Whew! Another long time since an update on the RC Car project!
There have been some major developments on the project since last time and I’ll go through them here.
After the last update, I did design a PCB to condense the project into a neater form factor, however there were several issues with the design and ultimately the board was nonfunctional. After spending a few days attempting to get the board working correctly I made the decision to put that on hold and get the car working again (it was dissembled for parts). This was supposed to be a simple task considering I had done it once but after several days of work I was left unable to make the radio modules communicate with each other. It was at this point I decided to move the system to a new platform.
RC Car Project - Update 2
Zerobot Project - Update 3
This week the new parts came in. I tested the operation using brand new Zeros and cameras. Found a defective motor controller on Zero 2.0. After replacing it, the wheel no longer rotated prior to booting up. I have successfully created an SD image file to burn onto any new SD card that operates a new Zero correctly. The only change in the file is correcting the IP address to the one of the new Zero.
Zero 1.0 and 2.0 are both fully functional. For the tires on 2.0, I was having issues printing the NinjaFlex so they were printed with PLA. This created traction issues and I attempted in overcoming those by wrapping the wheel in electrical tape.

Zerobot Project - Update 2
This week I have completed Zerobot version 2.0 and have gotten 1.0 working to spec. As always, Issues have arisen. Version 1.0 was working perfectly on Friday, but on Monday, the left wheel would not rotate counterclockwise. I installed a new motor with no change in result. Version 2.0 operated with the same SD card as 1.0. The motors would operate on port :3000 but I had no video stream. The video stream would operate on port :9000 but I had no controls. Another issue on version 2.0 was the left wheel would rotate when power was turned on until the Zero booted up. Once the Zero booted up, the wheel would stop and operate correctly.
