Zerobot Project - Update 3

Aug 14, 2017

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.


Working on the design for 3.0. It is sized between the two and incorporates all electronic components on the lower shell for ease of access. The battery will be held in the upper shell with a wire pass-through for the power cable. I am finalizing the design and ordering a specific set of hardware for the 3.0 model. The next writeup will contain step by step instructions, Solidworks models for customization, and STL files for printing.
