ROBOTIC MANIPULATION METHODS AND SYSTEMS FOR EXECUTING A DOMAIN-SPECIFIC APPLICATION IN AN INSTRUMENTED ENVIRONMENT WITH CONTAINERS AND ELECTRONIC MINIMANIPULATION LIBRARIES
20170348854 · 2017-12-07 ·

This disclosure discloses various technical features for creating robotic humanoid movements, actions, and interactions with tools and the instrumented environment by automatically building movements for the humanoid; actions and behaviors of the humanoid based on a set of computer-encoded robotic movement and action primitives. The primitives are defined by motions/actions of articulated degrees of freedom that range in complexity from simple to complex, and which can be combined in any form in serial/parallel fashion. These motion-primitives are termed to be minimanipulations and each has a clear time-indexed command input-structure and output behavior/performance profile that is intended to achieve a certain function. Minimanipulations comprise a new way of creating a programmable-by-example platform for robots. The minimanipulation electronic libraries provide a large suite of higher-level sensing-and-execution sequences that are common building blocks for complex tasks, such as cooking, taking care of the infirm, or other tasks performed by robots.

Autonomous drones for tactile feedback in immersive virtual reality
09836117 · 2017-12-05 · ·

A “Tactile Autonomous Drone” (TAD) (e.g., flying drones, mobile robots, etc.) supplies real-time tactile feedback to users immersed in virtual reality (VR) environments. TADs are not rendered into the VR environment, and are therefore not visible to users immersed in the VR environment. In various implementations, one or more TADs track users as they move through a real-world space while immersed in the VR environment. One or more TADs apply tracking information to autonomously position themselves, or one or more physical surfaces or objects carried by the TADs, in a way that enables physical contact between those surfaces or objects and one or more portions of the user's body. Further, this positioning of surfaces or objects corresponds to some real-time virtual event, virtual object, virtual character, virtual avatar of another user, etc., in the VR environment to provide real-time tactile feedback to users immersed in the VR environment.

NERVOUS SYSTEM EMULATOR ENGINE AND METHODS USING SAME
20230177283 · 2023-06-08 ·

A nervous system emulator engine includes working computational models of the vertebrate nervous system to generate lifelike animal behavior in a robot. These models include functions representing several anatomical features of the vertebrate nervous system, such as spinal cord, brainstem, basal ganglia, thalamus, and cortex. The emulator engine includes a hierarchy of controllers in which controllers at higher levels accomplish goals by continuously specifying desired goals for lower-level controllers. The lowest levels of the hierarchy reflect spinal cord circuits that control muscle tension and length. Moving up the hierarchy into the brainstem and midbrain/cortex, progressively more abstract perceptual variables are controlled. The nervous system emulator engine may be used to build a robot that generates the majority of animal behavior, including human behavior. The nervous system emulator engine may also be used to build working models of nervous system functions for clinical experimentation.

POINT SET INTERFERENCE CHECK
20230173674 · 2023-06-08 ·

A robot interference checking motion planning technique using point sets. The technique uses CAD models of robot arms and obstacles and converts the CAD models to 3D point sets. The 3D point set coordinates are updated at each time step based on robot and obstacle motion. The 3D points are then converted to 3D grid space indices indicating space occupied by any point on any part. The 3D grid space indices are converted to 1D indices and the 1D indices are stored as sets per object and per time step. Interference checking is performed by computing an intersection of the 1D index sets for a given time step. Swept volumes are created by computing a union of the 1D index sets across multiple time steps. The 1D indices are converted back to 3D coordinates to define the 3D shapes of the swept volumes and the 3D locations of any interferences.
