Russian Researchers Develop Algorithm to Boost Accuracy of Medical Robots
A new algorithm created by Russian engineers helps robotic manipulators avoid collisions and perform delicate lab tasks with sub-millimeter precision.
Engineers from three Russian universities have unveiled a new algorithm that enables robotic systems used in medical labs to operate in tight spaces without failure or collision. The system demonstrated high precision, with manipulator deviations of no more than a millimeter.
Modern medical labs often rely on multi-arm robotic setups to handle tasks like tube sorting and liquid dosing. However, coordinating the movements of multiple manipulators has long been a challenge. The Russian team took a different approach — their algorithm pre-calculates safe movement trajectories, creating predefined no-collision zones.
In virtual tests, two robotic arms — one handling fluid dosing, the other managing test tubes — worked in perfect sync. The horizontal deviation was under 1 mm, and the vertical error was less than 0.2 mm.
What sets the system apart is its adaptive design. It automatically adjusts paths based on the workload of each manipulator, speeding up task execution and reducing idle time.
