    Abstract: A robot apparatus includes a manipulator including a hand and an arm, a teaching apparatus that teaches operation of the manipulator, and a control apparatus that controls the manipulator that operates in a regular operation status or an erroneous manipulation avoiding status based on a control signal from the teaching apparatus. After determining whether a status of the manipulator is the regular operation status or the erroneous manipulation avoiding status, the control apparatus transmits a control signal for performing operation at a set regular speed to the manipulator in a case of the regular operation status, and the control apparatus transmits a control signal for performing operation at a speed lower than or equal to a safety speed that is set based on the regular speed to the manipulator in a case of the erroneous manipulation avoiding status.

  • Publication number: 20150107395
    Abstract: Systems and methods relating to a clutch system for use in controllably transmitting torque from an input shaft to an output shaft. The clutch system has a torque transmission fluid that has a viscosity that changes based on the strength of an electromagnetic field passing through the fluid. A number of sensors are placed at different radial locations on the torque transmission disks to detect the strength of the electromagnetic field. Based on the strength of the electromagnetic field, the amount of torque being transmitted from the input shaft to the output shaft can be adjusted. Also disclosed is a distributed actuation architecture that uses this clutch system. The distributed actuation architecture allows for the use of a single drive motor in conjunction with multiple instances of the clutch system to actuate a mechanical linkage, such as a robotic arm.

    Abstract: In sensor-less collision detection of a robot, a conventional method for displaying abnormality of the robot makes an abnormality display of “collision detected” when a collision is erroneously detected, and does not clarify the situations under which the collision has been erroneously detected. In a method for displaying abnormality of a robot, when a collision of the robot is detected and the collision detection is displayed, at least one abnormality display is selected from a plurality of abnormality detection items different from collision detection. This can offer information useful for the user to understand the situations at occurrence of the erroneous collision detection.

The overload lever has a first end that receives an applied force and an opposing second end. A zero length spring mechanism is coupled to a second part of the driven load spaced apart from the first part and to the second end of the overload lever. The zero length spring mechanism urges the second end of the overload lever toward the second part of the driven load with a force that is substantially proportional to the distance between the second end of the overload lever and the second part of the driven load. A stop mechanism is coupled to the zero length spring mechanism to maintain a minimum distance between the second end of the overload lever and the second part of the driven load.

  • Patent number: 8942850
    Abstract: A method for handling of a first robotized mobile machine moving in a congested working environment under the control of a second robotized mobile machine, providing the operator, in real time, with a relevant view of the working scene, even if an object intrudes into the field of view of the camera and thereby obscures the operator's view. This method is based on use of properties of a physics engine of the constraint resolution type. For each object in the scene, the physics engine has a physical representation of said object in the form of a mesh. The engine calculates a wrench on the basis of the respective positions and velocities of two objects. In case of a collision between the manipulator and a fixed object in the scene, the engine determines the wrench to be applied to the manipulator in order to make it avoid the object.

    Abstract: A robotic tool changer removably attaches a robotic tool to a robotic arm. The changer includes a tool module connected to the robotic tool, and a master module connected to the robotic arm. To attach and detach the robotic tool, the changer couples and uncouples the tool module and the master module. A master electrical signal module (ESM) affixes to the master module and a tool ESM affixes to the tool module. In accordance with design requirements, the changer applies the same power supply to both the master ESM and the tool ESM. The changer, however, selectively suppresses application of the power supply to the tool ESM, while maintaining application of the power supply to the master ESM, during the coupling or uncoupling of the master module and the tool module. In doing so, the changer enables such coupling and uncoupling, while also preventing the formation of transient electric arcs.
