Hi Mates!!!
I am currently stuck in a position where I not sure how to robot system will behave.
I plan to use 2 Electric Motor on Hip and Knee segment of leg. I was wonder if there is any suggestion on how to allow the actuator at hip to be slightly flexible yet provide rigidity for support paralyzed person after performing forward step.
For instance after moving left leg forward. I would like the motor to be slightly 'relax' so that individual can transfer his weight forward and move his body forward. For my understanding, if the motor if too stiff it will be quite hard for the person to make the forward move.
Because I heard that DC motor with integrated gear box is quite stiff and hard to move them.
Can someone help me on this!!!
