This week I modeled and printed a prototype arm. The design is 4 axis suction arm with 3 motor axis and 1 servo axis. I routed wires paths through the 3d printed parts and worked to achieve part tolerances. Currently we don’t have all of the hardware to make the arm function: we need angle sensors, servos, wire, suction parts etc.
I would say that we are on schedule to have a working robot arm in the next few weeks.
Next class I want to wire angle sensors to the Arduino and potentially motors to control the arm. I also want to test out the suction gripper. I will continue revising the hardware.
