Getting started, what do I need?

as i said above, a number of factors go into the power, batteries and speedos being two. Also; gear reduction, transsmision, wheel diameter, wheel width, tyres, weight balance, speed controller settings etc.

Intereting posts about pushers there.
Alan has relaly knocked the nail on the head in terms of there are soooo many different things that make a pusher more effective than another. Not juts down to power and batteries, the scoop, wheel sizes, gearing, and grippy wheels etc. But also down to gearing and your wheels diameter depends on your batteries also. Kitty used to run on 21.6v on gold motors, but we geared her differently so shes faster as kitty dont have a scoop etc to push, so no need for pushing power, just to run around and ram the blade into people. So many litle things you need to think about depending on which batteries to get.

Yeah i meant pusher . Ok but wouldnt NiMh be good enough for a robot that uses 2 drillmotors as a pusher?

Ni-Mh will be perfectly fine for that

again, depends what motors. Drill motors come in all sizes. I have a little 9.6v drill which would work fine on NiMh, but i also have a huge 30v drill that would be alot run better on NiCads. NiMhs wont take as much abuse as NiCads.

Do you really think hes got a 30v drill???

why not? that was just an example, im sure DeWalts drills will pull alot more power then a 9.99 argos drill.

they do bigger drills you know Ewan. Im sure one of the big nipper guys has a big 32v Drill or something like that. He was well chuffed to get it and use it at Robot Crusade.

I have seen a 48v drill with a 3amp sanyo ni-cd pack on it. I was so tempted to stick the battery pack in my back pocket but i didnt.

Dewalt 24V drills are rated 24V, happy on 36V if you do the dustin mod (or in their native state as long as you dont load them too much) and are 2HP peak. In other words, a slightly different league to argos £4.99

my point exactly!

Very true, but Danny isnt going for a DeWalt power robot, as his budget is way too low.
