    • Abstract:  Abstract This paper presents a modular demonstration tool for robot programming by human demonstration and an approach for the calibration of the tool's sensors. The tool is equipped with a wrench sensor, twelve LED markers for fast and accurate six dimensional position tracking with the Krypton K600 camera system, a compact camera and a laser distance sensor. A gripper mechanism is mounted on the tool for grasping and manipulating objects. The design of the tool specifically focused on the demonstration of compliant motion task, with applications in manipulation and assembly tasks. The calibration approach first uses an extended Kalman Filter to convert the measured positions of three to twelve visible LED's into the pose of the tool frame relative to the Krypton camera frame. Then, using a non minimal state Kalman filter, the force sensor calibration parameters are calculated, and the orientation of the Krypton camera frame relative to the world frame is defined. This calibration approach is verified in a real world experiment.

          NEW YORK (Reuters) - Less than two weeks ago anyone looking to buy a ticket to watch the New York Knicks play the Dallas Mavericks this weekend could expect to pay around $270. Today, the same ticket would cost about twice that. Call it Linflation. Jeremy Lin's surprising basketball heroics have made the 23-year-old point guard a sports sensation and media darling nearly overnight, and there are ...

Glencore made its long-awaited bid last week, unveiling a potentially record deal both sides believe will create a mining and trading powerhouse, and offering 2.8 of its shares for every 1 ...
