Re: Sumo Bots B/C [Trial]
The thing i like about bridge/towers/balsa events in general being expensive is, im learning something with each structure i build, and it's honestly fun to build - Nothing is wasted. With this event, i may (probably will) end up spending more even and end up with parts that i can't for some reason use, or find out i could have spent way less...

Dude the explorer is completely useless for sumo bots, an insignificant waste of money.

Re: Sumo Bots B/C [Trial]
Well, you're also pointing out the cost of the event while commenting on the discontinuation of a Vex product. There's more than one axis of ironic beauty to that statement.

i see what your saying but overall, cost is high. plus desiging a turning system. when you use a vex transmitter and reciver, your stuck having to use vex products which will bring up costs. other brands like futuba, and other ones are cheaper and all work well with each other. the only problem with that is the changing of channnels.

Re: Sumo Bots B/C [Trial]
It is possible to use a vex transmitter and receiver, but use completely different motors and stuff. Not that I recommend it. Pretty much any Hitec or Futaba set will be cheaper than and just as functional as Vex. Or you could just harvest some brains from a cheap RC car, if cost is really an issue. As long as it has multiple channels.
About channels: The old Futaba set I have now allows you to switch the crystals on both the transmitter and the reciever. I think the more modern non-bluetooth ones come in two categories: ones where you have to switch out a whole frequency "module" on the transmitter, and ones where the transmitter has multiple settings internal to it. If you get a bluetooth one, you probably won't have to worry, because most of them do automatic open-channel-seeking.

doesnt each part of robot operate on a channnel? like turning takes a channnel and driving the wheels take another channel?
then how would u change out frequencies?

Re: Sumo Bots B/C [Trial]
Ok, there are 2 definitions of the word channel, in terms of radio control. The one I was using is a specific frequency within a frequency band. For example, in the 75 MHz band, channel 70 is 75.590 MHz. The other definition is the number of signals that can be transmitted or received simultaneously. For example, you might buy a 4-channel transmitter.

Re: Sumo Bots B/C [Trial]
Each channel of control is encoded into one signal and sent over the radio link to the receiver, where it's decoded and broken up into separate PWM signal channels which can run servos, motor controllers, etc.
The "channel" of the radio link is another term entirely. The radio spectrum is broken up into usable, regulated bands, and those bands have defined channels within them. Transmitting on different channels is supposed to allow independent communication.
FYI, there are no Bluetooth RC sets. There are radio sets that have keying, modulation, and encoding schemes proprietary to a company, which happen to operate on the same US 2.4GHz band, and can pair Tx/Rx pairs that allow them to frequency hop or adjust for interference. But they don't use any part of the Bluetooth protocol and wouldn't be close to being able to operate with another Bluetooth device.
