PACERBOT Parts 21 -22: Stadium Speed Controllers at the

Following the last post, I took the robot out to the stadium to check how it performs.





PACERBOT Part 17 – 20: The Last Encoder

8 06 2016

How I transformed an IR sensor into an encoder, that enables the calculation of speed and distance.

PACERBOT Part 16 : Algorithm talk

29 05 2016

PID is finally starting to work. Apparently the last issues were not entirely caused by bad tweaking but by “bad” coding as well. Read the rest of this entry »





PACERBOT Part 13-15: Stadium Runs

29 05 2016

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.

PACERBOT Parts 8 – 11: Custom Optical Encoder

25 05 2016

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.

PACERBOT – Part 6 + 7

21 05 2016

A peak into the PID tuning process. A good demonstration of the various effects changes in the parameters have on the behavior of the robot.

PACERBOT Part 4 + 5

The design,printing and assembly process of the resting place for the battery. A rectangular box that seats on top of the transmission serves as a holder for the Arduino board in addition to a battery holder. A straightforward, though important part of the robot.
