20100059298 | WALL CRAWLING ROBOTS - Described herein is electroadhesion technology that permits controllable adherence between two objects. Electroadhesion uses electrostatic forces of attraction produced by an electrostatic adhesion voltage, which is applied using electrodes in an electroadhesive device. The electrostatic adhesion voltage produces an electric field and electrostatic adherence forces. When the electroadhesive device and electrodes are positioned near a surface of an object such as a vertical wall, the electrostatic adherence forces hold the electroadhesive device in position relative to the surface and object. This can be used to increase traction or maintain the position of the electroadhesive device relative to a surface. Electric control of the electrostatic adhesion voltage permits the adhesion to be controllably and readily turned on and off. | 03-11-2010 |
20120111649 | Suspension for an endless track climbing machine - An endless-track type climbing vehicle containing a multi-link suspension apparatus to uniformly distribute the forces on the on the adhering members while traversing irregular climbing surfaces. The multi-links suspension apparatus is able to conform to large range of surface irregularities while providing push and pulling forces on the adhering members to uniformly distribute the climbing loads on the adhering members. The result is a climbing machine that can accommodate large surface irregularities while maximizing the climbing payload with a minimum number and size of adhering members. | 05-10-2012 |
20140124276 | Dual Rotor Electric Drive - A series electric drive includes a cylindrical first rotor with a number of permanent magnets therein and an input linked to the cylindrical first rotor. The series electric drive further includes a cylindrical second rotor stacked radially within the cylindrical first rotor, the cylindrical second rotor being a wound rotor, and an output being linked to the cylindrical second rotor. A cylindrical stator is stacked axially relative to the first rotor, and a portion of the second rotor is stacked radially within the cylindrical stator, the cylindrical stator being a wound stator. | 05-08-2014 |
