Do not buy the KRG-1 gyros. They were designed for the original KHR-1 robot 4+ years ago. You can make them work with the KHR-2HV, but won't get the full benefit.

The KRG-3 gyros are correct for the KHR-2HV and 1HV. You need two. Please read the documentation before trying to install them. Actually, it would be best to study it before you make your purchase.

As far as the accelerometer goes, its primary purpose is to determine if the robot has fallen down, and which way it is facing down. You setup a set of sensor interrupts to trigger motions so that the robot can automatically stand back up. The RAS-2 is the correct accelerometer for the KHR-2HV. The older RAS-1 can be made to work, if you happen to have one handy, but beware that the connector orientation is different as well as the signal levels.

so I am buying my khr-2hv in a few days and I am still trying to figure out do I need two gyros??? Also just one accelerator I assume??? Thanks so much...

You need to sense 2 axises with both a gyro and a accelerometer. So get 2 one axis gyros, and 2 one axis accelerometers. So buy 2 KRG-1, and 1 KGR-2.

KGR-1:

It can take a week to get a reply sometimes. Views are also counted from nonregistered users, plus all members don't know the answer to every question posted here (I sure don't) so the best way to see if we can help is to look and see.
