I wanted to confirm some motor calculations with you guys. The robot I am building uses treads and will operate on various surfaces that have a high coefficient of friction (mud, grass, carpet, concrete, dirt), which is why I inputted a low efficiency. When I put these same specs in on the calculator at TheRobotShop, I got different results. According to the calculator on TheRobotShop, I need insanely high wattage motors (talking thousands).
The robot itself is only 200 lbs, but it will be pulling 150 lb loads (250 lb max), which is why the weight is so high. Also I will only need to pull these loads at about a 10 degree incline, but the robot itself will have to climb 30 degree inclines when its not pulling that load
That just didnt seem right which is why I'm double checking if 24v 900 watt motors will suffice for what I need.
