OSRF summarized the demography of DRC teams that used ROS and Gazebo. Is there anything similar overall summary for APC 2015 (that happened just a week prior to DRC)? Since some ROS-based robots such as Baxter research ver, PR2 are offered at the venue I guess ROS-ratio can be already high, but it's still interesting to see the coverage.

(I did some research) 2nd place MIT uses Drake on ABB, 3rd place team Grizzly clearly uses ROS.
