Microrobot’s self-correcting design sets new standard for microsurgery

Precision in microsurgery is critical. Just a few microns can dictate success or failure. Traditional robotic surgery tools rely on external cameras and sensors, which can be bulky and limited in tight surgical spaces.

A breakthrough microrobot developed by researchers combines internal vision and a self-correcting mechanism to achieve micron-level accuracy deep inside the body. This advancement reduces reliance on external systems and pushes surgical precision to new heights.

How does the microrobot achieve such high precision?

The microrobot uses advanced piezoelectric actuators for quick movement and flexible structures inspired by origami, enabling it to operate smoothly.

It uses a miniature embedded camera, creating a closed feedback loop to monitor and correct its position in real time.

This design minimizes drift and hysteresis common in traditional actuators, delivering remarkable motion control within 8 microns of accuracy, smaller than the width of human hair.

What advantages does internal vision provide in microsurgery?

Internal vision eliminates the need for bulky external cameras, reducing equipment footprint and interference in surgical environments. It also increases reliability by providing direct visual feedback from the tool itself.

Such an onboard system enhances stable, responsive control in sterile, confined, and electromagnetically noisy environments where external sensors may fail, enabling more complex and precise surgical procedures.
