    Re: first robot

    Its fairly simple once you see the bits laid out. RC cars don't always work in quite the same way. A good thing to do would be to try and come to an event, any roboteer on this forum would let you have a look inside their machine.
    Put basically though, your basic 2 motor speed controller has a place to attach the 2 motors, either by screw block or solder, and a place to attach the battery, and then leads that plug into your reciever. And that's basically all it is, minus essentials such as removable links and power lights, but they're easy enough.

        Re: first robot

        im 14 and i manage :P. IF there are any local events ion the horizon try and get your parents interested, its a fun day out evne if your parents dont like the robot bit much . Or try and find some roboteers near you and ask if you can visit them and have a look at there bots, you really need to see a combat robot in the flesh before you start building or you start designing it with goals not suited to a good combat robot, my first bit was un upturned inbox with mdf duct taped to it !!!

                definitely enter an event, you meet some great people and everybody is very helpful and dosent mind you constantly;y asking what happens next for your first few events, i think i drove Dave insane with that very question .

                Even if you instantly get immobilized or flipped out, its a great feeling to get something mooving in the arena.

                    Re: first robot

                    ok thanks il get to one once my robot is done, even if its just to watch.
                    im going to build a lightweight, partly because im building it with my brother and he wants something with a bit of power.
                    or the motors i picked up 2 of these scooter motors:
                    http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWNX:IT
                    what battery's and speed controllers should i get for these motors?

                      Re: first robot

                      I dont think that was a good idea . Gearing scooter motors and attaching it all to wheels relaibly is a big big undertaking unless you have very extensive experience with gearing and low voltage dc motors (its unlikely ) It will be a lot more difficult than you think to get a rolling chassis. Id recomend at least one bot with blue wheels and drills, once you feel that you know people that can help you with the scooter motors and you have looked inside pinser (that uses scooter motors i think identical to the ebay ones), then sell or store the drill motors and begin replacing it with scooter motors. As for the batteries, 2 7.2 V nicads or a 12 V sla battery.

                          Best to build a feather, not a lightweight, because there are very few lightweights and so it will be very hard to get fights.

                            ok but i have already paid for the motors for my robot so i might make a lightweight and see if i can lower the weight to make it feather if needed.
                            does anyone know of any speed controllers that can take the 24v? also does anyone know of a 24v 100 watt battery (if that is what i should use?).

                              hi there wow I cant believe 2.4g setup is £40 come down loads in price, wonder what the output mw is ? just noticed you were going for a lightweight, well at most events they run
                              heavys or featherweights so you wont be able to compete with a lightweight.
                              most roboteers for f/w use sub c stickpacks about 3-4 amps for their batterys,
                              nice and simple !

                                ok thanks, do you think i could use just one for each motor or should i connect more for each motor?
                                EDIT:
                                i found these: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... ink:top:en

                                do you think two for each motor will be ok for FW using those scooter motors?
