Lithography‐Compatible Conductive Metal–Organic Frameworks for Scalable Electronics

Advanced Materials, EarlyView.
Conductive MOF thin films are integrated as gate electrodes in semiconductor devices through a photolithography‐compatible patterning strategy. CVD‐grown 2D MOF thin films enable stable operation across bottom‐gate MoS2/MoTe2 field‐effect transistors and top‐gate IGZO arrays, highlighting the potential of conductive MOFs as functional electronic ...

Soft and Transient Bioelectronics Enabled by Polymer‐Free Ti3C2Tx MXene Hydrogels

Advanced Materials, EarlyView.
We present Ti3C2Tx MXene hydrogel (MXgel) bioelectronics, a soft, flexible, and fully transient platform for high‐fidelity neural recording and stimulation. MXgel bioelectronics exhibit exceptional electrical conductivities, low electrochemical impedances, and high charge injection capacities.

Planning constrained motion

Proceedings of the twentieth annual ACM symposium on Theory of computing - STOC '88, 1988
We consider the motion planning problem for a point constrained to move along a path with radius of curvature at least one. The point moves in a two-dimensional universe with polygonal obstacles. We show the decidability of the reachability question: “Given a source placement (position and direction pair) and a target placement, is there a curvature ...

Kinodynamic motion planning

Journal of the ACM, 1993
Summary: Kinodynamic planning attempts to solve a robot motion problem subject to simultaneous kinematic and dynamics constraints. In the general problem, given a robot system, we must find a minimal-time trajectory that goes from a start position and velocity to a goal position and velocity while avoiding obstacles by a safety margin and respecting ...

Motion planning with uncertainty

Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002
We present a general framework for motion planning of robots in the presence of obstacles and other robots. We use variational calculus and optimization to find optimal open loop and closed loop plans in the presence of uncertainty. The plans are based on world models with set-valued uncertainty associated with the positions and shape of the obstacles.

Multiworld Motion Planning

IEEE Robotics and Automation Letters, 2018
While predictive planning approaches have had broad success in robot navigation, most implementations of them have important limitations. In particular, they plan around a single predicted outcome (plus uncertainty) or the union of several likely outcomes. Here, we introduce the multiworld motion planning problem, where a robot plans around each likely

Motion planning for the Snakeboard

The International Journal of Robotics Research, 2012
This paper provides an analytical solution to the motion-planning problem for the Snakeboard. Given a desired planar trajectory in the fiber space, an explicit solution is computed for the controllable inputs in the base space that locomote the Snakeboard along a given trajectory. The motion-planning problem or gait generation problem is solved for the

Motion Planning: Recent Developments

2006
A key trait of an autonomous robot is the ability to plan its own motion in order to accomplish specified tasks. Often, the objective of motion planning is to change the state of the world by computing a sequence of admissible motions for the robot.

Multiscale motion planning

Proceedings 1997 IEEE International Symposium on Computational Intelligence in Robotics and Automation CIRA'97. 'Towards New Computational Principles for Robotics and Automation', 2002
Multiscale planning is introduced as a nested system of state space search processes which provide for exceptionally efficient computational algorithms. It is demonstrated that search in the output space allows for efficient planning/control procedures. The results of 2-level nested hierarchical planning are given as a representative simulation example.

Kinodynamic motion planning

SMC'03 Conference Proceedings. 2003 IEEE International Conference on Systems, Man and Cybernetics. Conference Theme - System Security and Assurance (Cat. No.03CH37483), 2004
This paper addresses the problem of kinodynamic motion planning for a non-holonomic bicycle system moving on a 2D plane in minimum time. As a solution to this optimization problem, we propose an algorithm for determining feed-forward control values, which in the absence of disturbances and uncertainties, provide a plan to move a system from an initial ...
