We participated in the three consecutive years in the BUTE organized RobonAUT contest. Our team’s name was “Runner-up” and we finished as the runner-up on the first two occasion and we shouldn’t talk about the third one.
2015
We started the development with huge delay because of our study tasks but we always managed to met the deadlines. It was a big advantage to have the previously developed ControlProtocol. In the last two weeks we worked on the car in full time with minimal sleeping. The car looked like this:
- STM32F407 MCU
- Line sensor: 2×32 IR sensor
- 3 db IR distance sensor
- Bluetooth communication
- Torquey servo
- 3S LiPo battery
- Factory motor és motor controller
The final itself went good, the we did obstacle course without any problem but we could not go so fast on the speed-trial.
2016
We started to prepare very early in the next year. We worked a lot on the car from September to the last moments before the final rounds. We had a few new things:
- Raspberry PI, as a WiFi – USB converter for remote firmware upload and debugging. It also worked as an FM transmitter for providing background music.
- New servo: 0.03s/60°
- New line sensor
- Two additional IR distance sensor
- Shiny gold ‘Zsiguli’ chassis
The car did a perfect job on the obstacle course an we were very exited about the speed-trial because the night before the race the car ran an 18.15 sec lap time which is a new record.
As you already know that we finished on second place in this year too, you may suspect that the speed-trial did not went well. We continuously increased the speed of the car in each round, and in the last, fastest round the car did a long break before a corner and took the corner in a larger radius. On of the judges were standing on the course (we still think he stood at a forbidden place) and the car hit his leg. To make things worse he pushed down the car to the ground and our motor burned down. It made a nice “Amper smell” in the building.
