Sensors in Robotics: How Ultrasonic, LiDAR, and IMU Work
Sensors are to robots what eyes, ears, and skin are to humans—but with far fewer limits. While we rely on just five senses, robots can be equipped with many more, sensing distances, movement, vibrations, orientation, light intensity, and even chemical properties. These sensors form the bridge between the digital intelligence of a robot and the physical world it operates in.

Debugging a Robot In Simulation Before You Burn Wires
Hardware does not come with an undo button. Once you power it on, mistakes—from reversed wiring to faulty code—can result in costly damage. Motors may overheat, printed circuit boards (PCBs) can be fried, and sensors may break. These issues turn exciting projects into frustrating repair sessions. The autonomous drone shown above, designed for GNSS-denied environments in webots as part of the ISRO Robotics Challenge, is a perfect example—where careful planning, testing, and hardware safety were critical at every step
