a beambot, but it was built in a similar way.
It’s no engineering masterpiece, all it does is simply moving forward.

The whole machine is built around the battery socket. It’s super simple - there are two wheels glued to the bottom of the socket, and a motor in between, with axis pressed against one of them from side. Nothing too fancy or efficient, but does the trick.

There’s a capacitor in parallel to the motor, but it’s not important in this design. There’s no control logic that needs protecting here.

I’ve also added a switch on the back, so you can easily turn it off instead of removing the battery.
