- The gears in the motors add slack that make the limb "wobble".
- The motor axle needs some kind of reinforcement to be used in a joint. In the prototype I just used the axle and nothing more, but I should look into ways of adding support on the back in addition to the axle, and probably add some bearings to add support.
- The geared motors are very long, and it is hard to conceal them in a normal limb body.
|I flattened the other end of the femur and eyballed out places fo the screw holes.|
|I drilled the holes and found some more screws that would sit in plastic.|
|First two screws in place.|
|All 4 screws in place.|
|I decided where to attach the axle wheel to the motor bracket in the hip.|
|I marked where to drill holes.|
|Two holes drilled.|
|Wheel securely attached. I decided to just have 2 screws in this prototype.|
|Motor attached again.|
|Tadaa! Complete limb with knee and hip joint.|
