About

Rajendran Saaj is a pioneering researcher in soft robotics and safe human-robot interaction, with a focus on medical applications. His key research areas include continuum manipulators, pneumatic actuation, and teleoperated surgical systems. Saaj's most notable contribution is the first demonstration of a pneumatic soft continuum robot integrated in series with a rigid robot arm for safe teleoperated diathermic tissue-cutting. This innovative system autonomously maintains a safe tool contact force via the rigid arm while allowing manual path following through the soft arm, significantly reducing the risk of tissue damage during electrical diathermy. His seminal 2018 paper on this work has garnered 6 citations, establishing a foundation for safer surgical robotics. Saaj's approach uniquely combines the precision of rigid robotics with the compliance of soft materials, addressing critical safety challenges in minimally invasive surgery. His work has implications for developing next-generation surgical assistants that can adapt to delicate tissue environments, making him a key figure in advancing soft continuum manipulators for medical use.
