The Needle Robot Sent Force Through Fluid
A magnetic-resonance-safe master-slave manipulator combines manual, digital and collaborative control for bedside intervention.
Summary
A magnetic-resonance-safe master-slave manipulator combines manual, digital and collaborative control for bedside intervention.
The 2+1-degree-of-freedom system uses elastomeric fluid actuators for remote angulation and low-friction graphite piston cylinders for needle insertion, with sub-newton force transparency and sub-millimeter motion transmission reported over bedside piping lengths. The team demonstrated assisted tissue penetration, virtual fixtures and motion compensation, then reported functional viability in a preliminary in-vivo pig experiment inside an MRI scanner. This is early device research, not evidence of safety or effectiveness in human procedures.
