Bio

Dr. Mario W. Gomes completed a B.S. degree in Mechanical Engineering at Cornell University and a M.S. in Mechanical Engineering at the Georgia Institute of Technology. After working for a few years as a mechanical engineer, he returned to Cornell University and completed his Ph.D. in Theoretical and Applied Mechanics. Dr. Gomes previously worked in industry as a Project Engineer and served as a Lecturer at Arizona State University.

Dr. Gomes’ research focuses on the application of rigid-body dynamics to energy systems with the goal of developing new renewable energy sources and exploiting natural dynamic behavior to conserve energy in existing systems. Dr. Gomes has studied Passive Dynamic Walking systems as an undergraduate by creating and using simulations of a 2D-knee-jointed walker. Passive Dynamic walkers are an uncontrolled assembly of sticks and hinges which, when designed correctly, and given the appropriate initial conditions can fall in to a stable human-like walking cycle down a ramp. His master's work was in the field of Passive Haptic displays, where he developed control approaches for force-feedback systems which were only able to dissipate the user's energy. These systems are inherently safe for the user since the power flow is only in one direction, from the user into the system, and not vice-versa. His Ph.D. work examined the limits of performance for locomoting apes and robots, specifically brachiation (ape-swinging) robots, and passive dynamic walking robots. By creating physics based computer models, he showed that it was possible for very simple models to walk across level ground (or brachiate under flat ceilings) with zero energy required to sustain the motion.

Dr. Gomes' current research interests are in fields of

dynamics and design of tethered airfoils (kites) for energy production
locomotion mechanics
mechanical energy storage systems
engineering education (project-based learning)

Dynamics

3 Credits

A basic course in the kinematics and kinetics of particles and rigid bodies. Newton's Laws and the theorems of work-energy and impulse momentum are applied to a variety of particle problems. Systems of particles are employed to transition to the analysis of rigid body problems. Absolute and relative motion are used to investigate the kinematics and kinetics of systems of rigid bodies. Newton's Laws are applied to a variety of two-dimensional rigid body problems.
