Title: Teleoperation principle design
Post by: misg on November 21, 2009, 04:00:24 AM

Hi,

I'm starting to be ready to make my first teleoperated robot, but I'm a bit overwhelmed and not quite sure how to start. I need to send the telemetry to my PC, so that I know how to control the robot with keyboard input etc. I was thinking of hooking a netbook to the robot and transmitting through it, but it seemed a bit overkill so could you give any hints/guides/tutorials of doing this in the old fashioned way?

Cheers

Hi,

Which oldfashioned way (wired/wireless)?
How much information do you need to convey and at what speed?
One way or two way?

A teleoperated vehicle can be as simple as an R/C-car, or quite complicated if you need a camera constantly showing you the view from the vehicles perspective (telepresence).

Wireless two-way (telemetry & control of the vehicle) communication. Initially I'll add just basic sensor input (conditions, tactile, velocity etc.) which shouldn't be more than few dozen kbs. If I would add a video link, how would it change the hardware demands?

Couldn't you just use a wireless camera?

How do I get the other telemetry data?

There are many RF solutions for uni or bi-direction data. SparkFun has a number of different TX/RX & transceivers available.
