I like the innovative approach! I wonder what other types of nature mimicing behavoirs could be used? The side to side swing is very effective, especially using the battery as the pendulum weight. I wonder how effective a many legged approach would be such as a millipede or centipede? It is late summer here and I am still fighting with the ants, they are fast and very able to cover vertical and inverted surfaces. I would love to see something with multiple legs both for speed and to determine efficiency.
Biology continues to provide valuable insights to engineering at all scales from neural data storage, to the interference pattern colors of butterfly wings, to unexpected sensory capabilities, to efficient means of locomotion and flight. There may be unexpected benefits of the time that children spend observing nature on idle afternoons..
It amazes me how far we have gone in robotics in just a matter of a decade. the ROCR is a cute climber but I still like its predecessors more: The RiSE, from boston dynamics' http://www.youtube.com/watch?v=Zs6XmmyfQKQ

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
