About

Tadayuki Tsujita is a robotics researcher whose work focuses on enabling humanoid robots to exert large forces through dynamic, whole-body motions. His primary research areas include impact motion generation, humanoid balance control, and high-speed visual perception. Tsujita’s most significant contributions center on the concept of “impact motions”—impulsive, coordinated movements that allow robots to perform forceful tasks like nailing, while maintaining stability. His 2008 paper, “Analysis of nailing task motion for a humanoid robot” (8 citations), and its companion, “Optimization of impact motions for humanoid robots” (7 citations), pioneered the use of Sequential Quadratic Programming (SQP) to optimize these motions, balancing force output with multibody dynamics and postural stability. This work addresses a fundamental challenge in humanoid robotics: generating large environmental forces without falling. Beyond impact motions, Tsujita contributed to robotic vision by co-developing a high-speed binocular camera head (2006, 5 citations), designed to replicate human-like saccadic eye movements using neuromorphic vision chips. His research bridges biomechanics, control theory, and hardware design, offering practical pathways for humanoids to perform physically demanding tasks. With a focused publication record, Tsujita’s work remains a valuable reference for researchers exploring dynamic, force-intensive manipulation in humanoid platforms.
