  • Patent number: 8880221
    Abstract: A humanoid robot fall controller controls motion of a robot to minimize damage when it determines that a fall is unavoidable. The robot controller detects a state of the robot during the fall and determines a desired rotational velocity that will allow the robot to re-orient itself during the fall to land on a predetermined target body segment (e.g., a backpack). The predetermined target body segment can be specially designed to absorb the impact of the fall and protect important components of the robot.

  • Patent number: 8830091
    Abstract: The invention is related to methods and apparatus that use a visual sensor and dead reckoning sensors to process Simultaneous Localization and Mapping (SLAM). These techniques can be used in robot navigation. Advantageously, such visual techniques can be used to autonomously generate and update a map. Unlike with laser rangefinders, the visual techniques are economically practical in a wide range of applications and can be used in relatively dynamic environments, such as environments in which people move. One embodiment further advantageously uses multiple particles to maintain multiple hypotheses with respect to localization and mapping. Further advantageously, one embodiment maintains the particles in a relatively computationally-efficient manner, thereby permitting the SLAM processes to be performed in software using relatively inexpensive microprocessor-based computer systems.

    Abstract: Systems, methods, and computer programs are presented for an end effector with a dual optical sensor. One end effector includes an arm, a mapping sensor, and a load sensor. The arm has one end connected to a pivoting joint, and a light signal is routed around the arm through a single light path. The mapping sensor is used for identifying the presence of the wafer when the wafer is not loaded on the end effector. The load sensor is used for identifying presence of the wafer on the end effector when the wafer is loaded on the end effector. The load sensor is defined by a second segment in the single light path such that the wafer intersects the second segment and interferes with the single light path when the wafer is loaded. A control module determines if an interruption in the single light path corresponds to an interruption of the single light path in the mapping sensor or the load sensor. As a result, one single light sensor is used to sense for two different conditions in the end effector.

  • Patent number: 8659256
    Abstract: A robot confinement system includes a portable housing and a mobile robot. The portable housing includes an emitter operable to emit a first signal when a presence of the robot is detected in a field of detection. The robot includes a controller operable to control a movement path of the robot on a surface and a cleaner operable to clean the surface as the robot moves on the surface. The robot further includes a detector operable to detect the first signal emitted by the portable housing. The controller is operable to change the movement path of the robot in response to detection of the first signal. One of the portable housing and the robot is operable to detect a second signal generated by the other of the portable housing and the robot to detect the presence of the robot in the field of detection.

  • Patent number: 8649904
    Abstract: A robotic device having an arm including an actuator and inertial sensor, a first calculator adapted to calculate an angular velocity and an angular acceleration of the actuator based on a rotational angle data from an angle sensor, a second calculator adapted to calculate one of an angular velocity and an angular acceleration of the arm based on an output detected by the inertial sensor, and a comparator adapted to compare one of the angular velocity and the angular acceleration calculated by the first calculator and one of the angular velocity and the angular acceleration calculated by the second calculator with each other, and it is determined that the inertial sensor is at fault if an absolute value of the difference between the actuator and the arm in one of the angular velocity and the angular acceleration in the comparison section is larger than a threshold value.

  • Patent number: 8630729
    Abstract: A method for verifying completion of a task. Location coordinates of at least one location sensor within a work cell are obtained. At least one sensor is affixed to a tool used to operate on a feature of a structure to be assembled, fabricated or inspected. A virtual object locus is generated based on the location coordinates of the at least one location sensor. The virtual object locus corresponds to a computerized schematic of the structure to be assembled and represents of all possible locations of an object end of the tool within the work cell. One of a plurality of candidate features is identified as the most likely to be the feature operated on by the tool. The identification is based on a probability calculation for each of the candidate features that each respective candidate feature is the feature operated on by the tool.

  • Patent number: 8630763
    Abstract: A single track in-line legged vehicle is controlled to coordinate movement along a desired single-track trajectory by causing each in-line leg to selectively perform a stance-to-flight phase, a flight phase, a flight-to-stance phase, and a stance phase. During the stance-to-flight phase, reaction forces and torques between a foot and the ground are unloaded to lift the foot off the ground. During the flight phase, a foot moves in the same general direction and at a generally faster rate as a major direction of motion of the vehicle body. During the flight-to-stance phase, foot positioning is controlled to place a foot on the ground according to the desired single-track trajectory. During the stance phase, foot-to-ground interaction develops reaction forces and torques that are transferred from the foot through the corresponding in-line leg to propel, torque, and stabilize the body in the x, y, z, pitch, roll, and yaw axes.

  • Patent number: 8620489
    Abstract: The subject disclosure is directed towards a robot device including a computational intelligence system that can be coupled to/decoupled from different interchangeable mobility mechanisms at different times. The robot may operate with its intelligence portion detached from the mobility portion, whereby the intelligence portion may be easily to interact therewith out lifting the (typically dirty) mobility mechanism. The robot may operate according to a coupled state, a decoupled state, or in a transition state when being moved for purposes of coupling or decoupling.

  • Patent number: 8598829
    Abstract: A piezoelectric debris sensor and associated signal processor responsive to debris strikes enable an autonomous or non-autonomous cleaning device to detect the presence of debris and in response, to select a behavioral mode, operational condition or pattern of movement, such as spot coverage or the like. Multiple sensor channels (e.g., left and right) can be used to enable the detection or generation of differential left/right debris signals and thereby enable an autonomous device to steer in the direction of debris.
