As you can appreciate, a lot of experimentation went into the build so the team could see what worked and what didn’t.

Exhibit 1: 3D Printed palm top Rover with printed clip-on pieces

Exhibit 2: Pi zero W, Camera, 2 micro motors, a TB6612 for the motor driver, a lipo battery for the pi and a Zumo chassis with 4 AA batteries and quite a lot of blue tack to hold everything together.

Exhibit 3: Tank Robot Kit With a single servo that looks left and right when it is close to an obstacle to find another route.
It happily hits low obstacles and drives over them or falls facing up depending on the angle. It also has Bluetooth included.

The tank tracks have so far been one of the most favourable approaches from the team so quite a few tank models were built to test the tracks

Exhibit 4: RC wheels  and stepper motors anyone

Exhibit 5: 3D printed micro Rover – cannibalised power bank running a Pi 3 A+

 

 

 

Exhibit 6: Lego Steering Experiment – How can we replicate this type of steering

 

 

Exhibit 7: The wheel base presented its own challenge for manoeuvrability so the experiments on the base began quite early on. This 3D printed model was tested.

 

Exhibit 8: Another Tank Kit, you can never have too many tanks

Exhibit 9: I spoke too soon

Sammy – The Lego RC tank

 

That’s a whole lot of robots! The Pi Wars Team have certainly been busy this year
