Black is the New NavBot
Created a new bot better suited for dead reckoning navigation. And the results?
Quick and Dirty Dead Reckoning
Put together a quick and dirty dead reckoning experiment now that the encoders and PID controller are working. Very happy with the results, even if they are superficial.
PID Tuning For Zumo
With the encoders working it’s time to tune the PID controller for driving in straight lines.
Building Zumo – Encoder Redux and Bluetooth
Discovered there was an alternate and simpler solution than using Trinket.
Also received a bluetooth module and put it to use.
Building Zumo – Part III
Completed the Zumo hardware side and got the encoders working but then hit a road block trying to get the motors to turn…
Say Hello To My Little Friend – Zumo Part I
Decided to build the Pololu Zumo chassis with their optical encoders.
Still need to figure out a circuit to convert the encoders’ analog signal to digital.
Data vs Reality
I’ve implemented a PID-based closed-loop system to ensure my bot travels in a straight line.
The data says it is going straight, however, in reality it seems to be deviating quite a bit.
Mighty confused.
Wheel Encoders For WallBot
Adding wheel encoders to WallBot ended up being more work than I thought. I ended up writing all the code from scratch but it meant I learnt a lot about encoders and timer interrupts on the microcontroller.
WallBot – Version 2.5
WallBot got a new motor controller and quadrature encoders.
Integrating the new motor controller raises some software issues….
