Low Cost Gyro-Accelerometer Sensor

Posted 23 Jan 2003 at 13:37 UTC by steve Share This

Earl Bollinger of the DPRG has written an article describing the construction of a low-cost combination gyroscope and accelerometer sensor. The sensor is based on the Analog Devices MEMS-based ADXRS150 piezo-gyroscope and ADXL202 accelerometer chips. This type of sensor is commonly used in one or two wheel balancing robots and flying robots. The article includes schematics, PC board artwork, component lists, and photos.

Most useful.. Those DPRG guys are tops., posted 24 Jan 2003 at 19:06 UTC by Jhoffa_ » (Journeyer)

This is a great article Steve, thanks for posting it.

I think it's great that people take the time to review these things and save others money and trouble. Now anybody with a PIC micro and about a hundred bucks can have their own balancing, Segway type robot.

That's what I love about this place, there's so many good ideas show cased here.

Along these same lines, here: is a link to "Nbot" a two wheeled, balancing robot using the same technology.

Thank you very much,

We beat you to it, we did put in a link reference to NBOT at the bottom of the article. Along with links to a couple of other pertinent sites as well.

Ohh! You wrote that..., posted 25 Jan 2003 at 17:59 UTC by Jhoffa_ » (Journeyer)

I didn't know the author was here on Robots Dot Net.

It is good, I love things that take the complex and make them understandable.. So many people who do things like this make it over complicated to the point that beginners are swamped.. I am really glad you made it as plain and easy to understand as you did. A bunch of people are going to benefit from this.

I just absolutely must have a balancing robot now. Definitely my next project.

Thanks again!
