Autonomous Quad Rotacaster Omni-Bot
posted September 8 2010 16:30.14




About a month ago we presented R J McNamara's attempt to build an Omni-wheeled Bot, what that robot was lacking was the Rotacaster Omni-wheels cause the Rotacaster wheels did not existed in Lego Technics format.
Now this is changed and a new robot R J made, is equiped with 4 sets of the new wheels allowing it to move and manuever in any direction smoothly that you forget the 4x Ultrasonic Sensors to aid in navigation.
For more info here is the place to look.

Aggressive Maneuvers for Autonomous Quadrotor Flight
posted June 1 2010 14:40.34




Daniel Mellinger from the University of Pennsylvania describes one of his works as "developing controllers for aggressive maneuvers with quadrotor helicopters". In action this means tremendous maneuverability and insane control in turning.
Perching seems simple compared to the double flips and the amazingly precise flight through windows. A UAV showing things to come, enjoy.
