Manta ray inspires underwater robot

Singapore has trialled patrol robots that blast warnings at people engaging in "undesirable social behaviour", adding to an arsenal of surveillance technology in the tightly controlled city-state.

In recent days, two former African presidents have been the targets of fake news. In DR Congo, a photo of Joseph Kabila has been circulating with the claim he stood alongside the former head of the rebel group ADF, which has links with the Islamic State group. Another video, meanwhile, purports to show a crowd of supporters of Alpha Condé gathering in Paris... although the man they are shouting in support of is not the ousted Guinean president and it wasn't filmed in Paris at all.

Following revelations by whistleblower Frances Haugen and a global outage, the US company faces renewed scrutiny. It could mark a tipping point and prompt lawmakers to get tough on the tech giant.

Users have been facing issues accessing the social media giant's apps and services for the second time in a week. The company said a configuration change was behind the outage, which is under control.

Facebook is facing a historic crisis. Revelations by former data scientist-turned-whistleblower Frances Haugen have shed light inside the notoriously secretive tech giant.

US cyber defense capabilities are at "kindergarten level" in some government departments, the Pentagon's former chief software officer told a British newspaper.

Researchers in California unveiled a bipedal robot on Wednesday (October 6) that combines walking with flying to create a new type of locomotion, allowing it to jump, skateboard and walk on a slackline. The robot, named LEONARDO or LEO for short, was developed by a team at the California Institute of Technology's Center for Autonomous Systems and Technologies. Researchers said LEO is the first robot to use multi-joint legs and propeller-based thrusters to enable it to balance and carry out complex movements.

Caltech researchers have built a bipedal robot that combines walking with flying to create a new type of locomotion, which makes it more agile and capable of complex movements. Part walking robot, part flying drone, the LEONARDO (short for LEgs ONboARD drOne, or LEO for short) can walk on a tightrope like tightrope walkers, jump, and even skateboard. Developed by a team from Caltech’s Center for Autonomous Systems and Technologies (CAST), LEO is the first robot to uses multi-jointed legs and propeller-based thrusters to achieve a good degree of control over its balance.
