Let's Make Robots!

Rocket Brand Robot Test Facility

Dog-hair-free Robot Testing Area


I have removed robot wheels to remove dog hair one too many times...

This is my new test facility. Built from a 4x8 sheet of whiteboard material and some cheap #2 pine, the basic frame went together pretty quick with nothing more than simple, basic construction techniques. The lift mechanism is (2) window motors from a Hyundai Elantra. --I have to recommend these motors, they are awesome! Super powerful with a nice big gear exposed to weld to, and they even come in left and right models. Not to mention, they only draw a few amps each. The switches are just center-off, DPDT momentary guys from the store of which we do not speak (Shady 'o Rack). A 7.2v racing pack provides the power.

The steel work was pretty simple but a little time consuming, done with just an angle grinder and a drill press -nothing fancy. All-in-all, it took me a few hours one night to build the frame and most of the next afternoon to do the metal work. I think I spent around 100 bucks or so on the whole thing.

Lower and retract work flawlessly with the exception of one motor working just slightly faster than the other --I added a second switch to allow the motors to be switched independently and now all is right in the world.

I've seen gaming tables of this size using the same method of ceiling storage. I never would have applied it to robotics. Brilliant.

Great minds think alike, look what I did, just last weekend:

(It didn't fly like yours though ;D) And in fact, I did not even make it, I only marked it up with tape. It was for a show I did in Norway:


But I envy you - a good track like that is priceless to have ready! (Without dog hair :)

Nice one, Chris :)

Wow, that board is awesome.

Is it actually robot-based Pacman? It looks like you got your ghosts there plus a couple "regular" bots. Bunch of kids around too --is it all RC? Whatever it is, it is great!


2 robots semi RC; Chose if they should go left/right when facing a wall. Controller for each had 2 flashing lights, and two buttons. Robots had a light in either side, matching those on controller, indicating what side the robots would turn to. If you managed to drive a "pacman" robot over a "power up" (silver markings on the track, with magnets to sense under neath), a large needle would tilt downwards, and point ahead for a while.

3 "Ghosts"; Driving around with baloons on top. If a "pacman" managed to drive over a "power up", so the needle pointed ahead, it could try and pop a baloon. A pop was detected, the robot drove out to a side to get a new baloon on, and the happy popper got himself a coke for a prize :)

Cool. You should post about your event, Frits!

Nice thought Chris! I probably need to build one myself too. Running out of space soon!!!!

Lol what chris.

Because, I was thinking of doing something similar if I ever got rich and could open a shop that could host sumo comps or whatnot.

SNAZZY, I think you should make your phone and robot able to control it.  It might also be a good place to store a swarm of robots!
