The build relies on the classic Arduino Uno microcontroller, which talks to a HC-SR04 ultrasonic sensor module and two infrared sensors in order to track a human target and follow it around.

By his own recollection, the teen has always enjoyed building things, though his previous projects were usually completed over a weekend. The robotic hand was a six-month endeavor created through ...

Unlike traditional robot grippers, the MOTIF Hand is multimodal, meaning it can gather and respond to several types of sensory input at once. That includes pressure, temperature, and even motion.

Eventually, you try your hand at making your own custom projects and publishing your own tutorials. Few are lucky to have a first-project as elaborate as [Greg06’s] quadruped robot.
