About

Norazhar Abu Bakar is a researcher focused on humanoid robotics and assistive motion control, with a particular emphasis on replicating human sit-to-stand (STS) transitions in robotic systems. His work addresses a fundamental challenge in rehabilitation robotics and human-robot interaction: enabling robots to perform the complex, multi-phase motion of rising from a seated position. In his key studies, including "Horizontal Distance Identification Algorithm for Sit to Stand Joint Angle Determination for Various Chair Height Using NAO Robot" and "STS Motion Control Using Humanoid Robot," Abu Bakar developed novel methods for phase and trajectory planning to solve the critical "lift-off from chair" problem. His research systematically analyzes how varying chair heights affect joint angles and motion dynamics, contributing foundational algorithms for more natural and adaptive robotic movement. While his citation counts remain modest, his work represents important early steps in applying humanoid robots like NAO to study and replicate human STS motion—a capability with direct applications in assistive devices, physical therapy, and prosthetic control. Abu Bakar’s contributions help bridge the gap between human biomechanics and robotic implementation, offering valuable insights for researchers developing robots that can safely and effectively assist elderly or mobility-impaired individuals.
