A Third-order Differential Steering Robot And Trajectory Generation In The Presence Of Moving Obstacles
… thesis, four robots will be used to implement a collision-free trajectory planning/replanning algorithm. The existence of a chained form transformation so that the robot's model can be control in canonical form will be analyzed and proved. A trajectory generation for obstacles avoidance will be …

Low-latency trajectory planning for high-speed navigation in unknown environments
… A minimum-time, state and input constrained trajectory is generated for each cluster until a collision-free trajectory is found (if one exists). Relaxing position constraints reduces the planning problem to finding the switching times for the minimum-time optimal solution, something that can …

A homotopy-based hierarchical framework for semi-autonomous/autonomous vehicle navigation
… enabling a divide-and-conquer strategy. In a collision-free trajectory generation problem, the presence of obstacles serves to creating discontinuities in the set of feasible trajectories. However, the complexity can be reduced significantly if we independently consider multiple distinct …

Navigation in unknown environment by building instantaneous spatial structures
… time it senses obstacles and reacts to achieve a collision free trajectory. In both cases the robot circumnavigates obstructions and generates a new path from the initial location to the goal point. Often the strategies used for navigation employ simple path planning techniques aided by specific …

Threat Assessment and Proactive Decision-Making for Crash Avoidance in Autonomous Vehicles
… to generate the probabilistically safest trajectory. This approach can be instrumental in the near-crash scenarios where no collision-free trajectory exists. Three different driving behaviors are considered: Normal, Aggressive, and Drowsy. Hidden Markov Models are used for driver behavior …

Decentralized Multiagent Trajectory Planning in Real-World Environments
… aerial vehicle (UAV) applications, multiagent trajectory planning plays an indispensable role. The applications encompass search and rescue missions, surveillance, package delivery, and more. Each of these scenarios necessitates intricate coordination amongst multiple UAVs, driving the need for …

Robotic Offline Path Planning
… used for offline robots to build more efficient collision-free trajectories in terms of the length in more skilled fashion. Robotic path planning as one of the most important problems has been under investigation by a variety of researchers within the last few decades. Path planner refers to a …
