Publication number: 20220410329Abstract: A method for setting more precisely a position and/or an orientation of a device head in a measuring environment by a distance measuring device which has a number of M, M?1, distance measuring sensors and which is connected to the device head. A control device is communicatively connected to the distance measuring device and an on-board sensor device. The position and/or the orientation of the device head is determined by the on-board sensor device and the position and/or the orientation of the device head determined by the on-board sensor device is set more precisely by the control device.Type: ApplicationFiled: September 23, 2020Publication date: December 29, 2022Inventors: Sascha KORL, Abel GAWEL, Hermann BLUM, Timothy SANDY, Marco HUTTER, Roland SIEGWART

Patent number: 11295162Abstract: An approach to place recognition from an image makes use of the detection of objects at a set of known places as well as at an unknown place. Images of the detected objects in an image of the unknown place are processed to yield respective numerical descriptors, and these descriptors are used to compare the unknown place to the known places to recognize the unknown place. At least some embodiments make use of a trained parameterized image processor to transform an image of an object to an object descriptor, and the training of the processor is meant to preserve distinctions between different instances of a type of object, as well as distinctions between entirely different types of objects.Type: GrantFiled: November 1, 2019Date of Patent: April 5, 2022Assignees: Massachusetts Institute of Technology, ETH ZurichInventors: Daniela Rus, Sertac Karaman, Igor Gilitschenski, Andrei Cramariuc, Cesar Cadena, Roland Siegwart

Patent number: 9082233Abstract: Techniques are disclosed for controlling robot pixels to display a visual representation of an input. The input to the system could be an image of a face, and the robot pixels deploy in a physical arrangement to display a visual representation of the face, and would change their physical arrangement over time to represent changing facial expressions. The robot pixels function as a display device for a given allocation of robot pixels. Techniques are also disclosed for distributed collision avoidance among multiple non-holonomic robots to guarantee smooth and collision-free motions. The collision avoidance technique works for multiple robots by decoupling path planning and coordination.Type: GrantFiled: March 5, 2014Date of Patent: July 14, 2015Assignees: Disney Enterprises, Inc., ETH ZURICH (EIDGENOESSISCHE TECHNISCHE HOCHSCHULE ZURICH)Inventors: Paul Beardsley, Javier Alonso Mora, Andreas Breitenmoser, Martin Rufli, Roland Siegwart, Iain Matthews, Katsu Yamane

Patent number: 6074165Abstract: A vacuum pump is provided with back-up bearings in addition to magnetic bearings for supporting its rotor with respect to the pump housing. The rotor has a hollow rotary shaft extending backwards enclosing in its inner space a forwardly protruding tubular shaft affixed to the pump housing, and another cylindrical member affixed to the rotor protrudes backward inside this fixed tubular shaft. One set of back-up bearings is provided on the outer surface of the fixed tubular shaft spaced from the inner surface of the rotor shaft and another set of back-up bearings is provided on the inner surface of the fixed tubular shaft, spaced from the protruding cylindrical member. The back-up bearings thus positioned can be made smaller for improved dynamic emergency capabilities.Type: GrantFiled: March 10, 1998Date of Patent: June 13, 2000Assignee: Varian, Inc.Inventors: Fausto Casaro, Alain Laager, Roland Siegwart

Patent number: 5682071Abstract: A magnetic bearing supports an object such as a rotor in a stable, contactless position. The bearing has electromagnets, each associated with a respective current control means (e.g., amplifier or power switch), disposed to exert magnetic forces in various directions to levitate the rotor. A constant-current source feeds a constant (total) current the electromagnets in parallel. Sensing means detect movements of the rotor from the position and inform a controller that responds by controlling the respective current to each electromagnet to maintain the rotor in position.Type: GrantFiled: May 25, 1995Date of Patent: October 28, 1997Assignee: Mecos Traxler AGInventors: Philip Buhler, Roland Siegwart, Alfons Traxler
