3D Accelerometer
for RP6 Robot, but also useable for RP6 WIFI, ARUDINO
and ASURO
and ASURO
Introduction:
General purpose 3D accelerometer module for robots. This 3D accelerometer can
determine the absolute angle of your robot, e.g. Roll and Pitch value can be easily
calculated by a microcontroller. In addition you can calculate the vector of a collision
impulse. This information can be used to move around an obstacle.

Hint: Often, the differences between a Gyro and an Accelerometer is not clear and
got mixed up.

Here a clarification:
A gyroscope is very good in finding the rate of an angular change, but
can’t detect an
absolute angle
– but an accelerometer does!
