The 4 foot 9 robot, which weighs in at approximately 148 pounds, has built-in artificial intelligence (AI) that equips it with a variety of skills. Mahru comes with an advanced motion capture system, for instance, which allows it to mimic common actions like arm waving. Like a human, it can also move its lips, eyebrows and pupils, and when it walks, Mahru is able to pull its hands away from any obstacles. Even better, the robot is programmed to recognize human voices, walk to specific places on demand and respond to simple phrases like: "What is your name?" and "How tall are you?" The latest variant of the robot (Mahru-M) has sensors that can differentiate between faces and objects and deliver things to humans on demand, but is limited to a tricycle wheel to move about.
