@theone1728 @Joshua_L ... I like your thinking ... but a 2 inch wheel radius means the carry capacity needs to be divided by 2 ...
He did that, and then multiplied by 2 for 2 motors.
@theone1728 also that is peak torque and that only occurs at and below 50% motor speed, so based on the peak torque clearly being flat below 50% run speed implying a built in clutch to limit peak torque.
Yes, you don't want to actually handle this load.
@theone1728 And not the scaling .... 100 rpm ... not 200... it seems odd cause the motors seem like they should run fine 2 motor drive at those speeds but who knows ... sorry man i wish i knew all the needed math but its been too long.
I do know at NBN worlds our bot was 23-24 lbs on 6 motor 393 drive running turbo (240 rpm) on 3.25 wheels too my knowledge... but i have no idea what else to do other than run someone with v5 run some tests with minimal friction and please post the results here ... but my intuition says 2 motor 200 rpm on a 4 inch wheel should be possible around 10-11 lbs
You're not driving the robot up a vertical wall. A generally robot won't require its weight's worth of force to move it about.
