Hope this is okay, i had other idea, but i really like P-body's design.
Appearance:http://www.gamerscripts.com/college_demo/portal2/pbody.htm
Name:P-Body.
Age: Assumed to be less than a year.
Gender: None.
Canon: Portal 2.
Personality: A quirky robot, and at the best of times, possessing the intelligence of a 5th grader.
Short Bio: P-Body was made to test various devices inside of aperture laboratories, originally made by GLaDOS from a old calculator she had lying around the facility, this robot and its companion Atlas were needed to satisfy GLaDOS's built-in desire for testing and knowledge gathering after all the human test subjects at the facility died do to "unknown" circumstances.
Abilities: P-body was built to have all the latest and greatest software a calculator could have, with legs being equipped with long fall boot technology, negating the possibility of fall damage and landing on any part of the body other than feet. P-Body is also equipped with all the latest tax calculator needs. Perfect for the accountant on the go.
Equipment: P-Body is also equipped with an Aperture Science Portable Quantum Tunneling Device, which unfortunately does no good unless the area is covered in moon rock dust. Aside from its sturdy metal body and long fall boots, there is little useful in this robot.
