Hello, new member here! I live in Germany but come from Texas!
And yes you read it right. I want to build an electric mechanical cow. It should be electric of course. It will have tracks instead of wheels. The tracks stop the "cow" from bouncing so much in the sand in the riding arena.
Of course the tracks add much more complexity to the build as far as the needed torque and drain on the batteries but they are necessary. This "cow" should be about the size of a garden tractor and be remote controlled!
All the fabrication and machining is no problem for me. The CAD drawings are also no problem. The "problem" is all the electrickery involved. Not so much the remote control but the correct motors, batteries and controller, etc..
So that is why I am here.
It needs to have very good low end torque and the tracks need to be powered independently of each other so as to facilitate the tracks running in the opposite directions of each other. Think bulldozer, tank, excavator or Z-turn lawn mower.
If it would be advantageous to incorporate hydraulics in the build that would be no problem for me either.
Run time should be capable of minimum of 30 minutes.
What would all you experts recommend for the electric side of things?
Thanks in advance for any input. It should be interesting to say the least!
