I was trying to calculate the torque for my robotic arm from this website calculator
Here is the spec
motor Hitec ,Torque 10 kg/cm
L1 (Length from shoulder to elbow) 7 inches weight W1 steel frame about 5 g
L2 (Length from elbow to wrist) 5 inches weight W2 steel frame about 4 g
L3 (Length from elbow to gripper) 3 inches weight W3 steel frame about 2 g
W4 object to lift 1kg
M1 (Shoulder 1 motor ) 25g
M2 (Elbow 2 motors) 50g
M3 (gripper 2 motors) 50g
I want to lift 1kg object
I left the Joint Rotational Acceleration blank 0
It is showing about 40kg/cm torque ,Is it correct?
If it is true ,is there any way around it?.
I could not find any servo motor with that torque.Even if I do find ,it will be pretty expensive
