Establishment of a method for correcting the image coordinates of a target captured by a robotic fish with rolling motion

Nihon Kikai Gakkai ronbunshu, 2021
A robotic fish is ideal for an ecological survey of underwater life, because underwater animals cannot easily notice the robot. However, when a robotic fish swings its body to swim, it makes a rolling motion due to movements of the center of gravity and ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching
