Laboratory activities

The activities in this lab aim to create dynamic simulations of movement to understand cause-effect relationships between neuromuscular control mechanisms and the resulting movement both in human and animal models.Activities in this lab also investigate the possibility of simulating the dynamics of movement in human subjects wearing assistive devices such as orthotic and prosthetic devices. This is directed at optimizing orthotic and prosthetic designs to enhance their performance and interaction with the user.Finally, robotic bipedal systems are simulated as a means to design and test advanced motor control strategies.
