Re: motors

I think the scooter motor will be more powerful but that's just a hunch. Both motors would need gearboxes though, with the scooter motor it would be fairly easy to have a reduction using chain and sprockets but for the Mikita motor you would probably need the matching gearbox. If I was you I would go for the Gimson motors or Argos value £12.50 cordless Drill motors for your first bot, they are very simple to use and ou don't need to worry about gearboxes.

For my first bot I tried to use windscreen wiper motors despite everyone advising otherwise and still haven't managed to finish it due to complications and difficulties only caused by the motors. But I have managed to make 3 robots using drill motors and robochallenge wheels, it's just so simple!

Re: motors

The Makita motor is the more powerfull, smaller, lighter but with a much higher RPM.

The scooter motor is large and heavy, but with the lower RPM easier to work .

Concerning batteries. you can't do much wrong with the vapextech one. But you'll need 2 of'm for the scooter motor, the Makita can work on the 8.4V of the first Vapextech pack.

Re: motors

ive used argos ones in my 4x4 robot and they are defiantly cheap and cheerful but for my second robot i found these http://www.ebay.co.uk/itm/BRAND-NEW-GEN ... 35b8213ae2

they work out about the same but you don't get any battery but most people don't use the drill packs and they are better build quality and a bit faster

the seller also has some more expensive and more powerful bare units

Re: motors

thats really helpful but will they power my robot

Re: motors

Do you mean are they powerful enough? If so then a lot of robots use those drill motors and they are quite fast and powerful, you won't be the most powerful pusher but for your first robot there great! If you want more power then you can go for gimsons which will be more powerful.

Re: motors

i think i will get gimsons if they r in my price range but my robot is a thwackbot and needs alot of power

Re: motors

Plain grimsons are £24.50 but you can choose conectors and wires for them as well for an extra £1.70

Re: motors

the scootoer motors are more powerful and will probably give me more impact when i attack enemies but i dont know what would be suitable for this esc:

the only reason i suggested the scooter motor is because they are cheap and i thought they were good but if push comes to shove i will buy the gimson motors.

A quick question, which of your robots were most successful? what kind of robot are they? did you have any tactics?

Re: motors

scooter motors will end up costing more than the gimsons once you buy gears.
also, i don't like the sabertooth escs, they are a little fragile, try some electronizes much more rugged.

oh, i have a lifty pushy boring robot, runs 4wd off of 4 GR01 motors and it can lift around 50 kg
