The debate published in ieee spectrum between Colin Angle (iRobot) and Robert Bauer (Willow Garage) is interesting. Willow garage has benefited the community greatly and it’s pretty easy to get a robot to grasp a cup using the ROS platform (given you can purchase the robot). This approach of crowdsourcing does speed up the development but it’s not easy to build a hardware business out of this model. Do write your thought in the article. It will be interesting to see where this goes.
