Help out a novice in need!
Hi, My name is Jonathan. I was at the Reading robot club for the first time yesterday ( 06/06/2009) with my first robot Anti-depressant which won the best rookie award. It was great and I am now planning the build of another robot. Being new to the trade I am not sure what suppliers of robot parts are reliable and well stocked and am also unsure of what combinations of batteries, wheels, motors, servos, recievers etc. are advisable. Can you recommend an internet supplier and maybe some suggestion of what could go into a well built robot.

Hi Jonathan, I remember you from yesterday. All the top flight ants these days use Lipo batteries and micro geared motors, combined with speed controllers. Also, most antweight builders run there ants on a more advanced radio system: Spektrum/2.4GHZ. The main downside to using these more advanced components is the cost, as well as the wiring being more complex. If you don't want to move to motors, speed controllers, lipo's and spektrum, I would suggest: using speed modified servos for drive instead of standard modified servos, you could also change your 4.8v NiMH battery for a 6v one. You don't need a spektrum RC system to do well in the competitions, all my ants are running on 40mhz, and one of them (Terrior) reached the quarterfinals of AWS 28 and RRC 18. If you don't want to speed mod the servos, I reccommend the Supertec Parkflyer HPXF for drive, as it is fairly quick with a standard mod, and provides good torque. For a weapon servo I would use the park HPX, park HPXF or the HS82 MG. The best 40mhz reciever at the moment is the HFS-05MS.
Hope this helps,

Also, if you're using LiPos, remember that although the nominal voltage is 7.4v, they actually give 8.4v when they're fully charged. Consider building one of these.
