Motion capture

Acceleros & Gyros

The heart of the system is an inertial system using 3 accelerometers and 3 gyrometers. We can measure acceleration from almost zero (smallest vibrations) to 16G (biggest impacts).

AHRS

To dynamically orientate the bike, we’ve built an AHRS (Attitude and Heading Reference System). Commonly used in the aerospace industry, this system is able to track the angular position of the bike: Pitch, Yaw and Roll.

Baro, Magnetos & GPS

In addition, we use other sensors to give us more information about the trajectory of the bike: a barometer and magnetometer in the device, and the GPS in the Smartphone.

Battery

Li-ion 14500 battery has one of the best energy densities. Rechargeable using to a waterproof micro USB. It has 100h autonomy.

Task distrbution

All the energy demanding processes are carried out by the smartphone’s powerful processor, helping to maximize the device’s battery life.

100Hz

All data are updated one hundred times per second.

RAW to MOVES

Raw numbers can be monitored for computing. But for the every day ride, we’ve build in some automatic post-processing. see Experience.

Updates

With a simple update of the app we can upgrade whole system.
