Cassie Cal robot can probably ride hovershoes better than you

The SpotMini, for example, has been performing feats of strength every few months. UC Berkeley’s Hybrid Robotics Lab is adding its bipedal robot, Cassie Cal, to the mix. The researchers are teaching Cassie to ride motorized single-wheel skates, or hovershoes, IEEE Spectrum Magazine reported Thursday. The skates are pretty hard to operate, even for a human. In addition to balancing, you control the skates by leaning forward, backward, left and right. The researchers added a sensor to Cassie to help with control.Shuxiao Chen, Jonathan Rogers, and Bike Zhang, UC Berkeley students who worked on the project, said it took about eight months to teach Cassie to skate. The process involved mathematical models, simulations to test the algorithms and figuring out how to interface and communicate with Cassie and various sensors. In short: lots of trial and error. The team said the larger goal is to teach robots to achieve multi-modal locomotion, which humans are capable of. Optimizing locomotion for legged robots, according to the team, would improve travel efficiency over various terrains. “Autonomous robots with multi-modal locomotion capabilities can have a big impact in the real-world from food delivery to security and surveillance to search and rescue missions,” the team said. Originally published June 7.Update, June 10: Adds comments from UC Berkeley student team.

Distant dead planet could tell how world will end study says

Weiss; X-ray spectrum: NASA/CXC/MIT/H. M.GüntherStudying a dead distant planet could help humans to know more about the way in which Earth will finally die and perish, a new study report published in the journal Science says. Recently, researchers while monitoring a distant star in deep space stumbled upon an orbiting fragment of a dead, shattered planet, and experts believe that this could be actually a preview of Earth’s inevitable fate in the future.The study report claimed that the discovery of this planetary fragment orbiting around a white dwarf could shed light into the twilight years of planetary systems. Experts believe that the newly found planetary chunk could be actually a piece of the planet’s shattered core. Scientists also speculate that the planet might have perished brutally during the star’s death throes.Researchers also revealed it is quite remarkable that the dead planet’s fragments survived the extremely intense gravity of the white dwarf star.”The white dwarf’s gravity is so strong — about 100,000 times that of the Earth — that a typical asteroid will be ripped apart by gravitational forces if it passes too close,” said Christopher Manser, lead author of the study and a physicist at the University of Warwick in Coventry, England, said in a statement.The study report suggested that the planetary chunk might be orbiting around the star every two hours, and no larger than 250 miles in diameter to avoid being ripped apart by the white dwarf’s gravitational force.Scientists also revealed that both the dead star and the planetary chunk are located in our Milky Way, at a distance of 410 light years away from the Earth.Experts believe that Earth could also face a similar fate when the sun swells into a red giant. As the sun swells, it will consume Mercury, Venus, and Earth, and will later shrink turning into a white dwarf.last_img read more

Success for local OffRoad racing team in Wales

The place is now considered an international motorsport complex where other important competitions take place. The Welsh Round, part of the World Rally Championship, the RAC Rally and the Wales Rally, a round of the British Rally Championship all are organised at Walters Arena.Zahra and Cassar drove for more than 150 kilometres, divided into 10laps of at least 15 kilometres each, all laps offering huge obstacles, with the intent to deprive points to participating teams that at the same time are racing against time.The only Maltese team competing, Pitass Engineering Off-Road Racing Team competed against 40 teams, being the maximum accepted by the organisers and finished in the prestigious second place.WhatsApplast_img read more
