Design and implementation of line follower and obstacle detection robot

Abstract

<p>In this paper, we propose a method for a line follower robot based on the instantaneous computation of the radius of curvature of this line, using infrared line sensors. The number and layout of its sensors, as well as the method chosen, play an important role in the robot's response to the line, with the desired accuracy and speed. In addition, the robot must be equipped with an anti-collision system, using an ultrasonic distance sensor, to detect and avoid obstacles in several situations, especially at line crossovers, when other robots share a common complex line.</p>

A new motion structure for a six-legged insect robot with Bluetooth remote-control

“…The logarithmic sensitivity is derived using the partial derivative of the objective function's logarithm with respect to the element's logarithm, as given in (3). Because these derivatives cannot be calculated analytically, they are tackled using the finite center difference method, that is, dependent on Taylor series, as given in (4).…”

“…Robots exist in industry (e.g., welding, assembly, and painting) as well as healthcare (e.g., surgery, drug delivery, and sample transfer). They also can be used in fires fighting, discovered and defused explosives, and explored space [3][4][5][6][7].…”
