Abstract: An automated design method, and corresponding computer system for implementing such a method and robot mechanism with an optimized flexible link, that is configured to optimize a desired load-displacement behavior of planar flexible-link mechanisms at expected points of interaction. To implement the new design method, a subset of rigid links of an existing rigid-link robot mechanism are replaced with flexible links, optimizing their rest configurations. The efficacy of the design approach has been proven with two fabricated prototypes of robot mechanisms, with one being adapted for grasping tasks and one being adapted for locomotion tasks.

Abstract: A new controller for use in robots with kinematic loops as well as in most other types of robots (such as those with fully actuated kinematic trees). The controller includes an inverse kinematics (IK) module that implements a versatile IK formulation for retargeting of motions, including expressive motions, onto mechanical systems (i.e., robots with loops and/or without loops). Further, the controller is configured to support the precise control of the position and orientation of end effectors and the center of mass (CoM) (such as of walking robots). The formulation of the algorithms carried out by the IK module safeguards against a disassembly when IK targets are moved outside the workspace of the robot. A regularizer is included in the controller that smoothly circumvents kinematic singularities where velocities go to infinity.

Abstract: An automated robot design pipeline facilitates the overall process of designing robots that perform various desired behaviors. The disclosed pipeline includes four stages. In the first stage, a generative engine samples a design space to generate a large number of robot designs. In the second stage, a metric engine generates behavioral metrics indicating a degree to which each robot design performs the desired behaviors. In the third stage, a mapping engine generates a behavior predictor that can predict the behavioral metrics for any given robot design. In the fourth stage, a design engine generates a graphical user interface (GUI) that guides the user in performing behavior-driven design of a robot. One advantage of the disclosed approach is that the user need not have specialized skills in either graphic design or programming to generate designs for robots that perform specific behaviors or express various emotions.

Abstract: A robot control method, and associated robot controllers and robots operating with such methods and controllers, providing computational vibration suppression. Given a desired animation cycle for a robotic system or robot, the control method uses a dynamic simulation of the physical robot, which takes into account the flexible components of the robot, to predict if vibrations will be seen in the physical robot. If vibrations are predicted with the input animation cycle, the control method optimizes the set of motor trajectories to return a set of trajectories that are as close as possible to the artistic or original intent of the provider of the animation cycle, while minimizing unwanted vibration. The new control method or design tool suppresses unwanted vibrations and allows a robot designer to use lighter and/or softer (less stiff) and, therefore, less expensive systems in new robots.

Abstract: Methods and corresponding systems that are useful in design and fabrication of kinetic wire mechanisms or characters. The method includes a computational technique for the design of kinetic wire mechanisms tailored for fabrication on consumer-grade hardware such as a desktop CNC bending device. The method takes as input a skeletal animation of the mechanism to be fabricated and estimates, from the skeletal animation, a cable-driven and compliant wire structure, which matches user-selected keyframes. To enable localized deformations, the technique involves shaping the mechanism's body (i.e., the wire) into functional spring-like entities at a set of locations along the length of the mechanism's body.

Abstract: Techniques for generating locomotion data for animating a virtual quadruped model, starting at an origin point and travelling to a destination point along a defined path. A virtual skeletal structure for the virtual quadruped model is analyzed to identify a torso region, limbs each ending in a respective end effector, and limb attributes. A predefined locomotion template for virtual quadruped characters is retrieved and mapped to the virtual quadruped model by aligning the torso region and the plurality of limbs of the virtual skeletal structure for the virtual quadruped with a second torso region and a second plurality of limbs of the predefined locomotion template. Locomotion data is generated for the virtual quadruped model based on the defined path and by upscaling the mapped predefined locomotion template, based at least on the set of limb attributes determined by analyzing the virtual skeletal structure for the virtual quadruped model.

Abstract: A simulation engine models interactions between a simulated character and real-world objects to produce a physically realistic augmented reality (AR) simulation. The simulation engine recognizes a given real-world object and then identifies, within a library of object models, an object model corresponding to that object. The simulation engine projects the object model onto the real-world object such that the object model is geometrically aligned with the real-world object. When the simulated character encounters the real-world object, the simulation engine models interactions between the simulated character and the real-world object by adjusting the kinematics of the simulated character relative to the object model associated with the real-world object.
