Biologically Inspired Complete Coverage Path Planning Algorithm Based on Q-Learning

Sensors, 2023
Complete coverage path planning requires that the mobile robot traverse all reachable positions in the environmental map. Aiming at the problems of local optimal path and high path coverage ratio in the complete coverage path planning of the traditional ...

Level spacings and periodic orbits [PDF]

Physical Review E, 2001
Starting from a semiclassical quantization condition based on the trace formula, we derive a periodic-orbit formula for the distribution of spacings of eigenvalues with k intermediate levels. Numerical tests verify the validity of this representation for the nearest-neighbor level spacing (k=0). In a second part, we present an asymptotic evaluation for

CONTROL OF IN-ORBIT SPACE MANIPULATION

IFAC Proceedings Volumes, 1985
Abstract Present European and French programs are carried out in the field of space robotics. Considering space applications and special constraints encountered in space environment, various design concepts are discussed. Results of on going research and development efforts in the field of terrestrial manipulator control are considered.

Quantum walk on orbit spaces

Physical Review A, 2023
Inspired by the covering-space method in path integral on multiply connected spaces, we here present a universal formula of time-evolution kernels for continuous- and discrete-time quantum walks on orbit spaces. In this note, we focus on the case in which walkers' configuration space is the orbit space $Λ/Γ$, where $Λ$ is an arbitrary lattice and $Γ ...
