ActuatorMotors (UORB message)

Motor control message.

Normalised thrust setpoint for up to 12 motors. Published by the vehicle's allocation and consumed by the ESC protocol drivers e.g. PWM, DSHOT, UAVCAN.

TOPICS: actuator_motors

Fields

Name	Type	Unit [Frame]	Range/Enum	Description
timestamp	uint64	us		Time since system start
timestamp_sample	uint64	us		Sampling timestamp of the data this control response is based on
reversible_flags	uint16			Bitset indicating which motors are configured to be reversible
control	float32[12]		[-1 : 1]	Normalized thrust. where 1 means maximum positive thrust, -1 maximum negative (if not supported by the output, <0 maps to NaN). NaN maps to disarmed (stop the motors)

Constants

Name	Type	Value	Description
MESSAGE_VERSION	uint32	0
ACTUATOR_FUNCTION_MOTOR1	uint8	101
NUM_CONTROLS	uint8	12
