Study of human motor control and task performance with circular constraints
This thesis aims to investigate human motor control strategies. Curved constraints offer a unique opportunity to exploit forces of contact. A circular crank experiment using the MIT MANUS robot was designed in order to test how well subjects can follow a set of simple instructions to rotate the …

Time domain characteristics of human force control in rejection of transient disturbances during movement
Many tasks that humans successfully complete are more naturally represented in terms of their force requirements than their state (position or velocity) requirements. Yet the literature on force and timing is relatively underrepresented. This work was an attempt to clarify whether feedforward …

Optimal control strategies for saccadic eye movements in humans
Human motor control systems are complicated by issues of nonlinearity, redundancy, and multiple degrees of freedom. A great variety of mathematical and engineering approaches have been applied to the problem of modeling human movement systems: open and closed loop control, dynamic optimization, …

Quantifying and modelling adaptive astronaut movement : motion strategies for long-duration spaceflight missions
… experience has shown that astronauts adapt their motor control strategies to microgravity movements after approximately four weeks of microgravity exposure. A similar (but typically shorter) re-adaptation period is required upon return to Earth or partial gravity environment such as the Moon or …

Characterization and control of a robot for wrist rehabilitation
Human motor control pathologies, such as those caused by stroke, can be treated through physical rehabilitation. The use of robots in therapy environments seems appropriate considering the possibilities they offer for quantification of performance as well as "quality control" between therapy …

Robotic compensation of cerebellar ataxia
… to play a role in dynamic compensation in the human motor control system. When it is damaged, subjects make clumsy movements with reduced acceleration, increased overshoot, and swerving in multi-joint movements. These errors, which are referred to clinically as ataxia, are consistent with …

A Dynamic Primitives Hypothesis: a Descriptive Model of Human Physical Interaction
… development of prosthetics, exoskeletons, and human-robot interaction. Motor neuroscience has reported systematic patterns of motion during free reaching and force during static posture. However, similar results do not extend to physical interaction. A descriptive model is required. The paradox …

All Models are Wrong, Simple Models Provide Insight: A Study of Human Manipulation
Humans possess a unique ability to manipulate tools, facilitated by the dexterity of our hands. Unfortunately, millions lose this capability annually due to conditions like limb amputation or Cerebral Vascular Accident. Robotic rehabilitation technologies, including prosthetics and exoskeletons, …

An agonist-antagonist myoneural interface for proprioception from a neurally-controlled prosthesis
Humans have the ability to precisely sense the position, speed, and torque of their body parts. This sense is known as proprioception, and is essential to human motor control. In the many attempts to create human-mechatronic interactions, there is still no robust, repeatable methodology to reflect …

Humanoid robot dynamic synchronization via whole-body teleoperation with bilateral feedback
… physical actions with comparable performance to humans. Yet, the potential applications for robots with such unique capabilities range from disaster response all the way to elderly care and further. Hence, an intuitive short-term answer for this issue lies on harnessing human motor control …

Shoulder pain in manual wheelchair users: towards a multi-disciplinary solution for a multi-faceted problem
… theories and analyses from fields related to human movement science such as human motor control theory, non-linear dynamics and human factors (occupational ergonomics) are adopted to identify potential biomarkers that relate to shoulder pain in manual wheelchair users. This dissertation …

Robust adaptive control modeling of human arm movements subject to altered gravity and mechanical loads
… in ways that can be described by an adaptive control method. The investigation presented in this thesis includes two different sets of experiments. A series of dart throwing experiments took place onboard the space station Mir. Experiments also took place at the Biomechanics lab at MIT, where …

Effect of control interface implementation on operation of a multi degree of freedom telerobotic arm
In exploration, scenarios can include a human working along-side - or attached to - a robot. For example, concepts of Mars human-robot exploration teams, or extravehicular activity (EVA) on the International Space Station (ISS) with an astronaut fixed to the end of a large robot arm for stability. …
