RTOS for Safety Critical Systems

Designing the right RTOS architecture requires delicate attention and decisions. Basic real-time operating system services such as inter-process communication, process synchronization, process management and interrupt handling must unfold efficiently.

How to Design a Real-Time Operating System (RTOS)

Real-time operating systems rely on kernel designs to expedite process communication and synchronization functionalities.

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
