AbbClient

class compas_rrc.AbbClient(ros, namespace='/rob1')[source]

Bases: object

Client used to communicate with ABB robots via ROS.

This client handles all communication over ROS topics, and implements blocking behaviors as an application-level construct.

Examples

Connection example to a single robot:

# Create Ros Client
ros = rrc.RosClient()
ros.run()

# Create ABB Client
abb = rrc.AbbClient(ros, '/rob1')
print('Connected.')

# Close client
ros.close()
ros.terminate()

Advance connection example to multiple robots:

# Create Ros Client
ros = rrc.RosClient()
ros.run()

# Create ABB Clients
abb_rob1 = rrc.AbbClient(ros, '/rob1')
abb_rob2 = rrc.AbbClient(ros, '/rob2')

# Clients are connected
print('Connected.')

# Print Text
abb_rob1.send(rrc.PrintText('Hello Robot 1'))
abb_rob2.send(rrc.PrintText('Hello Robot 2'))

# Close client
ros.close()
ros.terminate()

feedback_callback(message)	Internal method.
send(instruction)	Sends an instruction to the robot without waiting.
send_and_subscribe(instruction, callback)	Send instruction and activate a service on the robot to stream feedback at a regular inverval.
