Is "robotics" even a relevant market category to invest in? It seems either too broad (factory automation, home auto, toys, etc.) to be have enough depth of knowledge, or too narrow to provide a large enough opportunity. How large do most robotics toys companies get? I think a more relevant question is about agile hardware as the future of manufacturing - which could be called an industrial revolution. Doing hardware (whether electronics, robotics, mechatronics, or pure plastic) on the cheap. The equipment and skills to make robotics companies are still very relevant to all hardware. If anyone hasn't seen the open hardware "Million Dollar Baby" Ignite video - you can see the future of agile (not just open) hardware is being enabled right now. http://vimeo.com/11407341 http://vimeo.com/11407341
