AWINDA
AWINDA
Awinda is the name of the patented wireless radio protocol used by Xsens to transmit data from its motion sensors without cables.
The associated product, MTw Awinda, is a 3D inertial-magnetic tracker.
In practical terms, the sensors are attached to the body (using straps, harnesses, etc.) and transmit the orientation and movement of each body segment in real time to a receiver connected to a computer.
Components and characteristics
- Sensors (MTw trackers): each MTw unit is a complete inertial magnetic unit (IMU) containing:
- a 3-axis accelerometer
- a 3-axis gyroscope
- a 3-axis magnetometer
- a barometer
- an internal temperature sensor (thermistor) — used to compensate for the effects of temperature on the other sensors.
- Internal battery: a rechargeable LiPo battery. Depending on the version: typical battery life of approximately 6 hours in continuous use
- Receiver unit/base station (Awinda Station):
- An “Awinda Station” — complete base: it receives data from several MTw units, synchronizes the signals, and powers/charges the sensors.
