Metasurfaces consisting of an array planar sub-wavelength structures have shown great potentials in controlling thermal infrared radiation, including intensity, coherence, and polarization. These capabilities together with the two-dimensional nature make metasurfaces ultracompact multifunctional platform for light manipulation. Integrating functionalities, such as amplitude, phase (spectrum dir...

The purpose of the senior design project, from the course description of objectives is "To provide students a complete design experience, including the necessity to set design goals and objectives, integrate knowledge, exercise engineering judgment, plan to meet a budget and schedule, to work as a team member, and to communicate in writing." To accomplish these objectives our group, Helping Han...

Electrically driven Stewart platforms are used in the field of machine tooling and robotics, where very accurate positions have to be reached associated with heavy loads. In this paper we present a pneumatically driven Stewart platform powered by fluidic air muscles. Due to the elasticity of the muscles and air as driving medium, the robot is predestined for applications where compliance plays ...

We report progress towards model based, dynamically stable legged locomotion with energy eecient, electrically actuated robots. We present the mechanical design of a prismatic robot leg which is optimized for electrical ac-tuation. A dynamical model of the robot and the actuator as well as the interaction with ground is derived and validated by demonstrating close correspondence between simulat...

In the last few years the market of robotics has significantly changed and the growing sector of service robotics requires new considerations in civil engineering. This paper investigates different room and furniture arrangements in the view of mobile robot navigation requirements. The described method provides robot motion and path planning cost functions for different furniture arrangements a...
