not just any pusher, a superpowerful one.
how about 6xRS-775-18 drive on 24volt to give over 5horsepower.
i love the robots bonx and satanix and.my aim is to smash robots into the arena and crush them.
i have the money and determination and the ability to do a messed up CAD.
only issue is speed controllers,
6 electronize 30amps will take me back £250.
what's the cheapest speedos i could get hacked brushless to brushed?
i will use mod 1.5 technobots 17mm thick steel gears with a 4wd system.
could i have a larger wheel at the back and smaller wheels at the front all connected with bike chains?
thanks.
I know its all good having 5 horsepower, but lets just think for a second, 1 = a featherweight will never be able to put that sort of power down and will just spin the wheels unless you use magnets ( only anygood at robo challenge event as there floor is metal), 2 = Weight 6 gearbox motors will weigh alot aswell as the batteries and speed controller needed to run them 3 = Very expensive,

Just think about cobalt runs 2 x rs550 (£7 motors) on a pair of banebot gearboxs and that has more than enough power to smash other robots around, also think about if you get under the other robot you can push it using bosch 35watts ( not needing all that power )

Look at what other people have done and decide what you want to do, a good drive train can be cheap if you pick the right parts
