Robot Mules, Birds and Snakes Helping on the Warfront
From drones and other surveillance bots, to robotic surgeons and payload carriers, robots are lending a helping hand to military forces in many countries. But it will be long, or never, before these replace man on the warfront. After all, they have neither heart and mind, nor any reason to fight
Kits That Maketh Robots
Robots are making their presence felt. These indomitable marvels are not just confined to high-tech labs but being created in our own drawing rooms—thanks to robotic kits
Servo Motor Tester
When using a servo motor in a project, if the servo motor does not respond as per the input, how to make sure that the fault is not in the servo motor but the circuit or logic?
