Dubins-Laser system optimal trajectory analysis.
Resumé
The study focuses on motion planning for a Dubins vehicle with a controllable laser. It formulates a novel planar motion planning problem, characterizes properties of the optimal trajectory, and provides numerical insights. The research aims to determine a time-optimal trajectory for the Dub-L system to capture a static target efficiently.

Statistik
ω∗(t) = −ωM, if pψ(t) > 0
H1(x, u, p, p0) = p0 + px(t) cos(θ(t)) + py(t) sin(θ(t)) + (pθ(t) + pψ(t))u(t)ρ
Numerous variations [11], [18]–[21] of the optimal control problem studied in [13] have been extensively studied including obstacle avoidance [16], [22], [23], path planning [24], intercepting targets [25], [26], target tracking [27], [28], and coverage problems [29].

"From an arbitrary initial position and orientation, the objective is to steer the system so that a given static target is within the range of the laser and the laser is oriented towards it in minimum time."
"We characterize multiple properties of the optimal trajectory and establish that the optimal trajectory for the Dubins-laser system is one out of a total of 16 candidates."
