Motor selection for Humanoid
I have recently made a 6 degrees of freedom half-humanoid (no torso) using springRC analog servo. But, I realised that it cannot be made to walk unless the hinges are rigid. Joints are made of plastic.
After much thinking, I decided to make a new humanoid with parallel plates connected to one shaft. This way, the legs will not bend much. But, in most of the humanoids, that I have seen in instructables, 2 servos were used to control a joint. This will make it costly and program intensive.
Has anyone seen a servo motor which has a double ended shaft? I have browsed through Futaba and Hitec motors, but in vain.
Please help me out on this.
