This week I was gone for the whole week at the society for neuroscience conference but my group made an awesome delta picker machine which can be found here. My group's machine My contribution to this week was creating cad designs for various parts of the machine. We first had a meeting with Jake to discuss different designs and look at the dimensions of the stepper motor etc. We sketched some design thoughts that you can see below and Priyanka worked a lot on calculating the minimum dimensions of all the parts given our weight and movement constraints.

I adapted Jakes rack and pinon design to fit our needs and created a few different end effector designs which had a hole in the center where a variety of diffent attachements could go.
