This week, I had a lot of difficulties with getting my mechanism to work.
After troubleshooting with instructors, we determined that my servo had broken at some point and that there were power issues with the amount of voltage that was feeding into the H-bridge, making it difficult for the DC motors that were powering the rear wheels to turn. Another hardware issue that I ran into was keeping the voltage pins on the DC motors from breaking-- I ended up having to buy new ones (the yellow ones broke, the black ones are the replacement).
Admittedly, I spent too long creating an aesthetically pleasing design over making sure the mechanism worked perfectly, which was my downfall with this phase. Over the next week, I plan to immediately replace the broken parts of my mechanism, troubleshoot the wiring, and iterate on the design to allow for a more usable final iteration. Below are some photos of the finished robot and of the robot post-troubleshooting.
