Let's Make Robots!

rc tracked giant robot

pull a small trailer or a car, climb hills, be unstopable and unbreakable

Hi, after building my 20Kg tracked robot, I would like to build the same kind of thing, but tougher. I would like to find tracks from a snowblower(I can't find a dealer that would send to France yet), motors and electrics from a wheelchair and strong chassis. It would be nice if it could run after it flips over.

Hi French man (ou plutot salut l'ami !)

Your work is awesome !

Very clean assembly and an amazing speed and manageability !

Well done dude !

Keep the good work !

MoX ( a French guy too)

Looking good!

Even with the reduced drive sprocket size, it looks like it has more speed than torque. It showed on the hills. Always a trade-off, of course.

Great project. Thanks so much for sharing your experience.

P.S. - Early in the video, when you have the robot's-eye-view going through the grass, there are times that an ant or other small insect can be seen running around on the top of the robot. ; j

Thank you.

 I' m using a Sabertooth 2X25A, small, light, and so simple to use! Plug the batterie, the two motors, the radio signal and you'r done.

I used relays for the other robot, its rough driving.

How do you drive the motors? do you use relays?

nice work btw, i'm looking forward.

 

NOTE THE 50A SWITCH ON THE BACK AND THE HOOKS ON THE TOP 

 

HIGH GUAGE CABLES PROPERLY CONNECTED

SMALLER SPROCKETS ON THE MOTORS FOR MORE TORQUE

 

Well, thank you guys for your encouragement.

I' m going to try a new gearing because its going a bit to fast, and doesn' t have enough torque to clim steep sand hills without stalling wich heats the cables and ruins the batteries... Add to that the weight its taking so fast!

All this means work to do again.

I hope I can share a little video next weekend.

Yeah, mine has same problem too. It's too fast but doesn't have enough power to go up hill. We need to sacrifice the speed for power. Your chassis still have room to modify but mine is too late. Swap those 2 sprocket should get better result.
