@Haywire The wheels are from a quad bike trailer (ebay £55 for all 4, new about £60 each) 18 diameter. Its running boschs, origannly on 36v (in the videos) but ive since had them rewound and it seems to have lots more power, so i've dropped it to 24v as it was it lively on 36v, kept wheelying and rolling over forwards!

Matt, i really suggest you aim for the 50kg mark, any more than that you start needing heavyweight stuff. Pair of wheelchair motors, old 4qds (or the wheelchair controller) and a pair of sla's means it can be done cheaply, if you were to build Omega from scratch then your looking £2000

It won't be an omega replica, just something which is inspired by omega

I got a few different ideas in my head with a few different options to look at

Re: off road non-combat project ideas

There have been a few people that have built robots for school projects and nearly every single one came VERY close to failing. Why? Because of time and cash restraints. Plan to build something as simple and as easily as possible. Two wheelchair motors or windscreen wiper motors, basic speed controllers on a basic chassis with two large wheels will do the job. The teacher won't care if you are running 24v motors on 36v with 4WD, they will likely only care that it works.

That was what I found - originally I was going to build a featherweight with a pneumatic flipper for an Extended Project, but my ineptness and focusing on my antweights led to that going out of the window and I built an overhead thwackbot antweight weighing less than 100g instead.
All the teachers were so impressed with 'TINY ROBOT THAT WORKS~!' and the accompanying dossier of misinformation presented entirely in the third person that they didn't notice how rubbish it was, and I ended up getting quite good marks for it and my college offered me the use of the school hall to host an Antweight World Series, so...yep, go as simple as possible and perfect the design later on (or, in the case of my project, disassemble it and send the parts to Canada!)

That's the aim, keep it simple and cheap. Wheel chair motors I can get, pair of esc's ain't a problem and already have two sets if bike wheels. Then it's just sla's

Thankyou, I have plans for a small invertible one for playing around with at the local common.
