Hello LMRians,
Making a 3kg class sumo robot and am making use of A) 2x 18kg cm motors or maybe b) 2x30kg cm motors ( trying to fend off some tough competitors ;-) But, my question is, will my bot handle that much torque?
Yes, wheel traction will defnitely play a role, So i am using high traction polyurethane wheels of 2.5cm radius. And it's a 2WD version.
so accd to my crappy calculations,
the total torque i would require is (2.5 x 3)/2 kgcm per wheel i.e. 3.75 kg cm.
And pushing my 3 kg opponent, a more or less similar figure of 3.75 kg cm.
Total torque i would require is 3.75 + 3.75 = 7.5 kg cm torque.
Now if i use motors A, total torque that can be produced would be 2x18 kgcm = 36 kgcm or using motor B 60 kgcm!!
I want to know what is the range of torque that this 3kg fella could handle? Is it possible to go in the 60 range or stay in the 30 range or lower?
Will there be some flips and turns due to too high torque or will this be a killer sumo? I know, you all would need to conduct a whole bunch of tests, but what do you think of it from a theoretical point of view? Thanks guys :D
