Publication number: 20140221894Abstract: Intentions of a user are read from movements of the joints of the user without the use of a myoelectric sensor, and a force to support motions of the user is generated. Even if there is friction that is difficult to model in a gear portion of a joint actuator, the friction is compensated for, and joint units are controlled to follow an idealized mathematical model. In this manner, the force to support motions is generated, without giving any uncomfortable feeling to the joints of the user wearing the device. When motions of the user are supported, a mathematically-determined torque is applied to the joint units, so that a natural supporting force is constantly provided to the user in various circumstances.Type: ApplicationFiled: July 3, 2012Publication date: August 7, 2014Applicant: SONY CORPORATIONInventor: Kenichiro Nagasaka

Patent number: 8798794Abstract: An object is highly precisely moved by an industrial robot to an end position by the following steps, which are repeated until the end position is reached within a specified tolerance: Recording a three-dimensional image by means of a 3-D image recording device. Determining the present position of the object in the spatial coordinate system from the position of the 3-D image recording device the angular orientation of the 3-D image recording device detected by an angle measuring unit, the three-dimensional image, and the knowledge of features on the object. Calculating the position difference between the present position of the object and the end position. Calculating a new target position of the industrial robot while taking into consideration the compensation value from the present position of the industrial robot and a value linked to the position difference. Moving the industrial robot to the new target position.Type: GrantFiled: May 26, 2010Date of Patent: August 5, 2014Assignee: Leica Geosystems AGInventors: Bernd Walser, Bernhard Metzler, Beat Aebischer, Knut Siercks, Bo Pettersson

Publication number: 20140214207Abstract: A robot includes a first horizontal arm coupled to a base, a second horizontal arm coupled to the base via the first horizontal arm, first and second motors adapted to rotate the respective arms, and first and second encoders adapted to calculate rotational angles and rotational velocities of the respective motors. A first motor control section subtracts first and second angular velocities based on the first and second encoders from a sensor angular velocity detected by an angular sensor, and controls the first motor so that a velocity measurement value obtained by adding a vibration velocity based on a vibration angular velocity as the subtraction result and a first rotational velocity becomes equal to a velocity command value.Type: ApplicationFiled: March 27, 2014Publication date: July 31, 2014Applicant: SEIKO EPSON CORPORATIONInventors: Katsuji IGARASHI, Masaki MOTOYOSHI

Publication number: 20140195050Abstract: A cleaning robot is disclosed. A first sensing unit generates a sensing signal to a transmittal line according to an external wireless signal. When the external wireless signal is sensed by the first sensing unit, a state of the transmittal line does not match with a pre-determined state. When the external wireless signal is not sensed by the first sensing unit, the state of the transmittal line matches with the pre-determined state. A control unit generates a movement signal when the state of the transmittal line matches with the pre-determined state. A plurality of wheels rotate according to the movement signal. A second sensing unit generates a second sensing signal according to the external environment of the cleaning robot. When the state of the transmittal line does not match with the pre-determined state, the control unit adjusts the movement signal according to the second sensing signal.Type: ApplicationFiled: March 12, 2013Publication date: July 10, 2014Applicant: MSI COMPUTER (SHENZHEN) CO., LTD.Inventors: Yi-Feng LIN, Hung-Chou CHEN, Shih-Che HUNG
