Example of obstacle avoidance using sensors. One of the most common approaches to obstacle avoidance is the use of various sensors, such as ultrasonic , LiDAR , radar , sonar , and cameras . These sensors allow an autonomous machine to do a simple 3 step process: sense, think, and act.
The robot moves towards the goal until an obstacle is encountered. Follow a canonical direction (clockwise) until the robot reaches the location of initial encounter with the obstacle (in short, walking around the obstacle). The robot then follows the obstacle's boundary to reach the point on the boundary that is closest to the goal.
The components of a mobile robot are a controller, sensors, actuators and power system. [3] The controller is generally a microprocessor, embedded microcontroller or a personal computer (PC). The sensors used are dependent upon the requirements of the robot.
The velocity obstacle VO AB for a robot A, with position x A, induced by another robot B, with position x B and velocity v B.. In robotics and motion planning, a velocity obstacle, commonly abbreviated VO, is the set of all velocities of a robot that will result in a collision with another robot at some moment in time, assuming that the other robot maintains its current velocity.

Lane change assistance helps the driver through a safe completion of a lane change by using sensors to scan the vehicle's surroundings and monitor the driver's blind spots. [43] When a driver intends to make a lane change, the vehicle will notify the driver through an audio or visual alert when a vehicle is approaching from behind or is in the ...
In robotics motion planning, the dynamic window approach is an online collision avoidance strategy for mobile robots developed by Dieter Fox, Wolfram Burgard, and Sebastian Thrun in 1997. [1] Unlike other avoidance methods, the dynamic window approach is derived directly from the dynamics of the robot, and is especially designed to deal with ...

Robot sensing includes the ability to see, [1] [2] [3] touch, [4] [5] [6] hear [7] and move [8] [9] [10] and associated algorithms to process and make use of environmental feedback and sensory data. Robot sensing is important in applications such as vehicular automation, robotic prosthetics, and for industrial, medical, entertainment and ...
