I'm new to the forum and this is me saying hello.
Inspired by the last series of Robot Wars and my purchase of a 3D printer I've decided to build an antweight-ish 'bot. I help run an electronics club so wanted to do something modular which other people could quickly pick up and modify.
So I designed a 10cm square chassis with 2 wheel drive (from a pair of FS90R continuous rotation servos) and scope to add one of a variety of weapons (or another couple of drive wheels to make a 4WD shunter) via a fixing at the front. The electronics are managed by an Arduino currently on a breadboard balanced on the weapon platform. This will get shrunk down to a PCB in due course.
The current version has drive control via IR but I've got some 433Mhz radio modules to replace that with. I hope to get a few bots built and have some PlayStation 2 controllers plugged into another Ardunio which will relay instructions to all the 'bots. Will hopefully be cheap (ish) with more control options than standard RC boxes.
So yeah, video, with forward/backward at around 50% power: https://www.youtube.com/watch?v=uQsgtNhBE5g
