First link is only requir to move between 0 and 80 degrees so the servo won't need to fight against it (not too much :) ).

I need about 18kg*cm of torque (approx 1.8 Nm) so I'll use two servos linked in parallel (each motor can provide about 10 kg*cm), the problem is only in the first joint.

I calculated the forces for the worst case scenario, in reality it might not be as much force aplyed, but that is why I want to add that spring.

I did the math and the torque required for the first articulation is almost equal to the maximum torque that can be provided by the servo motors (and it might stop working). The highest torque is required when the arm is parallel to the ground (but I might be wrong, I'm not really sure about...

Hello! I have to build a robotic arm and I want to use servo motors but the problem is that the strong servos with high torque are quite expensive. So, my question is, can I use springs to reduce the torque required?
