parallax

Hello all,

I am completely new to robots and it seems like it's gonna be a lot of fun.  I am in a college class right now with a project of designing a robot.  Here is what I know:  We are using parallax microcontroller (I think... Board of Education Rev C), and I have gotten familar with the basic terminollogy.  My team plans on making a simple bot like the start here version, except bigger, with tracks, a nice cover, and some lights.  However, we really want to incorporate some audio clips and music...

I have an Inex POP-BOT which came with an arduino-like microchip, and was thinking of getting a BOE-BOT, which uses a Board of Education with a BASIC stamp microchip attached to it. Now my question is, there two chips seem to look identical in size, and can both be detached from their respective developer boards, so what I'm wondering is, would they be interchangeable?

I've found an awesome rotary encoder (I believe it was the smallest on Rootshop) but I have no idea how to use it? I believe there's an input, a ground and a signal pin, but I don't know how to configure it or anything. I'm going to be using it with an arduino.

I've digged the web and have found no documentation. Just sayin

Thanks ;)

Hi

I'm new to this forum and i would like to know a few things.

Which one of the following ultrasonic rangefinders do you prefer.

I know that the ez module is designed for indoor environments but i would like to use my robot outdoors

as well,do the ping and the srf05 would outdoors as well.

My robot is going to be a basic obstacle avoiding robot for otudoor and indoor use.

I know the ez is accurate to about 1 inch,what about the accuracies ofthe srf05 and ping but this is really not going to

As of this morning, roboteers who use the Parallax MSR1 (Robot Controll Board) in their robots and use the built in motor ports can now use 12Blocks to directly drive their robot.

It uses a modified version of the SRMotorControl Object found in the Parallax Object Exchange (slight modifications to accommodate the 12Blocks motor protocols

There is a new hardware profile called Stingray (May change to MSR1) available from your 12Blocks screen. When saved to RAM or EEPROM, The drivers are loaded into your robot and away it goes.

I'm using the PSC to control 4 servos of a robotic arm. 2 switches are used to select the 2 default positions.

When a switch is activated, the servos do not respond. They only do after the reset button on the PSC is pressed.

I'm wondering is it possible to write a code to reset the PSC instead of doing it manually.

Anyone done it before?

Ok, so I finally got all my gear set up to build robot numero uno, but Im goin friggin nuts trying to control my continuous rotation servos from parallax. Im using a picaxe 18x to produce the code, but no matter what pulsout or servo commands I use, my servo's only go clockwise.I NEED them to be able to go counterclockwise  for my differential drive train to work right. I have read every post on LMR about servos and have tried a lot. I have read their parallax data sheet and that they should respond based upon the pulse width, but no go.
