LEONARDO, the Bipedal Robot, Can Ride a Skateboard and Walk a Slackline

10-06-21

Researchers have built a bipedal robot that combines walking with flying to create a new type of locomotion, making it exceptionally nimble and capable of complex movements. "We drew inspiration from nature. Think about the way birds are able to flap and hop to navigate telephone lines," says Soon-Jo Chung, Bren Professor of Aerospace and Control and Dynamical Systems; Jet Propulsion Laboratory Research Scientist. "A complex yet intriguing behavior happens as birds move between walking and flying. We wanted to understand and learn from that." A paper titled "A bipedal walking robot that can fly, slackline, and skateboard" about the LEO robot was published online on October 6 and was featured on the October 2021 cover of Science Robotics.

Dabiri Appointed to President's Council of Advisors on Science and Technology

09-22-21

President Joe Biden has announced the appointment of John O. Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, to the President's Council of Advisors on Science and Technology (PCAST). Presidents have established advisory committees of scientists, engineers, and health professionals ever since Franklin D. Roosevelt created his Science Advisory Board in 1933. "We're here to provide whatever input the president needs," Dabiri says. "My understanding is that we'll be meeting pretty frequently, as the president wants science to be a big part of his decision-making process." [Caltech story]

Mice Can Learn Much Faster than Previously Thought

09-01-21

Researchers have now conducted a study in which they measured how mice navigate a complicated labyrinth, suggesting a new framework with which to study complex animal behaviors and learning. The mice rapidly learned how to navigate this unfamiliar environment about 1,000 times faster than mice generally learn simple yet unnatural tasks. The research is a collaboration between the laboratories of Markus Meister, Anne P. and Benjamin F. Biaggini Professor of Biological Sciences, and Pietro Perona, Allen E. Puckett Professor of Electrical Engineering. [Caltech story]
