I just built the starter kit robot with success, however I don't think that I'm just going to be able to build robots from scratch now. Are there any intermediate kits I can buy that use picaxe and arduino? Any suggestions would be appreciated.
I agree with Maxhirez. There are some great kits designed by LMRians. Check them out before you decide anything.
frankly if youve managed to build the SHR i think you are in the perfect position to build your own robot - its just a case of making sure you dont aim TOO high - eg an SHR with tank tracks or ultrasonic rather than IR detection.
good luck whatever you chose
