This technology implements a magnetic-based detachable docking system that allows a single transport module to individually carry multiple cargo units. By controlling the rotation direction of an external magnetic field, the assembly bar of the transport module can be selectively inserted into or withdrawn from the through-hole of the cargo microrobot.
Conventional microrobots are manufactured as independent, single-unit structures, which creates inefficiencies as each robot must be injected into the human body separately to deliver multiple different drugs or cells.
This technology features a cargo microrobot designed with a through-hole and an assembly guide, paired with a transport module equipped with an assembly bar and docking bar that can rotate and enter via an external magnetic field. This automates physical assembly and disassembly simply by changing the direction of the rotating magnetic field. Applicable to surgical robots, interventional systems, and medical automation, it improves the control of drug or cell concentration and dosage through the delivery of modular microrobots.
This invention was developed with support from the Ministry of Trade, Industry and Energy for the development of a microrobotic medical system for treating chronic total occlusion in myocardial infarction.
