            <link>http://www.freepatentsonline.com/8112178.html</link>
            <description><![CDATA[A robotic platform for autonomous automotive vehicle development. The platform includes a frame having a plurality of wheels rotatably mounted to the frame. A motor mechanism is associated with at least one of the wheels and the motor mechanism is responsive to drive signals to rotatably drive its associated wheel. At least one sensor is mounted to the vehicle which provides an output signal representative of a parameter relevant to the position of the robotic platform. A programmable control circuit is programmed to generate drive signals in response to the sensor output(s) to simulate the operation of an automotive vehicle for vehicle development.]]></description>

            <description><![CDATA[A system of self-organizing mobile robotic agents (MRAs) in a multi-robotic system (MRS) is disclosed. The MRAs use simulations to organize the behaviors of groups of robots in the MRS. The MRAs use software agents to model the MRS and the environment. By developing simulations of environmental change, the system provides methods for the MRS to interact with its environment to produce collective epigenetic behaviors.]]></description>

            <description><![CDATA[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.]]></description>

            <link>http://www.freepatentsonline.com/8109549.html</link>
            <description><![CDATA[Various endeffector designs are disclosed for handling semiconductor wafers. For instance, an endeffector for handling wafers at a relatively low temperature is disclosed along with an endeffector for handling wafers at a relatively high temperature. Both endeffectors include uniquely designed support members that are configured to only contact a wafer at the wafer's edge. The endeffectors may also include a wafer detection system. The endeffector for handling wafers at relatively low temperatures may also include a pushing device that is used not only to position a wafer but to hold a wafer on the endeffector during acceleration or deceleration of the endeffector caused by a robot arm attached to the endeffector. As designed, the endeffectors may have a very slim profile making the endeffectors easily maneuverable.]]></description>

            <link>http://www.freepatentsonline.com/8109173.html</link>
            <description><![CDATA[A parallel robot including a movable-section drive mechanism having a parallel mechanism configuration and operating to allow a movable section to perform a three-axis translational motion with respect to a base section, and a wrist-section drive mechanism operating to allow a wrist section to perform a three-axis orientation-changing motion with respect to the movable section. The wrist section includes a first rotary member supported on the movable section and rotatable about a fourth rotation axis different from axes of the three-axis translational motion of the movable section, a second rotary member connected to the first rotary member and rotatable about a fifth rotation axis orthogonal to the fourth rotation axis, and a third rotary member connected to the second rotary member and rotatable about a sixth rotation axis orthogonal to the fifth rotation axis. The third rotary member is provided with an attachment surface to which a tool is attached. The attachment surface is inclined with respect to the sixth rotation axis at a predetermined angle.]]></description>

            <description><![CDATA[An umbilical member motion limiting device is provided on a robot which has a forearm, a wrist portion, an operating tool attached to the end of the wrist portion, and the umbilical member connected to the operating tool through the forearm, for limiting the motion of the umbilical member corresponding to the motion of the robot. The motion limiting device comprises a swing portion attached to the wrist portion so as to swing around a swing axis and a limiting portion arranged on the swing portion for limiting the motion of the umbilical member. Thus, the motion limiting device can minimize interference due to surplus length of the umbilical member and avoid contact of the umbilical member with external equipment.]]></description>
