Engineers create school of robotic fish that can coordinate their movements

Daily Mail - Science & tech

A school of robotic fish that are able to coordinate their movements underwater - just like real fish - have been created by a team of engineers. Harvard University experts created the fish-inspired bots to work without any external control, mimicking the collective behaviours groups of fish demonstrate. Schools of fish exhibit complex, synchronised behaviours that help them find food, migrate and evade predators with no one fish coordinating the movements. The robotic fish can synchronise their movements like a real school of fish, without any external control - the first time this complex behaviour has been show in robots. The team say in future a similar swarm of robotic fish could be deployed to perform environmental monitoring and search in fragile environments like coral reefs.

NYPD robo-dog 'Digidog' investigates hostage situation in the Bronx

Daily Mail - Science & tech

Residents in the Bronx, New York stopped dead in their tracks as a four-legged robotic dog trotted down East 227th Street Tuesday. The machine, called Digidog, was accompanying human officers responding to a home invasion and barricade situation. Digidog joined the New York Police Department last year, which changed the machine's yellow color to blue and black and gave it a new name - it was initially named'Spot' by its creators Boston Dynamics. The robotic dog, according to reports, was sent inside a building in the Bronx to climb stairs and investigate an area for a hostage situation – but no one was found. The videographer, Daniel Valls of, said the dog responded to a home invasion and barricaded situation on East 227th Street near White Plains Road in Wakefield. Digidog was designed for emergency situations that would otherwise be too dangerous for human officers.

Smart Streetlights which use FACIAL RECOGNITION raise concerns in San Diego

Daily Mail - Science & tech

What began as a way to increase public safety has turned into a civil rights concern. Some residents of San Diego, California are demanding the removal of some 4,000 'Smart Streetlights' which they claim are an invasion of privacy. The devices use sensor nodes to gather a range of information, such as weather and parking counts, but also uses facial recognition technology to count pedestrians. Some residents of San Diego, CA are demanding the removal of some 4,000 'Smart Streetlights' which they claim are an invasion of privacy. The San Diego City Council approved the installation of the Smart StreetLights in December 2016 - and now approximately 4,200 are in place.

Privacy faces risks in tech-infused post-pandemic workplace

The Japan Times

Washington – People returning to the office following the pandemic will find an array of tech-infused gadgetry to improve workplace safety but which could pose risks for long-term personal and medical privacy. Temperature checks, distance monitors, digital "passports," wellness surveys and robotic cleaning and disinfection systems are being deployed in many workplaces seeking to reopen. Tech giants and startups are offering solutions that include computer vision detection of vital signs to wearables that can offer early indications of the onset of COVID-19 and apps that keep track of health metrics. Salesforce and IBM have partnered on a "digital health pass" to let people share their vaccination and health status on their smartphone. Clear, a tech startup known for airport screening, has created its own health pass which is being used by organizations such as the National Hockey League and MGM Resorts.
