Many robotics applications have real-time requirements, which means that they must be able to execute sections of code within a strict deadline. A control loop is one such example - failure to complete the control loop in time may cause controller instability or trigger protective stops! For ROS applications, ros2_control is a framework that can be used for real-time control of robots using ROS 2. Whether writing a real-time application with ros2_control, or your own custom real-time application, real-time code requires a specific set of concerns around ensuring latency is controlled and deadlines are met.

In this blog post, we’re going to discuss priority inversion, which is a potential source of unbounded latency that needs to be avoided in your real-time code. Priority inversion is very much a concern for robotics: a famous example is that priority inversion caused a failure on the Mars Pathfinder!

πŸ”– Topics: Funding Event

🏒 Organizations: PickNik Robotics, Stellar Ventures, Cypress Growth Capital


PickNik Robotics Inc., a Boulder-based developer of a robotic-arm technology platform, recently completed a $2 million pre-seed investment campaign led by Stellar Ventures and Cypress Growth Capital.

The company’s MoveIt Studio is a robotic manipulator interface software that enables human operators to do more complex tasks. The platform can operate in a broad range of unstructured and high-latency environments such as urban areas, inside buildings, microgravity, and subsea. Applications range from bomb disposal to the sorting of objects in space.
