I didnt notice the pictures before

That self drive linkage is off a very early modle Rover mower. The shaft the wheels are on is susposed to friction drive on to the wheels via cast iron toothed drive dogs .

If you use that set up with both wheels fixed to the axel and one motor driveing you will never get your bot to turn it will just go in a straight line unles you put some sort of diferantial in the wheels or drive shaft .

Hmmm ......Not sure about that ............ Onslaught had / has NO differential.

Then Onslaught probaly had heaps of grunt to get wheel spin i doubt a ww motor will do that

yeah but u can probly get around that by making the bot long or having a poor turnig circle

Hi again

yep that is a bike de-railer cog wilko, I have broken them before, so I got a fair few of them together just in case .

Yeah that is an old rover self propeled unit Totaly_Recycled,I have had it sitting in the shed for quite some time so I'm going to put it to good use now.

Well my plan was to have the 2 back wheels solid on the axle and have the 2 front wheels to steer with so thats the reason I'm using that old frame.

Simon

Well I went looking through all the stuff in my back shead and found an old CAT AC condensor fan motor. I is almost 3kg, 24v and is just the right size for the cogs so I think I might use this unit instead of going to the scooter motor for now.Dose anyone else out there run 24v motors in there robots?

Many robots run at 24v, especialy ones which need the voltage for their weapons. I think Jeff F has gone the highest here at around 36v when he ran his brushless motor in cyclonite... There's a huge range.

YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH

The scooter motors are all 24volt.

Most car fan and heater motors are 12volt or closer to 14volt as that is aprox what they run on when car engine running and alt charging.

These often end up overvolted and can end up running on 24volts.

With Nicads etc packs are often made up of as many cells as the builder decides on, this may be a compromise to run both weapon and drive of one pack.


Sounds like you have a good motor there, take 36volts no worries.

Thanks for the replys
Yes I shud have known the scooter motors are 24v *bangs head on keyboard* Now I feel like little billy.

Yeah I think it should be a nice powerful motor I'll try and get A picture of it up some time
