Summary
SENSOR is a message type, which is used to transfer sensor reading, 3-axis position, velocity, acceleration, angle, angle velocity and angle acceleration. The message format is intended for manipulator control and various types of sensors.
Message Types
SENSOR
| Data | Type | Description |
| LARRAY | uint8 | Length of array (0-255) |
| STATUS | uint8 | Sensor status (Reserved) |
| UNIT | uint64 | See 64-bit UNIT field. |
| DATA | float64[LARRAY] | value array for sensor 0 |
Examples
Sending 3-axis troque
A device with 3-axis torque (N*m) sensor is sending data to a data logger program. The following table shows example data format to send 3-axis torque:
| Data | Type | Value |
| LARRAY | uint8 | 3 |
| STATUS | uint8 | 0 |
| UNIT | uint64 | 00000010 11000000 00010000 00000000 00000000 00000000 00000000 00000000 |
| DATA | double[3] | {0.0, 0.0, 0.0} |
Sending 3-axis force, troque and acceleration
By binding SENSOR data using BIND type, values from multiple types of sensors can be transferred simultaneously. See BIND message description page for detail.
