Seems to me that by using 2 motors for propulsion and steering would be the quickest and most simple way to create a line follower. I actually used 2 full rotation servos for my line bot. I used a camera and vision processing for feedback so it had to go a little slower, the servos suited it well.

Check out R/C car pinion and sprockets. They are much cheaper than many of the previous sources listed.

There are many different ways to go about wireless control so thats why I was asking you to tell me more info. Anyway you can go with something simple like a standard r/c transmitter and use servos and motors. You can buy wireless rs232 modules and couple them with an MCU if you want to go more of a...

Your post is very vague. You give almost no info on your robot so it will be hard to point you in the right direction.

You will need to build a host controller. Microchip has chips that are setup for devices but not controllers.

Servo controller web interface

Hello, I recently built a web interface for one of my servo controllers. It is open source. It is set to work on port 81 by default and the project was created using C++ .NET 2005. I set it up to work with my own servo controller so if you want to use another type you must have an API or add some se...

Sorry I have never used anything other than C for mcu programming but I can give you some C code that I am using that may help you get started. C0 is a digital line setup for input. The code was running on a PIC18f4550. int pinHigh(void) { if (PORTCbits.RC0 != 0) { return 1; } else { return 0; } } /...

I would start off by breaking the project down into two parts. I did something very similar to what you are doing. First, you need to create a PWM reader. This would, as you said, monitor the R/C receivers servo output. You can do this by looking at a digital input for when the signal goes high, the...

Open source servo sequencer

Hello, I have posted the source code for a new open source servo sequencer project that I just started. Currently operation is simple and it only has basic functions but it does work. The sample will only drive one servo but controlling more is as simple as creating another sequencer object. It was ...

If the PC does the thinking, is the "robot" really a robot? I think it's just a glorified sensor on wheels. But the brains on the wheels, then you've got yourself a robot. My mistake, I guess the proper word would be tele-autonomous. When I think of an autonomous robot, I think of it being able to ...

pc-to-rc July 2004

Hello,

Im interested in an article on how to build an interface to allow computer control of an r/c transmitter in the July 2004 issue. I do not have this issue and it will be $11 if ordered. Can anyone do me a favor if they have this and scan it in for me?

Thanks!
