Gyros vs. tilt

2007-12-04T01:11:50+01:00

Can you use tilt sensors to do the same thing as gyros, such as forward/bakward stability?

Thanks, I appreciate the help. Is there any where I can get a tilt sensor around here an maybe avoid the over the pond ordreing?

Gyros vs. tilt

2007-12-02T04:08:51+01:00

The PG-03 gyros sense only the initial change in momentum (a push or pull). If your robot is static (say, tilted forward w/o any change in degree), no copensation will be processed. The harder the push or pull, the greater the reaction (typically in the leg and/or knee servos). Because of the way they're set up, enabled gyros tend to make the robots "fish-out" while flipping or falling on their face/back. They do not trigger a routine to stand.

With a tilt sensor, the value sent is referenced from the constant pull of gravity perpendicular to the ground. If your robot is tilted forward and static, the sensor is still aware it's tilted at an angle. So if he's on his stomach, you can trigger a routine to return him to an upright position.

Having both is nice.

Gyros vs. tilt

2007-11-30T23:30:04+01:00

Hi folks!! I am right now putting together hip servos in my nova and looking at the two pg-03 gyros that are next, I read the article an it looked like a needed item. can I set the sensitivity to recognize when he has fallen say 30 - 50%. also do the gyros affect commands like cartwheel, tumble? Will I need to gyro-off for these moves? I know from reading in these forums the tilt sensor preforms the same kind of function but with a lot less sensitivity....do I still need it or can I fall back on the gyro for this? any help would be appreciated since I'm new to all this.
