Embodiments of the invention provide an approach for reproducing a human action with a robot. The approach includes receiving data representing motions and contact forces of the human as the human performs the action. The approach further includes approximating, based on the motions and contact forces data, the center of mass (CoM) trajectory of the human in performing the action. Finally, the approach includes generating a planned robot action for emulating the designated action by solving an inverse kinematics problem having the approximated human CoM trajectory as a hard constraint and the motion capture data as a soft constraint.

A light distribution controller of a light-emitting device includes a first optical member formed of ZnO disposed over an LED interposing a transparent adhesive, and a second optical member which covers the first optical member. The first optical member includes a first concave portion having an opening in a regular hexagon shape whose area gradually increases. In the first concave portion, inner wall surfaces having inclined surfaces, each of whose bases is formed by one side of the hexagon of the opening shape, are formed. Outside of the first optical member, outer wall surfaces each having a trapezoidal shape are formed. The second optical member includes a second concave portion arranged so that light at an annular peak in the light distribution characteristic of the light traveled through the first optical member is totally reflected.

A method for producing a wafer bonded structure between (Al, In, Ga)N and Zn(S,Se). A highly reflective and conductive distributed Bragg reflector (DBR) for relatively short optical wave lengths can be fabricated using Zn(S,Se) and MgS/(Zn, Cd)Se materials. Using wafer bonding techniques, these high-quality DBR structures can be combined with a GaN-based optical device structure.
