The final video featuring PACERBOT.
For additional information about this project, the way its software works, and the thought behind its design, take a look at the detailed video log series. All the episodes can be found in earlier posts.

Following the last post, I took the robot out to the stadium to check how it performs.
How I transformed an IR sensor into an encoder, that enables the calculation of speed and distance.

PID is finally starting to work. Apparently the last issues were not entirely caused by bad tweaking but by “bad” coding as well. Continue reading “PACERBOT Part 16 : Algorithm talk”
Some footage of the robot running in the stadium. The process of tweaking the PID values is tricky. Even after a long time working on these values, I have given up (for the day!) and stayed with slow speeds, which are easier to work with.

Measuring speed can be done in many ways. I chose to build an optical encoder, to sense the frequency of the drive shaft’s revolutions, and calculate the speed by recording the time between pings.
