Obstacle Avoidance with Kinetic Energy Buffer [PDF]
2021 IEEE International Conference on Robotics and Automation (ICRA), 2021 This paper presents Kinetic Energy Difference (KED) as a metric for collision proximity. The calculation of KED for differentially driven robots is explained, along with an example obstacle avoidance algorithm that utilizes it. This example algorithm is computationally efficient and simulations show that it is capable of guiding robots with slow ...

Trajectory generation for road vehicle obstacle avoidance using convex optimization [PDF]
, 2010 This paper presents a method for trajectory generation using convex optimization to find a feasible, obstacle-free path for a road vehicle. Consideration of vehicle rotation is shown to be necessary if the trajectory is to avoid obstacles specified in a ...

Obstacle Avoidance of Semi-Trailers Based on Nonlinear Model Predictive Control
World Electric Vehicle Journal, 2019 Obstacle avoidance is a core part of the autonomous driving of off-road vehicles, such as semi-trailers. Due to the long length of semi-trailers, the traditional obstacle avoidance controller based on the circumcircle model can ensure that there is no ...

Online Learning for Obstacle Avoidance
CoRR, 2023 We approach the fundamental problem of obstacle avoidance for robotic systems via the lens of online learning. In contrast to prior work that either assumes worst-case realizations of uncertainty in the environment or a stationary stochastic model of uncertainty, we propose a method that is efficient to implement and provably grants instance-optimality

Obstacle Avoidance of Multi-Sensor Intelligent Robot Based on Road Sign Detection
Sensors, 2021 The existing ultrasonic obstacle avoidance robot only uses an ultrasonic sensor in the process of obstacle avoidance, which can only be avoided according to the fixed obstacle avoidance route. Obstacle avoidance cannot follow additional information.

A new Cucker-Smale flocking model based on directional limit-cycle
四川大学学报. 自然科学版, 2021 This paper aims at the obstacle avoidance problem for swarm in a multi-obstacle environment. Based on the improved Cucker-Smale swarm motion model and limit-cycle obstacle avoidance algorithm, we propose a new CS flocking model. In this model, we improve

Simulation of obstacle avoidance robots
Global Journal of Research in Engineering and Technology, 2022 The first function of the system is to detect the presence of obstacles. When the user activates the system using the power ON/OFF switch, the Arduino microcontroller will read the data. When the ultrasonic sensor detects the presence of an obstacle in the process of moving forward, the robot will move backward. If the robot does not sense any obstacle,
