I need a motor / circuit that is capable of doing the following functions:
- Switch between four Torques levels - (2.5Nm, 5Nm, 7.5Nm and 10Nm)
- Does NOT need to rotate continuously. Preferably staying within 0 - 180degrees of motion
This circuit connects the "hand" and the "forearm" of the robot through a shaft that is positioned at the "wrist", with the intention to simulate flexion and extension motions of the wrist.
However, the level of torque applied must be constant with the 4 different torque levels stated in the requirements.
Can anyone provide any suitable ideas on how to construct the circuit, and/or suitable motors/servos that I can utilise?
