The robot exhibit is open at the Carnegie Science Center. Its very entertaining. Besides having neat statutes of famous scifi robots, there are many interactive exhibits to demonstrate what real world robots can do. there's also a history of robotics (both real and scifi) on the back wall. We should go and check it out. I happen to have a membership which allows me to bring in up to eight guests for free This might be a November activity though, since most folks seem a bit busy in October. EDIT: Saturday, November 7. Meet in the front lobby at 11 AM.
