To make the robot swim, the motor pumps water into two balloon-like chambers in the fishs tail that operate like a set of pistons in an engine."We are excited about the possibility of being able to use a system like this to get closer to marine life than humans can get on their own," said Katzschmann, lead author of the study published in the journal Science Robotics. As one chamber expands, it bends and flexes to one side; when the actuators push water to the other channel, that one bends and flexes in the other direction.In contrast, SoFi has a much simpler and more lightweight setup, with a single camera, a motor, and the same lithium polymer battery that is found in consumer smartphones."

The robot is capable of close observations and interactions with marine life and appears to not be disturbing China rubber O ring to real fish," researchers said.During test dives in the Rainbow Reef in Fiji, SoFi swam at depths of more than 50 feet for up to 40 minutes at once, nimbly handling currents and taking high-resolution photos and videos using a fisheye lens.By changing its flow patterns, the hydraulic system enables different tail manoeuvres that result in a range of swimming speeds, with an average speed of about half a body length per second..Scientists have unveiled "SoFi," a soft robotic fish that can independently swim alongside real fish in the ocean.

These alternating actions create a side-to-side motion that mimics the movement of a real fish."To our knowledge, this is the first robotic fish that can swim untethered in three dimensions for extended periods of time," said Robert Katzschmann from Massachusetts Institute of Technology (MIT) in the US."A robot like this can help explore the reef more closely than current robots, both because it can get closer more safely for the reef and because it can be better accepted by the marine species," said Cecilia Laschi, a professor at the SantAnna School of Advanced Studies in Pisa, Italy.Existing autonomous underwater vehicles (AUVs) have traditionally been tethered to boats or powered by bulky and expensive propellers.

The Ducati bike displays characteristics of an aggressive streetfighter but also retains the traits of conventional cruiser machines. Other advanced features of the bike include Ducati Safety Pack (comprising of Bosch cornering ABS and DTC), cruise control, Bluetooth connectivity, backlit handlebar switches and much more. Launched in two trims – XDiavel and XDiavel S – the former is priced at Rs 15.Powering the new Ducati XDiavel is a 1,262cc Testastretta L-twin with DVT (Ducati Variable Timing) that comes mated to a 6-speed gearbox using a slipper and self-servo wet multiplate clutch.Ducati India seems to be on an offensive.

It launched the Multistrada 1200 Enduro recently and has now added XDiavel trims to its India portfolio.87 lakh while the latter comes with a tag of Rs 18. China rubber V ring Manufacturers Looking at the pricing and the engine capacity, the XDiavel will rival the Harley-Davidson Dyna and Softail range along with the Indian Scout in the Indian market.com. The motor produces 156PS of power at 9,500rpm and a peak torque of 129Nm at just 5,000rpm, which is not exactly what a typical cruiser delivers, though it is close enough.

The bike comes packed with 'Ducati Power Launch,' which is an advanced launch control system that makes it immensely quick off the line. The assembly also gets hydraulic control for smooth shifting and lesser effort.The long, low and muscular Ducati XDiavel is a meeting of Italian experience and cruising culture which is called by the company as a true "Technocruiser.Source: BikeDekho." Moreover, the company is also providing official accessories for the bike, so you can customise it according to your taste. First showcased at the 2015 EICMA motorcycle show in Milan, it bagged the title of the most beautiful bike at the show at the same event.
