I started this week by working on the design presentation slides, updating the requirements and solution slides after I helped the team make some major design changes to the wheels (by removing them). Later in the week, I received most of the parts necessary to start work on controlling the motors. To that end I got the Raspberry Pi working and started wiring the stepper motors and the Arduino/CNC shield. I also ordered a few more parts from our BOM that would continue to help me get this all set up.
This puts me a bit behind schedule, but I remain confident that I’ll be able to fairly easily catch back up, as there is some leeway in getting the motor control to work.
Next week, I will work on the design document to help fully flesh out our plan. I also hope to finish setting up and evaluating the motors to make sure we can control them well using the Pi and Arduino.
