Thread: Just Getting Started- have loads of stupid questions.

I've been a mechanic since leaving college over 30 years ago and currently work with hydraulics and LPG systems all day in the world of forklifts. A bit of CO2 holds no fear for me. I'm well aware of the precautions you need to take around this kind of stuff, but didn't know if anyone had done a walkthrough of how to build such a system. Yes, the pressures in a CO2 bottle are higher, but at least it's not flammable!

Slight hiccup when it comes to motors. The pallet truck motors are massive and not suitable (never really clocked their size before).But I've noticed that the steering motor is about the right size and has about 4:1 down gearing. they are however, brushed and not brushless. I've read that brushed motors are, due to their inefficiency, much more tolerant to stalled conditions, so they would possibly make better motors for a robot. they are only 185W @ 24V, but being industrial motors will be massively over engineered so they don't fail over thousands of hours of use. Would I be correct in thinking that the torque increases at a linear rate with the reduction ratio?
