Today, I worked on continuing to print the leg pieces for my robot. While there were some minor setbacks in the process, as one of my attempts to print all pieces of a single leg at the same time failed, I managed to print the pieces of a second leg. To solve the issue where the printing material failed to stick to the surface of the 3D printer, I let the machine cool off before restarting it for printing. To avoid further complications caused by the premature cooling of the pieces in the printing process, I chose to print the legs by sets of 2-3 instead of all of them together in a single file. 

I also discussed with Asli about how the stepper motors were going to be controlled. Due to the fact that the raspberry Pi was only shown from my research to be able to handle at most 6 stepper motors, I decided to change the design of the rear legs. While the front legs would retain my original design, the rear legs would have a much simpler layout (with only 1 stepper motor per leg).

After meeting with Tim, I listed a number of things I need to do before using the Raspberry Pi to control my legs. First, I plan on learning how to code a Raspberry Pi through a RC car mini project. Then I would learn how to connect and code the stepper motor controllers. Once this is done, I would need to test my legs on a testing rig, where I would figure out how the legs would move and how they would do so in accordance to other legs. Finally, I would assemble the whole robot.

Next class, I plan on starting on the RC car mini project. I would also be working on the design of new rear legs.
