first robot

no but you should match your batteries to your motors to keep the speed realistic as they will be full on or full off in forward and reverse so you need to make the speed enough to be drivable .......

I thought it was microswitches, sevos and relays that were used to give direction control?

im kinda confused about these switches. would it be best for me to buy speed controllers if i can afford them?

Its always best to buy a speedo if you can afford one ..... I used servo's and micro switches because the robot they were in was designed to be smashed up for the crowd so nothing exspencive went into it but they work well ......

ok i think il go with speed controllers, do you think two of these will do fine?:

they are Â£32 each.

i would highly recamend getting a speed controller, cos although dpdt switches/servos will work ( im using them in my 4wd axe bot) speed controllers give better control and can be used for other robots later. buy somthing good now and it will pay off in the future

Those will do you fine. Been using them for years. Tried a couple other controllers and have found the electronize to be far superior due to their simplicity, ease of use, cost and current handling. Went back to them after a sabre tooth and sidewinder.

thanks, im going to start ordering the parts tomorrow. probably would be best if i check everything is running the way i want before i start designing the base.
