Wakamaru
      The Wakamaru is the first human-size robot that can provide companionship, or function as a caretaker and house sitter.[3] The Wakamaru was created in Japan, and will be for sale there for about one million yen ($14,250).[4] The Wakamaru moves around on wheels, is 3.3 feet tall, weighs 60 pounds, and recharges itself when batteries run low.

The Wakamaru can be programmed to call or e-mail a designated person, hospital, or security firm if it notices a problem. It features continuous access to the Internet, and is equipped with voice and face recognition capabilities that allow the robot to search for and follow faces and movement. It has the ability to comprehend and interact with humans, and also comes with a built-in-dictionary, making it able to recognize 10,000 words.

The Wakamaru promises to be an ideal help for elderly people, the disabled, or others that are living independently.  However, with a price tag of almost $15,000, few people, especially elderly can afford such a luxury.  The Wakamura is also large and could possibly injure or kill an elderly person if something went wrong.
