    Abstract: A bidirectional haptic feedback system, including: a flexible membrane configured to be mounted on a handheld controller; sensor-actuator units arranged on the flexible membrane, the sensor-actuator units respectively including a damping mechanism configured to mechanically isolate vibrations between adjacent sensor-actuator units; a control system configured to: generate vibration signals within selected frequency bands within a proximity to a natural resonant frequency range of the sensor-actuator units to drive the actuators of the sensor-actuator units to deliver haptic feedback to a user based on a state of the robot; simultaneously detect user grasp contact and pressure through analysis of back electromotive force (EMF) signals generated by the sensor-actuator units; and adjust robot control parameters dynamically in response to the detected grasp contact and pressure.

    Abstract: A system for human-cobot (collaborative robot) ergonomic interaction, including: a communication interface operable to receive sensor data related to human motion; ergonomic assessment processor circuitry operable to evaluate the sensor data to generate a strain score for at least one human joint, wherein the strain score represents a strain level of the at least one human joint based on an integration of motion of the at least one human joint over a period of time; human intent prediction processor circuitry operable to interpret the sensor data to predict an object the human intends to grasp, and to select a destination container for the predicted object; and cobot motion processor circuitry operable to determine a position or orientation for the cobot to place the selected destination container based on the predicted object and the strain score.

    Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to improve spatial-temporal data management. An example apparatus includes a hypervoxel data structure generator to generate a root hexatree data structure having sixteen hypernodes, an octree manager to improve a spatiotemporal data access efficiency by generating a first degree of symmetry in the root hexatree, the octree manager to assign a first portion of the hypernodes to a positive temporal subspace and to assign a second portion of the hypernodes to a negative temporal subspace, and a quadtree manager to improve the spatiotemporal data access efficiency by generating a second degree of symmetry in the root hexatree, the quadtree manager to assign respective hypernodes of the positive temporal subspace and the negative temporal subspace to respective positive and negative spatial subspaces.
