Gyro

ROB3, my third robot started out using my ROB1 base, as I wanted to play around with the gyro again using a 2 wheeled robot, but alas, one of the servos died. So … Read more

GY-521 and motion in a straight line

Hello all

I have a few questions about using GY-521 MPU-6050 gyro. If you have experience - please, help. 

1) Different sources indicate different allowable voltage - 3.3V or 3.3 / 5V. Can I use it with my 5V Arduino?

2) Is GY-521 enought for motion in a straight line of such platforms as dagu 4wd/6wd wild thumper?

Many thanks in advance.

gyroscope source recommendations?

Hi all, searching the site didn't give me much on gyros aside from the MEMS gyro sensors.  I'm interested in good old fashioned spinning chunks of metal :-).  I guess these could also be called flywheels, though ultimately I'm aiming for a gimbal mount active gyro.  Anyone work much with them in robotics projects?  

I'm designing a robot and trying to get a handle how much help they can provide to balance something tall and heavy... e.g. if I use a 20lb gyro at X RPM how much torque could it provide, etc.

FreeBOT (work in progress)

Project

FreeBOT - Is a Biped robot designed in Google Sketchup and printed out on a 3d print. My aim is to make it Free to everyone to print and improve. Since I can't afford a NAO.. this was the next best thing :-)
