Is Program Running
SUMMARY
Is Program Running returns True if a program is currently executing on the robot controller and False otherwise.
SUPPORTED ROBOTS
Currently supported only on Universal Robots.
UNITS
Returns a boolean. No quantitative units.
The Skill
python
running = robot.is_program_running_on_controller()The Code
Example: Check Whether a Controller Program Is Running
Connect to the robot and check whether a program is currently executing on the controller.
python
from loguru import logger
from telekinesis.synapse.robots.manipulators import universal_robots
robot_ip = "192.168.1.2" # replace with your robot's IP
robot = universal_robots.UniversalRobotsUR10E()
# Connect
robot.connect(ip=robot_ip)
running = robot.is_program_running_on_controller()
if running:
logger.warning("A controller program is currently running.")
else:
logger.success("No controller program is running.")
# Disconnect
robot.disconnect()The Explanation of the Code
For Universal Robots, is_program_running_on_controller reads the runtime_state RTDE field and maps it to a boolean. A return value of True means the controller is actively executing a URScript or teach-pendant program. Use this to detect conflicts between externally commanded Python motion and controller-side programs.
How to Tune the Parameters
This skill takes no input parameters.
Return Value
| Field | Type | Description |
|---|---|---|
running | bool | True if a controller program is running, False otherwise. |
Where to Use the Skill
- Startup checks to confirm no program is running before issuing Python-side motion commands.
- Orchestrating hand-off between controller programs and Python control.
When Not to Use the Skill
Use a different skill when:
- You need to distinguish between paused, stopping, and stopped states - use Get Runtime State for the full state code instead.
