Scientists at Nanyang Technological University (NTU) Singapore have developed a seed-sized surgical robot capable of navigating tight internal bodily spaces [1].
This technology represents a shift toward minimally invasive medicine, potentially reducing the need for large incisions and lowering recovery times for patients. By operating wirelessly, the robot allows for precision interventions in areas previously difficult for surgeons to reach.
The development team, which includes Associate Professor Lum Guo Zhan and PhD student Nicholas Foo, created a device approximately the size of a seed [1]. The robot is designed to travel through narrow corridors within the body to perform targeted therapeutic actions [2].
Researchers said the robot can perform five distinct surgical functions [3]. These capabilities include cutting tissue, delivering drugs, and collecting biological samples [2]. The device can also generate heat for cancer treatment and is capable of switching between these tools in under one second [3].
This versatility allows a single small device to handle multiple stages of a procedure without requiring the insertion of several different instruments. The wireless operation ensures that the robot can be guided precisely to a site of pathology—such as a tumor or a blocked vessel—without the constraints of physical tethers [2].
The announcement of the technology was reported on May 26, 2026 [2]. The team at NTU Singapore focused on ensuring the robot could maintain stability and functionality despite its diminutive scale [1].
“The robot can perform five distinct surgical functions”
The integration of multi-functional tools into a seed-sized form factor addresses a primary limitation of micro-robotics: the trade-off between size and utility. By enabling a single device to cut, treat, and sample, this technology could move surgical interventions from the operating table to less invasive outpatient procedures, fundamentally changing how precision medicine is delivered in tight anatomical spaces.
