CAN Communication

Baud-Rate

The CAN communication baud-rate is 1Mbps.

Non-Periodic Communication

Messages can be sent to initialize or stop CAN communication.
Remote frame can be used to request data. If host sends remote frame, the Allegro Hand responds with it regardless periodic communication status.

Periodic Communication

The Allegro Hand control software attempts to communicate with the real or simulated hand at a regular control interval. Every 3 milliseconds, the joint torques are calculated and the joint angles are updated.

CAN Frames

Arbitration Identifier

The Allegro Hand uses 11 bit standard arbitration identifier. It is composed with two part.

MSB 9 8 7 6 5 4 3 2 1 LSB
Message ID Device ID
