IFR Stat is going to release their world robotics report 2006. It usually gives an overall picture of the robot world (forecasts, analysis of robot densities, studies on the profitability of industrial robots, service robots). It's mostly about industrial robots (handling, welding, assembly, dispensing...) showing where the big money is.

I looked at that wondering whether some folks works on mecha/robots for amusements parks or art piece using them.
