The UM6 ultra-miniature orientation sensor from CH Robotics uses rate gyros, accelerometers, magnetic sensors, and an onboard 32-bit ARM Cortex processor to estimate sensor orientation at 1000 Hz. Sensor orientation is reported using either quaternions or Euler angles over a TTL serial interface at user-customizable rates. The UM6 was designed specifically to be easy to use Ñ an external enclosure protects sensitive electronics, and connectors make it easy to interface with the sensor without making solder connections to the sensor itself. The CHR-UM6 was designed specifically to be simple to use: an external enclosure protects sensitive electronics, its small size (1.1" 1.4" 0.5") makes it easier to fit into the end system, and connectors mean no soldering to the sensor itself is required. A polarized four-pin male connector on the side of the UM6 matches an included 7.5" cable and provides the lines necessary to power the board and use the main TTL serial interface. Two 12-pin female connectors on the underside of the UM6 provide access to these same pins along with additional, unused Cortex pins and allow the sensor to be plugged directly into a host system, removing the need to run wires to enable the sensor to communicate. The UM6 can be configured to automatically transmit raw sensor data, processed sensor data, and angle estimates at user configurable rates ranging from 20 Hz to 300 Hz in roughly 1 Hz increments. Alternatively, the UM6 can operate in Òsilent mode,Ó where data is transmitted only when specific requests are received over the UART. Regardless of the transmission mode and rate, internal angle estimates are updated at 1000 Hz to improve accuracy. The UM6 simplifies integration by providing a number of automatic calibration routines, including rate gyro bias calibration, magnetometer hard and soft iron calibration, and accelerometer ÒzeroingÓ to compensate for sensor-platform misalignment. All calibration routines are triggered by sending simple commands over the serial interface. The UM6 comes factory-calibrated to remove soft and hard iron distortions present in the enclosure. When integrated into the end-user system, additional calibration may be necessary to correct other magnetic field distortions. Magnetometer calibration can be performed using the CH Robotics Serial Interface software.
