Semester 1 Spring 2018


GM Robot Arm Automation:

    This semester I worked with Zach and Dan on the GM Robotic Arm project. The arm's purpose is to remove a 3D from the bed so a new print can begin. This would make the process possible without being in the lab at all. Using Octoprint, we can start the print from anywhere with internet, and with the arm, we can clear the bed. When I joined this semester, the arm was mostly assembled, so I do not know much about the specific mechanics of it, but I did most of the programming for the arm. I wrote some step by step code in DDE in JavaScript. They are small line commands that tell the arm to move to specific places. There is a large cage that we have assembled. It has a 3D printer and robotic arm inside. It also has some cool LED strip lights that light it up. As of right now, there are several limitations with the arm. We have to push a button on the laptop to start the robotic arm once the print is finished. Also, the code for the arm only works for one specific print. I learned a lot about how the arm works and hope to continue working on it next semester so it can be used to its full potential. Next semester the plan is to try and make the arm and the 3D printer talk to each other. When the print is finished, it will somehow signal the arm to begin the motions to remove the print from the bed. This way we don't have to push the button on the laptop. We also want to eliminate the need for the laptop. We have a raspberry pi that can start the print outside of the cage, and we think it will be possible to use DDE on it. The next step to improving the project will be to add some sort of feedback on the gripper. There was some issues with the first servo that we used for the gripper. The conclusion was that we pushed the limits too hard and stripped the gears inside. If we have feedback from how hard the gripper is squeezing, we can eliminate that issue. I am glad that I got to gain experience working on this project this semester. 

Semester 2 Fall 2018


GM Robot Arm Automation:

    This semester I was in charge of the team working on this project. The first few weeks of the semester I introduced the arm to the new members of my team. After a few weeks we met up and
