Re: first robot

cant hehe. what esc did you end up with? also are you using 2 or 4 drill motors ?

Re: first robot

i got 2 electronize FR12VR, and im using 2 drill motors thought 4 may cost too much for mounting kits and stuff.

Re: first robot

anyone have any suggestions for the front wheels, i want to keep the ground clearance low and was thinking about using ball transfer units like the item at the topvhere:

anyone think it will work?

Re: first robot

You could make a good front skid out of UHMW (aka poor man's teflon).

Even a round headed bolt might work.

Re: first robot

thanks, il have a think about what will be best once i get my wheels attached they should be on tomorrow if the pop rivet gun i bought of ebay arrives.
EDIT: what you mean by front skid?

Re: first robot

a part of the robot that skids along the ground without a wheel

Re: first robot

ah, ok thanks il wait untill i get my drive wheels fitted and see where i can go from their.

Re: first robot

I meant a skid over a caster/ ball transfer.

Also, rivets can be a massive pain to remove, particularly if ther are lots of them in your design.

Re: first robot

i think il go with a skid then, i have some wood that i bought by mistake for my DT project in school, maybe it will be good to make a small frame out of.

Re: first robot

i have mounted the drill motors to the robot but when i turn the transmitter on one of the wheels just continuously spins. its not the first time i conected them up to the reciever, it worked perfectly last time.
anyone know what might be wrong?
EDIT: just reconnected everything again and it worked fine. im still using my dads transmitter from his rc car just to test it, i should be getting a new one by the end of the week.

Re: first robot

havnt got the transmitter yet, found you though that i need to get bigger wheels. im going to order the 100mm instead of the 75mm wheels next week.
