An exploration of sensorless manipulation
IEEE Journal on Robotics and Automation, 1986The use of motion strategies to eliminate uncertainty, without the use of sensors, is considered. The approach is demonstrated within the context of a simple method to orient planar objects. A randomly oriented object is dropped into a tray. When the tray is tilted, the object can slide into walls, along walls, and into corners, sometimes with the ...

Recent developments in sensorless and quasi‐sensorless drive
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2002There are two main types of speed/position sensorless closed‐loop variable‐speed electrical drives: sensorless and quasi‐sensorless drives. In sensorless drives, the classical speed and position sensors (transducers) are absent and are replaced by mathematical‐model‐based and/or artificial‐intelligence‐based estimators.

AIAA Guidance, Navigation, and Control Conference and Exhibit, 2001
The paper introduces a control technique for autonomous formation flight that does not require inter-aircraft distance measures to maintain formation stiffness. In a two aircraft formation, the leader induces a wake on its wingman and a neural network structure is synthesized to estimate the relative position.

IEEE Transactions on Industrial Electronics, 2011
This paper investigates the effectiveness of sensorless operation in carrier-signal-injection-based sensorless-control methods for permanent-magnet brushless ac motors. The sensorless safety operation area (SSOA) is introduced with due account for the quantization error in the analog to digital conversion.

Sensorless control for synchronous motors
2010 International Conference on Autonomous and Intelligent Systems, AIS 2010, 2010Permanent magnet synchronous motors are used in many industrial applications because they have several inherent advantages. However, information about the rotor position is necessary even to be able to control drive speed. Conventional speed and position detection uses encoder and resolver.

Sensorless friction and gravity compensation
2014 IEEE-RAS International Conference on Humanoid Robots, 2014In this video we present a new controller for robots, called Zero-Friction Zero-Gravity control. The controllers combine terms for compensating the forces exerted by gravity, and the forces of friction of motors and reductions. The consequence of applying this control to a robot (a humanoid robot arm in this case) result in a free movement, as if the ...

Sensorless In-Hand Caging Manipulation
2017In this paper, we study a method to manipulate objects in position-controlled robot hands: in-hand caging manipulation. In this method, an object is caged by a hand throughout manipulation and located around a goal as a result of the deformation of the cage without sensing the object configuration.
