Summary
SDATA 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

| LARRAY 0 | UINT8 | Length of array (0-255) |
| PREFIX 0 | INT8 | SI-prefix (-127 - 128) (see bellow) |
| DIMENSION 0 | UINT8[6] | Dimension (see bellow) |
| ... | ||
| FORMAT (NSENSORS-1) | ||
| LARRAY (NSENSORS-1) | UINT8 | Length of array (0-255) |
| PREFIX (NSENSORS-1) | INT8 | SI-prefix (-127 - 128) (see bellow) |

| DATA | ||
| DATA 0 | float64[LARRAY 0] | value array for sensor 0 |
| DATA 1 | float64[LARRAY 1] | value array for sensor 1 |

| DATA (NSENSORS-1) | float64[LARRAY (NSENSORS-1)] | value array for sensor (NSENSORS-1) |
Definition of PREFIX and DIMENSION fields
The PREFIX and DIMENSION fields are used to specify units. The PREFIX fields is an exponent representing SI prefix (e.g. milli, micro, nano, kilo, ...), while DIMENSIONS is combination of SI base units and/or SI-delived units.
