looking for two 6D sensor
 

I'm a software guy and thus the quest below might seem trivial to you.

Looking for two 6D(pitch, yaw, roll, x, y, z) sensors.

The desired properties of each of the two sensors are:

range: ±2g; 400°/s
stability: 1mm/h, 0.5mm/°C; 0.5°/h, 0.25°/°C
resolution: 0.1mm; 0.01°
sampling sequence: 100 Hz
shock: 5g for 10ms
temperature: -20°C ... +50°C
max dimensions: sphere with radius 4cm; 80g
output/power supply: USB or wireless with

The physical dimensions and power/data connection aren't yet set in stone.

Any idea who is producing/selling this kind of sensors and what their price range is?

Thanks for any suggestions,

Thomas

you can try www.globalspec.com. This is a good engineering search engine for all things to do with engineering.

Well, sparkfun does have some stuff that is relatively reasonable and close to your specifications, though the wireless and 400 degrees per second will be difficult to get I think. But contact them, they may be able to work with you.

Actually spark fun is producing an wireless IMU (inertial measurement unit) that is 6DOF like you want, it uses bluetooth or you can get the serial data out of it with the debug header, i am trying to use one now with an robotics project at school. Here is the link to itIMU/Gyros

powered by 6v and outputs TTL I do belive
We got the V2 FYI

On your specs you listed the drift or lack of it that you wanted, I think this is mostly a facotr of your software and the integration, you may be able to find an absolute gyro / accelerometer but the vast majority of affordable ones simply output acceleration in whatever axis, not position, you may want to check out how kevin watson does it with his gyro code Kevins site in his first robotics section there is some really well commented code and readme's in the files

I also like the Sparkfun product line. But remember: Although a lot of fun to play with, any wireless devices are not allowed on the robot.

Have you looked into hacking a Gyropoint mouse? It's wireless, and the data comes out in a well documented useable format.
