Syntax

jointangles=getJointConfiguration(ur)
jointangles=getJointConfiguration(ur,timeout)

Description

jointangles=getJointConfiguration(ur) waits for the next published joint state from the Universal Robots cobot connected through ROS interface, and returns current joint configuration. If no message is received in 5 seconds, the function displays an error.

jointangles=getJointConfiguration(ur,timeout) allows you to specify a timeout for obtaining the current joint configuration from the Universal Robots cobot connected through ROS interface. If no message is received within the specified time, the function displays an error.

example

Examples

collapse all

Connect to a physical or simulated cobot, using either urROSNode or urROS2Node object (based on the option for connectivity – ROS or ROS 2, which you selected in the Hardware Setup screen).

  • Connect to a physical or simulated cobot at IP address 192.168.2.112 on the ROS network.

    ur = urROSNode('192.168.2.112');

  • Connect to a physical or simulated cobot on the ROS 2 network.

    ur = urROS2Node;

Get current joint configuration of the cobot.

jointangles = getJointConfiguration(ur);
jointAngles = 1×6    
    0.0001   -1.9552    1.6748   -2.5979   -0.0001    0.2542

Specify a timeout of 10 seconds while obtaining current joint configuration of the cobot.

jointangles = getJointConfiguration(ur,10);

Input Arguments

collapse all

Connection to physical or simulated cobot from Universal Robots, specified as a urROSNode object or a urROS2Node object.

Timeout value by which the joint configuration must be obtained from the simulated cobot, specified in seconds.

Data Types: double

Output Arguments

collapse all

Current joint configuration, returned as a 1-by-6 vector of angles in radians.

Data Types: char
