Emily is a robotic lifeguard that can race across the ocean to help a swimmer in distress.
This is no toy motor boat, but literally, a lifesaver.
Los Angeles County lifeguards are now testing the device to see how Emily can help them during the busy summer beach season.
“Emily is a new device that was created to help contact a conscious victim. So it’s a very good tool if someone is still viable, they’re not unconscious, you can use Emily to go out and get someone,” said Capt. Remy T. Smith of the Los Angeles County Fire Department Lifeguard Division.
UK Dog-owner Nat Morris, 30, has invented a hi-tech way of feeding his dog – by using Twitter.
Morris, an IT consultant, uses an electronic system to give his border terrier Toby a ‘tweet treat’ by sending him a Twitter message to @FeedToby.
Mr Morris spends a lot of time working away from home and isn’t always able to feed four-year-old Toby by hand but, by using his new invention, he can send his dog a treat from anywhere in the world.
He said: ‘Toby absolutely loves it. At first, he didn’t know what was going on.
‘Now he sits underneath, wagging his tail and waiting for the treats to drop.’
And Mr Morris has even rigged up an online camera so he can see Toby eating at his home in Milford Haven, west Wales.
He is considering patenting his system but one problem is that friends and family have been sending tweets to Toby.
‘People have been sending him food at all hours of the day – so I had to limit it to between nine in the morning and nine in the evening,’ he added.
When a tweet is sent, it is received by a mini-computer, and a buzzer sounds alerting Toby. A motor from a small HP printer comes to life and pulls open a trap door which releases a serving of food down a tube and into Toby’s food bowl below.
Researchers at the Polytechnic Institute of New York University have created a robotic fish that have been accepted as leader by real fish:
The researchers designed their bio-inspired robotic fish to mimic the tail propulsion of a swimming fish, and conducted experiments at varying tail beat frequencies and flow speeds.
In nature, fish positioned at the front of a school beat their tails with greater frequency, creating a wake in which their followers gather.
The followers display a notably slower frequency of tail movement, leading researchers to believe that the followers are enjoying a hydrodynamic advantage from the leaders’ efforts.
In an attempt to create a robotic leader, Marras and Porfiri placed their robot in a water tunnel with a golden shiner school.
First, they allowed the robot to remain still, and unsurprisingly, the “dummy” fish attracted little attention.
When the robot simulated the familiar tail movement of a leader fish, however, members of the school assumed the behavior patterns they exhibit in the wild, slowing their tails and following the robotic leader.
The researchers posit that robotic leaders could help lead fish and other wildlife that behave collectively — including birds — away from toxic situations such as oil or chemical spills or human-made dangers such as dams.
