About

Taiki Ishigaki is a robotics researcher whose work sits at the critical intersection of rigid and soft body dynamics, pushing the boundaries of how robots can safely and effectively interact with humans and their environment. His primary research areas include soft robotics simulation, humanoid motion control, and the dynamics of hybrid-link systems. Ishigaki’s major contribution is the development and application of the Piece-wise Constant Strain (PCS) model, a framework that enables fast, real-time simulation of flexible structures like beams and rods. He has applied this model to diverse challenges, from calculating the deformation of sports prostheses for athletes to enabling the dynamic simulation of entire soft robot systems. His work on "Dynamics Computation of a Hybrid Multi-link Humanoid Robot Integrating Rigid and Soft Bodies" (11 citations) is foundational, addressing the complex problem of integrating softness—a key factor in human biomechanics—into robotic systems. Ishigaki has also advanced humanoid control by developing compliance optimization methods that explicitly ensure stability during physical human-robot interaction. Through his unified framework for gradient computation, he is systematically building the mathematical tools necessary for the next generation of robots that are both strong and safe.
