What are some thoughts and suggestions on building an electronically controlled go-kart/dune buggy? Answered

 Hello. I plan on building a go-kart that is completely electronically controlled. Basically I want to to be able to be controlled remotely but I will be riding in it. I will make sure to buy a kart with an automatic transmission and hydraulic disc brakes. Also I figure about a 200-300cc engine. I would expect the throttle and braking to be fairly simple. Steering not so much. Does any one have suggestions on how to get started and what parts I might need? Any help would be appreciated..

It's going to be much harder than you expect.  Since you won't have any sensory feedback when controlling remotely, you're going to over correct on the steering and braking and acceleration.  

You can use regular rc car radio equipment but you're going to have to build your own actuators.  I don't think you can get servos large enough.

If you can find back episodes of "Myth Busters", there were several of them where they build a remotlely controlled car using rc transmitter and receiver and linear and rotary acuators that they bought or built.  It would be worth you time to look at them.  They give lots of details.

It bears mentioning that even Jamie & Adam have trouble controlling their RC vehicles. I don't think they've had one build yet that they didn't crash into something, including one memorable one where Adam was in the car at the time. Live cargo would make me very nervous, even if there was a kill switch (and there should be a kill switch).

 Good call about a kill switch. Safety is a concern of mine. Also,i t does not necessarily need to be controlled remotely. The controls could be hardwired. I used RC to indicate the level of modification.

Sounds like it could be very cool. There's a little bit of drive-by-wire info in this instructable:

but it's kind of incomplete, so you may not get much that you're looking for out of it. When you build yours, be sure to take lots of pictures and make an 'ible. I'm sure lots of people would appreciate it.
