Bistable Networks Enable Complex Shape Changes
Advanced Science, EarlyView.Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Applied Sciences, 2017 The problem of inverse kinematics is fundamental in robot control. Many traditional inverse kinematics solutions, such as geometry, iteration, and algebraic methods, are inadequate in high-speed solutions and accurate positioning.

A closed-loop framework for inverse kinematics of the 7-DOF manipulator
, 2016 The 7-DOF redundant manipulator in greatly improves the obstacle/singularity avoidance capability and operational flexibility. Meanwhile, its inverse kinematics problem would be much difficult since it has an infinite number of solutions. This paper uses

Advanced Science, EarlyView.Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

SeqIKPy: a Python package for inverse kinematics in insects [PDF]
SeqIKPy is a Python package for inverse kinematics (IK) calculations in animal bodies with complex joint configurations. The name stands for Sequential Inverse Kinematics in Python, as our method computes joint angles sequentially by performing IK for ...

Advanced Science, EarlyView.Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...

IKDP: Inverse Kinematics through Diffusion Process [PDF]
It is a common problem in robotics to specify the position of each joint of the robot so that the endpoint reaches a certain target in space. This can be solved in two ways, forward kinematics method and inverse kinematics method.

Solving robotic kinematic problems : singularities and inverse kinematics
, 2023 Kinematics is a branch of classical mechanics that describes the motion of points, bodies, and systems of bodies without considering the forces that cause such motion. For serial robot manipulators, kinematics consists of describing the open chain geometry as well as the position, velocity and/or acceleration of each one of its components. Rigid serial

BP networks based trajectory planning and inverse kinematics of a reconfigurable Mars rover
, 2005 The inverse kinematics of series manipulators presents an inherent complexity due to their various structures and kinematics constraints. To a novel reconfigurable Mars rover's arm, the inverse kinematics had been solved by numerical method combined ...
