Hello everyone!i m new to programing, i was wondering if any of you could help me with my robot.
· It's a 14x12 rover with tracks that i built and i would love to control it with my 2.4Ghz radio as well as having some sonsors on board.
Any help will be gratly appriciated.

    You need to learn programming and some simple exercises specific to robotics. Parallax has manuals and tutorial guides. If you don't have it already, make sure you have the BASIC Stamp Syntax and Reference Manual and the "What's a Microcontroller?" tutorial. Also helpful will be the Robotics with the BoeBot tutorial. Go to Parallax's main webpage and click on the Resources tab. You'll get a list of links. The Nuts and Volts Columns is one that you should browse when you have time. The Downloads link will get you another list. The Stamp Documentation link will get you to a copy of the Stamp Manual. The Stamps in Class Downloads link will get you a listing of almost all of the Parallax Tutorials. The Robotics one is a good starting point, but some of the others may be useful eventually. For Parallax products, the webstore pages have links to documentation and sample code for the product. You didn't say what sort of motor controller you have or what kind of wireless link you're using. If they're not Parallax products, you may be able to find something similar from Parallax where you can start with Parallax's sample code and modify it for your equipment.

    i have (2) 12vdc 225 RPM motors,the motor controller is the dimension engineering sabertooth·2x25.

    The Dimension Engineering controller has an R/C mode which make it look like two servo motors. Any of the Parallax documentation that shows how to control servo motors (or their HB-25 motor controller) should work much the same with your controller. Be sure to read the Dimension Engineering documentation carefully in case they have some special features that are different. They also have two serial modes and the Stamps should work fine that way either at 2400 Baud or at 9600 Baud using the SEROUT statement as described in the Stamp manual. The Stamps have +5V logic TTL signals and should be able to be connected directly to the motor controller. On general principles, it's usually a good idea to put a 220 Ohm resistor in series with the Stamp I/O pins when connecting to another controller unless there's a particular reason for not doing this. It's possible to accidentally program an I/O pin as an output when it should be an input. If the other device is set to the opposite output state, you can damage one or both devices. The 220 Ohm resistor limits the fault current to protect both devices.

    I'm thinking of controlling the rover semi-autonomously by using my 5-channel R/C radio and the sensors on board so,if it runs into objects it may alert· me and or search for another path to go to.
