Abstract: A method and system for automatically setting a payload weight value for a collaborative robot, where one or more objects are picked up by a robot gripper, the weight of the objects is automatically determined by a force sensor and the weight is used for the payload, and the payload value is automatically adjusted when any of the objects is dropped off. Only one weight measurement is needed when all objects are known to be of the same weight, and objects of different weights can be handled with a weight measurement for each object. The system handles payload adjustment automatically without the need for manual adjustment or custom programming. The robot uses the payload weight value when detecting any externally applied force indicating contact with an operator or other object, and also for ensuring that payload accelerations do not exceed gripping force capacity or robot joint load limits.

Abstract: A system and method for calculating a robot reference frame. The method includes placing a calibration object, such as a box, at a first location, positioning the robot relative to a center of the calibration object when the calibration object is at the first location, grasping the calibration object by the robot when the calibration object is at the first location, and recording a first position value identifying the first location. The method further includes moving the calibration object from the first location to a second location using the robot, recording a second position value identifying the second location, and calculating a third position value using the first and second position values. The method also includes calculating an intermediate frame using the first, second and third position values, and calculating the reference frame using the intermediate frame and dimensions of the calibration object.

Abstract: Sealant injection systems for injecting sealant into a cavity, the sealant injection systems including a sealant dispensing tip having a proximal end portion, a body portion, and a distal end portion that define a continuous channel to an aperture in the distal end portion for dispensing sealant material into a cavity, where the aperture is surrounded by a compressible material. The distal end portion may have a linear ridge defined on an end face, the aperture being asymmetrically provided relative to the ridge.
