The goal of this was to securely mount the electrical chocolate bloc provided by the competition organisers to the robot. The challenge was to do
Was it a silly idea at the last minute to add an Pi Cam to capture FPV videos of each of the challenges? Short answer
With time short and the unheard of concept of KISS [Keep It Simple Stupid]. Seriously what’s the point of being an engineer if you cant
As a completely frivolous addition to the robot we wanted it to “talk”. By talk we mean issue Lemming sound effects! Previous jobs involved adding
Its a Lemming, so needed a head to go along with the arm. The game from the early 90’s on the Amiga and the associated

In order to have the robot issue rousing Lemming quotes while we perform the challenges we needed an amp and speaker for the Pi. We
With the wooden part of the arena built (minus the walls), it still doesn’t look like a proper arena. Each of the squares in the
We are at a point where models now exist for all the challenge objects. These are uploaded in their own page here. Three versions of
Following some pretty extensive work on the rotator ring for the robot arm, the power switches and powering the servos from a DC-DC converter connected
While testing the robot arm, the movement is fast enough that it highlighted an issue with the panning servo. After a few movements it was
The servos have up until this point been powered by a separate 4xAA battery pack. This adds weight and another set of batteries to replace.
While testing the robot it would make more sense to be able to power on or off the motors and servos. With space on the
With a completed robot arm this job was to add it to the robot and integrate with the PCA9685 servo board. Some code using the
The code was updated to allow driving via the analogue sticks on the remote control. The left one drives forwards, backwards, left and right while
