So we attended PiWars 2019 yesterday, and failed miserably with our robot - J2. It broke down on the second event of the day, struggled with the third event and went up in smokes on the fourth. We came 15th (last) in our category. It was a sobering lesson in robot building and failures. I have blogged a lot of what I did with PiWars bots in the past, but not always focused on the fails, so I think the time has come for me to detail the fails, if nothing for myself to refer to.
