Over the winter break I continued work on several different aspects. I met with DL, a second mentor and a Robotics major with a focus in Mech. Engineering. During this long discussion we tried to figure out how we can use the current design of the syringe system and allow it to rotate. By the end of this discussion we had decided upon a design that I would continue to look into. The design is similar to how a person's wrist works. Using a shaft that will run through stabilizers (in conjunction with ball bearings to reduce friction) a servo motor will be connected to provide for rotational motion. The servo motor (or geared down regular motor) will provide a high enough torwue to turn the hatches.
I am developing another way to open and close the claw. This technique will unfortunatley discard the syringe system. I will use a servo motor to turn a worm gear which will then turn two circle gears to open and close the claws.
I DONT KNOW IF SERVOs ARE WATERTIGHT THOUGH? that is a problem
