Ritwik Chattaraj

About

Ritwik Chattaraj is a robotics and biomedical engineering researcher whose work sits at the compelling intersection of assistive technologies, intelligent control systems, and advanced robotic manipulation. His research has made significant strides in developing solutions for individuals with physical disabilities, most notably through multimodal wheelchair control systems that integrate EMG signals with joystick interfaces for holonomic omnidirectional movement, and lower limb active knee exoskeletons that reconstruct lost gait patterns through myoelectric control — work that has collectively earned over 35 citations. Chattaraj has also contributed meaningfully to the field of robotic gripping, exploring dexterous hand grasp mapping, compliant micro-grippers, gesture-based control via IPMC actuators, and tele-operation exploiting human hand synergies. His investigations into ionic polymer-metal composite (IPMC) actuators, including shape estimation and optimized hyper-redundant kinematic modeling, demonstrate a sophisticated understanding of smart material systems. Complementing these efforts, his navigation research — encompassing depth-map-based door negotiation and augmented reality-guided potential field control — underscores a holistic approach to autonomous mobile robotics. With foundational contributions across assistive robotics, bio-signal processing, and smart actuator design, Chattaraj represents a versatile and socially motivated engineering researcher.
