Hi,

I've got the same background as you there bud. I race RC cars and fly RC Helis.

I don't think you can us a standard 8CH TX with the receivers that come for the Kondo robots without some serious modification.

Standard TX for cars for example us pulse modulation to transmit positions of the sticks to control the servos directly; like steering or the throttle. The receivers on the Kondo kits expect 'input values' in the form of a digital number between the range of 1-65535 that in my exp are then assigned to gaits; not directly to servos themselves.

Not saying its impossible to do, but you can't do it out the box. Maybe it can be done with C api programming and some mods to the receiver but not through the current H2H stuff as I know.

There are a couple of receiver kits available for RC control. I've got the KRC-1 setup to control my KHR-1HV, it works well.

You can setup the gaits to walk if you keep your finger on 'foward' or you can make him walk 10 steps with just one push. Its in the programming of the gait more than the receiving of signals from the TX.

I've also seen a more modern controller on this site with an analog stick but I've not had any exp using it.

I’ve a newby question that I hope someone will answer for me, but first my limited knowledge base. I have been building and operation RC tanks, cars, trucks and motorcycles for years and that is all I know. I’m used to the usual combining of joystick movements in order to make a vehicle move, rather than programming movements and pressing buttons. Here’s is what I’m curious about:

Is it possible to take a robot kit like the Kondo KHR-2HV and use a standard ground transmitter with eight or ten channels to control it? I want to use joysticks to command direction and speed and use buttons and/or toggle switches to perform the computer programmed, preset moves. I guess what I’m trying to say is that I want to control as much as possible in the manner that I’m used to, and still have various moves/actions that can be performed at the touch of a button or the flick of a switch. I do not want to just press buttons on a transmitter that functions like a television remote or be tethered to a laptop computer. Of course, I don’t want to limit what my robot can do either, but I would like to control it like any other RC. Is that possible?

Please forgive my ignorance, but I just discovered robotics and I feel like I’m hooked before I even have a robot of my own or even a clue about how it all works. I plan to buy a Kondo KHR-2HV starter kit at the beginning of September, but from the videos I’ve seen I don’t know how the transmitter works as they are not the subject.

Thanks!
Jason
