Obstacle avoidance, in robotics, is a critical aspect of autonomous navigation and control systems. It is the capability of a robot or an autonomous system/machine to detect and circumvent obstacles in its path to reach a predefined destination. This technology plays a pivotal role in various fields, including industrial automation, self ...
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.

The requirements could be dead reckoning, tactile and proximity sensing, triangulation ranging, collision avoidance, position location and other specific applications. [6] Actuators usually refer to the motors that move the robot can be wheeled or legged. To power a mobile robot usually we use DC power supply (which is battery) instead of AC.
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 ...
The following outline is provided as an overview of and topical guide to robotics: . Robotics is a branch of mechanical engineering, electrical engineering and computer science that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing.
Other examples are fly-by-wire systems in aircraft which use servos to actuate the aircraft's control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens. A hard disk drive has a magnetic servo system with sub-micrometer positioning accuracy ...
A servomotor (or servo motor or simply servo) [1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. [ 1 ] [ 2 ] It constitutes part of a servomechanism , and consists of a suitable motor coupled to a sensor for position feedback and a controller ...
All designs consist of two main components: the mechanical arm and the control system. These are typically interconnected by one or two large multi-conductor cables. When two cables are used, one carries power to the servo motors and brakes while the second carries the position feedback for each joint back to the control system.
