Robotics and Automation

Compliant-link biped trajectory

The Robotics and Mechanisms area seeks to promote research and develop technologies that enable systems to exhibit intelligent, goal-oriented behavior, and developing innovative instruments to monitor, manipulate, and control systems. Overall, our research spans the following areas: humanoid robots, intelligent control systems, flexible manipulators, mechanism theory, microsensors and actuators, and compliant mechanism. We focus on enabling technologies that necessitate novel design solutions in terms of development of new methods of synthesis, analysis & optimization of novel robots and mechanisms.

Research Areas

 

  • Analysis, synthesis and motion planning of robots and mechanisms

  • Biped Locomotion: Design and experimentation of optimal energy efficient biped robots with compliance at foot, knee joints, etc.

  • Exoskeleton: Human motion based design and development of a three finger 10 DOF exoskeleton robot hand for rehabilitation of stroke patients.

  • Intelligent control systems: Design, development and path planning of 14 DOF Lunar rover on 3D terrain. Kinematics and redundancy resolution for performing tasks with arm on rover.

  • Micro Sensors and Actuators: Ionic Polymer Metal Composite (IPMC) based grippers and mechanisms for robotic micro assembly.

  • Smart compliant mechanisms
