  • Publication number: 20250345929
    Abstract: The present disclosure provides a vision based control of a reconfigurable soft robotic gripper. Conventional methods lack an intelligent control method which automatically adapts the configuration of the gripper based on the target object. The present disclosure includes a robotic gripper with a rigid palm and three soft fingers attached to the palm. Each finger is separately actuated using three separate motors. Out of the three fingers, one is fixed, and other two can move relative to the base, the motion of the movable fingers is actuated by motor(s). Each finger has multiple sensors to detect the magnitude of bending. A camera is attached to the base of the gripper, facing the object to be grasped. The camera image and the sensors measurements are given to a control unit and the control unit in turn gives the control signal to the actuator motors to suit the object to be grasped.

  • Patent number: 12462411
    Abstract: This disclosure relates generally to method and system for predicting distance of gazed objects using IR camera. Eye tracking technology is widely used to study human behavior and patterns in eye movements. Existing gaze trackers focus on predicting gaze point and hardly analyzes distance of the gazed object from the gazer or directly classify region of focus. The method of the present disclosure predicts gazed objects distance using a pair of IR cameras placed on either side of a smart glass. The gaze predictor ML model predicts distance at least one gazed object positioned from eye of each subject during systematic execution of a set of tasks. From each pupillary information of each pupil a set of features are extracted which are utilized to classify the gazed object of the subject based on the distance into at least one of a near class, an intermediate class, and a far class.

  • Publication number: 20250108512
    Abstract: This disclosure relates to system and method to reconstruct human motion for mobile robot teleoperation using shared control. The method of the present disclosure acquire an input feed of a human operator to perform a task with assistance in a remote environment using shared control. The mobile robot reconstructs to follow a trajectory of the human operator towards the intended goal in the remote environment. The mobile robot determines at least one goal intended by the human operator based on a previously occurred state, a current kinematic state and a future trajectory of the human operator and a known position of the plurality of goals. The model predictive control generates at least one instruction to control the movement of the mobile robot to perform at least one of following the trajectory of the human operator and reaching the operator intended goal based on a joint angle position and a velocity.
