Redundant Robot Kinematic Control with Hard Constraints

First-author real-time generalized SNS framework for constrained kinematic control in redundant robots.

Outcome

I developed a computationally efficient generalized SNS-based kinematic control framework for redundant robots with online handling of variable hard constraints.

Problem

Industrial and service manipulators must remain feasible in real time while enforcing strict joint and Cartesian constraints. This project addressed robust online feasibility with both simulation and hardware validation.

System

  • Formulation: generalized inequality-constrained redundancy resolution
  • Solver: generalized SNS-based online task scaling for hard constraints
  • Implementation: real-time-feasible algorithmic pipeline
  • Validation: simulation and hardware experiments on redundant manipulators
