That drill motor is exactly the same as one used in another students project, and its tiny. That 810:1 ratio must really be needed to shift a FW.
Ill try those WW motors for now, and once its finished and presented for my project, I can upgrade it with my own time and money (I have to finish it very shortly :S)
Thanks a LOT for your input guys :)
Nah, the same model is used in the Zeobot robot, I belive the ones that the zeobot uses are 11:1 or around that.
The 11:1 model from technobots looks really good as far as the specs go.
Ewan is quite right, the Zeobot uses a 11:1 ratio which drives a 64mm diameter wheel to approx 11mph.
David, there are a number of similar looking MFA motors with ouputs from a few watts to the largest of over 20W - the 919 range so it may not be the same one.
What the Zeobot has done though is to use multiple motors where greater power is required and attached the wheel in a very reliable way. As the Zeobot is commercially available, it could not be just bodged on as Im sure customers would not be pleased.
The 4-wheel drive version performs really well, the 6 and 8 wheel drive versions are something else.

Im gonna use the wiper motors for now, but I need to know, do I need to do much modifying for them to be robot ready so to speak
A group of my engineering students are buying a kit C 4WD Zeobot after xmas. I cant wait to see what its like. There going to use a linak actuator to make a razer type crusher
I cant wait to see how any of these zebot kits perform actually, they look great.
I want peoples opinion , do you think i could run 6 18v drills on a IBC at 24v.Im really trying to the extreme
Chances are Alistair you will damage your IBC, KO and Aussie robot uses 4 x 12v XU1 drills on 24v and gets its IBC warm, I would hate to see what 6 would do.
The robot Singularity has 6 x 12v drills @ 24v, but it runs an RD80 Robot Solutions speed controller with the current limiting cranked up.
I agree, my IBC gets hot with just 4 12v 800 hobby motors on 18v, 6 18v drills on 18v would be fine but overvolting 6 motors on the poor IBC would be risky.
If you mount a whooping big 90mm Vantex Tornado fan onto the top of your IBC and have the cooling holes like in our IBCs, you should be able to get away with 6 x 18v drills at 18v. Mainly on the fact that I dont see how you could stall more then 2-3 motors at a time. Your wheels will spin before then or the gearboxes will give way.
Here is a picture of Singularity(http://www.abbl.org/~teamvertex/photos/singularity.jpghttp://www.abbl.org/~teamvertex/photos/singularity.jpg) as it was at the Marayong Annihilator 2004, it was running 6 x 12v drills @ 24v with relay controllers, he seemed to only keep blowing reverse in the relays until he eventually blew the whole controller up.
