Rolling line: Train Signals explain and fix for a map

Intellectual Sagar on Instagram: "This video shows a line-following robot—one of the simplest yet most important ideas in robotics. A black line on paper acts as the guide. Sensors beneath the robot detect the contrast between the dark path and the light surface. Based on this input, the controller instantly adjusts the speed of each wheel, keeping the robot centered on the line through constant real-time corrections. The same logic powers real systems you see every day: factory automation, ware
