Motion range

Joint name Motion Range (degrees) Range (radians)
HeadYaw Head joint twist (Z) -119.5 to 119.5 -2.0857 to 2.0857
HeadPitch Head joint front and back (Y) -38.5 to 29.5 -0.6720 to 0.5149

Access value by using ALMemory key name

Command(radians):

Device/SubDeviceList/HeadPitch/Position/Actuator/Value
Device/SubDeviceList/HeadYaw/Position/Actuator/Value

Sensor(radians):

Device/SubDeviceList/HeadPitch/Position/Sensor/Value
Device/SubDeviceList/HeadYaw/Position/Sensor/Value

Anti collision limitation

Due to potential shell collision at the head level, the Pitch motion range is limited according to the Yaw value.
