Can anyone advise me on where I can get off-the-shelf components that will do the following:
I have a robotic vehicle whose motion is controlled by an on-board controller that responds to an input from two on/off switches and a pair of voltages that vary continuously from one volt up to 3.4 volts. Currently, I generate these signals programmatically on a signal synthesis and acquisition Board (LabJack U12) that is connected to the USB port of my desktop computer. I would like to untether the vehicle from my desktop computer. Does anyone know of electronic components I can use to wirelessly generate these signals on my vehicle? (For example, are there radio controlled potentiometers that I could control from my computer?)
Regards,
Joe
Spark fun electronics sells a range of wirless transievers. One is the Blue smirf which is a wirless serial port.
Hi,
And then couple the serial I/O to a small PIC board, like the UBW I’ve mentioned on other threads. Then use a D/A chip off of some of the port lines to give you the analog you want, and a few on/off signals (digital) as well.

If you get a wireless serial device, you could get a digital to analog chip like below and connect it to a ssc32 or to a serial to parallel chip like the bottom one.
