Help with a Gyro
I would like to know the possibilities of installing a Gyro in a robot car. The wheel base is 20" and the track is 18" the speed is 2-4 mph.·Using front wheel steering and a steering angle of +40 to -40 degrees in 1 second
My question is, would it help the straight line performance and where to install the gyro. I have been looking at and I wonder or this gyro·would do the job··(GU-210 heading hold).·Thanks Hank

What you really want is an accelerometer.

Never used them, but after looking through the info, you are on the right track. The one you were looking at is an rc type, have a look at sparkfun. com for their gyro breakout board selection. Most just output a differential voltage , which could be read with your stamp. I was wondering about vibration, but it seems that has been accounted for.

When you HIJACK a thread like THIS, it makes it DIFFICULT to FIND YOUR MESSAGE!!
You were probably looking in the wrong places, here is a link to the Parallax web pages with ALL the Stamp Software which has to do with programming. Linux IS among those listed, BUT it is NOT SUPPORTED by Parallax. It was written by an OUTSIDE AUTHOR. Here is the link: http://www.parallax.com/tabid/441/Default.aspx

When all else fails, try inserting a new battery.
In the future please post questions not related to the current discussion in a new thread/post. Had you not received a reply this message would have been removed. It is always easier to help someone when the subject of the message is clear. When you post in someone else’s unrelated thread this isn’t the case. Take care.

Kevin, you might want to look at the links, your post is not accurate. The difference between gyros and accelerometers has nothing to do with the x,y and z axis, which are arbitrarily assigned by humans. The difference has to do with rotation and the force of gravity.
An accelerometer measures acceleration. A 3-axis accelerometer will tell you the orientation of a stationary platform relative to earths surface.
A gyro measures rate of rotation around a particular axis.
