Frame is made from 1 inch square tube mostly, with a 3/16 plate steel skid plate. Its very sturdy frame, has been tested and no flex even with wheels in the air.
4 large wheel chair motors, all matching with same rpm. Custom built wheel adapter spacers fabricated out of 1 inch thick aluminum.About 12 hours plus in fabrication time for wheel adapters alone! Tires are 13 inch tall garden tractor tires, on 8 inch aluminum rims. Rims have hand painted camo on them. Dual 12v Li-on 100ah car batteries, group 24 hooked up in series to run 24v. Robot has camouflage vinyl wrap, and duck tape covering all the external surfaces. Control system is Dragon Link 900mhz system piggy back on a Taranis plus remote. Kill switch and circuit breaker are heavy duty car parts. Control box contains, dragon link receiver, servo power supply, adjustable voltage regulator set to 12v, and led light driver not hooked up to anything right now. Motor driver is smart driver duo with upgraded whisper quiet fans, with camo on it of course. Has a 2400mhz wifi antenna, and router on the back.
Comes with chargers for battery pack, and remote. Ok that's a lot to take in, but any questions about my bot just send me a message. Was built to use as a mobile camera platform for long range video viewing. The power to weight ratio, and short wheel base makes it too bouncy to use as intended.This thing is both fast, and really scary if it gets out of control. You will only let it run you over once, after that you make sure to get out of the way lol!
The motors are currently programmed to only 40% power, you can turn it back up to 100 if you are really brave. Calculated top speed is around 13mph at full power, but I did not test actual ground speed. At 40% it's faster than a jog and controllable. Can be played with as is, or add something to it give it a new job function.
If you are local, I would be more than happy to demonstrate it. One minor issue is the dragon link antenna mount came off the circuit board, can re solder it back on or replace it.
Will work at short range, needs repaired for proper long range transmission. The dragon link can go for miles, look them up! As for cost to build I stopped counting, I have several thousand in this and just looking to make some of it back. Ok this weighs over 200 pounds, I can't ups this to you. If you are paying I'll send it.If you can get a better price you can book it yourself, prices are sky high right now due to covid and I have no control over it.
