To make the robot go as fast as possible, we decided to do some experiments with gearing. A few examples of the prototypes can be seen below:
After some guidance from Lasse, we realised that chains was not the right way to transfer power. We rebuild the robot to use only gears. Pictures and movie below.
The gear mounted on the motor have 40 teeth, while the gear connected to the wheel have 20 teeth. This should double the speed of the wheel. We also use the biggest wheel to get higher speed.
PID
We have tried to implement the PID-controller from [PID]. We got it to work somewhat, but the parameters need alot of tweaking to make it follow the line to perfection.
We decided that it would be more useful to make a scripted car, to get the full potential of the gearing.
Scripted car of doom!
Video will follow. Work in progress. But it is awesome.
