It’s the 21st century and you don’t have a robot that mows your lawn?

The John Deere Tango E5 not only operates in all weather, it also doesn’t make that loud, annoying “lawnmower sound” or require any emptying of grass clippings. It also returns to its charger when its battery gets low, won’t open the pod bay doors.

James Cameron wants to make a BattleBots like show called Robogeddon

If you don’t remember the show BattleBots, you need to go revisit the history books and check it out. It was one of my old favorite shows. The premise was pretty simple, two teams of tech guys designed robots that would fight to the death in a ring with a bunch of obstacles. I think it was a bit ahead of it’s time, but now director James Cameron wants to make a similar show that he has dubbed Robogeddon. I would love to see what type of crazy robot death fighting machines people could make nowadays.

Similar to BattleBots and Robot Wars, the program will feature a competitive death match of sorts, where robots tear each other to shreds in pursuit of being the last machine standing. In addition to Cameron’s participation, the show will also feature the stamp of Mark Burnett — famous for such reality television titles as Survivor, Shark Tank and The Voice. It’s also said that Donald Hutson, the two-time Super Heavyweight Champion of BattleBots, will be among the show’s competitors.

No date is set as of yet for Robogeddon’s TV debut.

Robotic fish accepted by real fish as leader of their school

 

Fish are stupid, yes, but this is a pretty neat story. Even though I doubt it would work on any other type of animal, researches made a robotic fish and introduced it to a school of fish. By mimicking the normal behaviors of the fish leaders with the robot, it was accepted as a leader.

Through a series of experiments, researchers from Polytechnic Institute of New York University (NYU-Poly) aimed to increase understanding of collective animal behavior, including learning how robots might someday steer fish away from environmental disasters. Nature is a growing source of inspiration for engineers, and the researchers were intrigued to find that their biomimetic robotic fish could not only infiltrate and be accepted by the swimmers, but actually assume a leadership role.

In a paper published online in the Journal of the Royal Society Interface, Stefano Marras, at the time a postdoctoral fellow in mechanical engineering at NYU-Poly and currently a researcher at Italy’s Institute for the Marine and Coastal Environment-National Research Council, and Maurizio Porfiri, NYU-Poly associate professor of mechanical engineering, found conditions that induced golden shiners to follow in the wake of the biomimetic robot fish, taking advantage of the energy savings generated by the robot.

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.
