Abstract: A calibration article is provided for calibrating a robot and 3D camera. The calibration article includes side surfaces that are angled inward toward a top surface. The robot and camera are calibrated by capturing positional data of the calibration article relative to the robot and the camera. The captured data is used to generate correlation data between the robot and the camera. The correlation data is used by the controller to align the robot with the camera during operational use of the robot and camera.

Abstract: In a parking assist method executed using a parking assist ECU configured to control a subject vehicle to move along a targeted parking route to a target parking position, the control amount of a yaw angle of the subject vehicle with respect to the targeted parking route is increased in accordance with the decrease in a remaining distance to the target parking position of the subject vehicle.
Abstract: A force detector provided between a robot arm and a robot hand detects forces Fx, Fy, and Fz. A robot controller performs a filtering process for the forces Fx and Fy by a first low-pass filter of a cutoff frequency Fc1, moves the robot hand so that the forces Fx and Fy become smaller, corrects a trajectory of the robot arm, performs a filtering process for the force Fz by a second low-pass filter of a cutoff frequency Fc2 having a frequency higher than the cutoff frequency Fc1, performs a threshold value determination for the force Fz, and stops the movement of the robot hand when the force Fz exceeds a threshold value during a fitting operation.
Abstract: An interactive mobile robot system and a method for creating an invisible track for a mobile robot. The system and method allow the creation of invisible tracks by guiding objects. They also allow the use of such invisible tracks for the semi-autonomous or autonomous control of toys, including model cars and model trains, or of mobile robots to move them along a real-world path. The system includes a mobile robot, receiver circuitry to receive one or more position signals, and processing circuitry. The processing circuitry is configured to determine position information associated with the mobile robot based on the one or more position signals. The processing circuitry is further configured to create an invisible track based on the position information, to determine a current position of the mobile robot, and to generate control signals based on the current position of the mobile robot and the invisible track.

Abstract: A method of controlling at least one actuator for controlling an aircraft. The method comprises data acquisition steps performed using at least two mutually distinct sensors, the sensors being suitable for taking mutually distinct measurements of at least one flight parameter of the aircraft. Calculation steps generate at least two mutually distinct control laws for controlling the actuator(s). The control laws are functions of the respective measurements. The method controls the actuator(s) sequentially with a first control law in alternation with a second control law.
Abstract: An apparatus comprises a holding unit configured to hold data related to a worker; an obtaining unit configured to obtain measurement data for recognizing the worker; a recognizing unit configured to recognize the worker based on the data related to the worker and the measurement data; a determination unit configured to determine work information about a work which the worker and a robot perform on a target object together, corresponding to the recognized worker, based on a physical feature of the recognized worker; and a controlling unit configured to control the robot based on the work information so that the worker and the robot perform a work on the target object together.
Abstract: A robotic system includes a jointed mechanism, position sensors, and a controller. The mechanism has an end-effector, and further includes actively-controlled joints and passive joints that are redundant with the actively-controlled joints. The position sensors are operable for measuring joint positions of the passive joints. The controller is in communication with the position sensors, and is programmed to execute a method to selectively control the actively-controlled joints in response to the measured joint positions using force control and/or a modeled impedance of the robotic mechanism. Possible control modes in impedance control include an Autonomous Mode in which an operator does not physically interact with the end-effector and a Cooperative Control Mode in which the operator physically interacts with the end-effector.
Abstract: A soft robotic device with one or more sensors is described. The sensor may be embedded in the soft body of the soft robotic device, attached to the soft body of the soft robotic device, or otherwise linked to the soft body of the soft robotic device.

Abstract: To improve production efficiency while maintaining stability of an operation of a robot arm. A dust position determination unit determines whether there is a read error based on a read result of a detection head of an encoder. In a case where the dust position determination unit determines that there is a read error, an error determination unit judges in which region, among an allowable region and a non-allowable region, the read error occurs. In a case where the read error is judged to occur in the allowable region, the error determination unit continues an operation of the robot arm.
Abstract: A control system includes an airborne flight control system and a smart terminal; the airborne flight control system is configured to acquire a first position information, and send the first position information to the smart terminal; the smart terminal is configured to acquire a second position information, and obtain a yaw angle and at least one of a horizontal flight speed and a vertical flight speed according to the second position information and the first position information sent by the airborne flight control system, and send the yaw angle and at least one of the horizontal flight speed and the vertical flight speed to the airborne flight control system, wherein the first position information is the position information of an aircraft where the airborne flight control system is located, and the second position information is the position information of the smart terminal.

Abstract: Vehicles are disclosed that are configured to carry loads in a stabilized manner, such that the load is maintained in a substantially constant position or orientation relative to a predetermined reference point or frame even as the vehicle moves. A stabilization controller in such a vehicle receives information about movement of the vehicle relative to the reference point or plane from one or more sensors on the vehicle, and uses the information to control one or more movable objects by which the load is secured to the vehicle so as to maintain a relatively constant relationship between the load and the reference point or plane.
