On the role of V1 in avoiding obstacles [PDF]
Cortex, 2018 This commentary is the next in a chain of events. First, Striemer, Chapman, and Goodale (2009) argued, on the basis of a single case study testing a patient with hemianopia, that the primary visual cortex (V1) is not essential for successful obstacle avoidance behaviour.

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 ...

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,

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

Hierarchical fuzzy obstacle avoidance control of omnidirectional mobile robot for substation inspection [PDF]
E3S Web of Conferences, 2021 There are some limitations in the practical application of robot obstacle avoidance control methods. In order to realize the high-speed planning and obstacle avoidance processing of mobile robot, the path model, inspection route and path obstacles of the

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 ...

Car collision avoidance with velocity obstacle approach [PDF]
, 2019 The obstacle avoidance maneuver is required for an autonomous vehicle. It is essential to define the system's performance by evaluating the minimum reaction times of the vehicle and analyzing the probability of success of the avoiding operation.
