So I was writing my bit about solar power and needed to build a solar tracking mount to generate real world figures when I found the cheapest way to do it was buy an off the shelf robot kit....and then another...!!!

The intention is still to use it for solar tracking but I got a whole range of bits and before they get separated and modified I thought I should at least assemble them as initially intended and experiment.

The first kit I bought was a small robot arm made from laser cut wood and four servos. This was mostly ideal as it would allow me to mount a small panel and position it where I wanted.

The second kit I bought was a small two wheeled car, which included an Arduino Uno, a servo board, stepper motor driver, motors wheels other hardware, and a tilting and rotating camera mount worth half what I paid for the whole kit. Mmmm, I'll have another those!!

So this is now a brief write-up on two robots I didn't intend to start.

The two kits are:
