A Guide To using IMU (Accelerometer and Gyroscope Devices

Dec 29, 2009· In C implementation, to avoid unnecessary conversion, I think to get the tilt of accelerometer it will be better to just stick with ADCRx – 512 (using 10 bit adc) to get the angle, at 3.3V input at the accelerometer, the typical 0deg position will be 1.65 which will yield also 512 in a 3.3V vref, a greater than 512 value means tilt angle at the 1st quadrant then a less than 512 …

The Controlled Human Gyroscope

The Human Gyroscope Motion Simulator rotates a human about three axes of motion with a coined g- force of at least 0.2 G’s. Safety is a major concern, so the materials selected needed to be strong, rigid but at the same time lightweight. For the rings of the gyroscope, tubes were chosen instead of solid stock in order to save weight.

Clean bearings mean longer life - Environmental Engineering

Typically, a bearing for a gyroscope has a bore diameter of around 5mm. Two bearings are normally required – one on each end of the rotor shaft in a back-to-back configuration. Another key requirement is that the gyroscope operates with low noise levels. The bearings are therefore fitted to the system and bench tested.
