Design and analysis of the three degrees of freedom parallel kinematic machine
The thesis is about design and analysis of a PKM with 3 DOF. The new PKM is designed as a machine tool in various applications in manufacturing. The PKM is optimized based on the developed stiffness model. Kinematics and dynamics of the new PKM is also modeled and simulated.

Cutting Mechanisms in Micro-Endmilling and Their Influence on Surface Generation
… process conditions, spindle runout, process kinematics and dynamics on the machined surface roughness. One of the most important findings is that a feedrate of 1-1.5 times of the minimum chip thickness is a good starting point for process planning to achieve small surface roughness.

Biped robot with a vestibular system
The kinematics and dynamics of two legged or biped walking is considered. The resulting governing equations include actuator torques for a robot and muscle generated torques for a human. These torques are those necessary at each joint of a leg, including the foot, for a successful stride. The …

Autonomous Robotic Automation Systemwith Vision Feedback
In this thesis, a full design, development and application of an autonomous robotic automation system using vision feedback is performed. To realize this system, a cylindrical manipulator configuration is implemented, using a personal computer (PC) based PID controller from National Instruments. …

Navier-Stokes simulations of steep breaking water waves with a coupled air-water interface
… facilitates the transfer of mass, momentum, heat and energy across the air-sea interface. In the context of the near field flow about a surface ship, the breaking bow wave is a key element to the bubbly signature and an appreciable portion of the wave drag of the ship. Yet, despite its direct …

Stability optimization of open-loop controlled walking robots
… fundamentally new open-loop stable one-legged and two-legged walking robots. It thus demonstrates that the concept of open-loop control is applicable to a much wider range of systems than was conceived before. An open-loop stable control strategy does not use any feedback nor does it take any …
