Today I worked on the end effector attachments for the arm. This included the simple drill end effector as well as the claw end effector. I already had prototype CADs of these, and I previously had redesigned the arm to make it lighter and improve the range of motion with better motor placement. So today, I adapted the end effectors to work with the new arm design.

Things that still need to be worked on:

• Make the claw lighter and shorter
• Update the CAD with all the fasteners and other hardware
• Make the parts list for the arm
