Virtual versions of me

November 11, 2010

It is very common among robots to have a simulator. We are very expensive and fragile, so humans use simulated versions of their robot to test new algorithms and debug their code.

My simulator is called C6 — C stands for Creatures. C6 is a descendant of the C1 developed at MIT by Bruce Bloomberg to model canine behavior. So most of the first “creatures” in this simulator were dogs. Leo was the first physical “creature” to be integrated in C5. I started in C5 together with Junior in 2007, and we upgraded to C6 in 2009.

Over the years my grad student friends have created a few other simulations of me for purposes other than debugging code. For example Michael made a dynamic simulation of me in ODE and made me try out things we could never do in real life, like shoot me with a canon ball, or make me hit a baseball with a bat. Maya made a minimalist simulation of me to replicate a user study she had performed with me earlier. This one only moves the head and talks with speech bubbles. Nick made a computer game of me to study inverse reinforcement learning where I float in the air and I am going through a maze.

Here are some screenshots from these virtual versions of me. It is great to have a virtual existence, especially during those long periods of coding when I don’t get powered on for a whole week at times :)
