Femac 2012 Smart Bird by Festo



Smart Bird is a Robot Bird made by Festo.
The Festo has some robots that mimic some nature animals and the SmartBird is one of them. So if you want to see others go to www.festo.com
The demonstration in this video was made using a celphone by William Basso in the FEMAC 2012 Anhembi — SP — Brazil.
Audio in Português-BR.

Festo – eMotionButterflies (English)



With the bionic butterflies, for the first time Festo combines the ultralight construction of artificial insects with collision-free flying behaviour in a collective. For coordination purposes, the eMotionButterflies make use of a guidance and monitoring system, which could be used in the networked factory of the future.

15 Most EXTREME Vehicles In The World!



Since the invention of the combustion engine, people have been designing unusual contraptions that one can fit in to make them work. From those for military purposes, transport, or just to show what’s possible, there are countless machines that are simply unbelievable. With that in mind we’ve found some of the strangest and most impressive ones that have ever been built, so here the 15 most EXTREME vehicles in the world….

Top 8 New Flying Cars and Air Taxis — Best Personal Aircraft ▶️ 3



Flying cars or air taxis and their business opportunities have recently become a hot topic. In this video, we are going to talk about the new air taxis (flying cars) which were unveiled (from 2019 to 2020). These best personal aircraft include SkyDrive SD-03, Bell Nexus 4EX, CityAirbus, Lift Hexa, Boeing PAV, Seraph, and Heaviside.
SkyDrive SD-03
SkyDrive SD-03 is a Toyota-backed flying car that is billed as the smallest electric VTOL. Equipped with eight rotors that help it fly safely even if there’s a motor failure, this one-seat SkyDrive model can fly for only five to ten minutes at a low speed of several miles per hour. The next version is expected to have a speed of up to 40 mph (60 kph) and an extended flight duration of 30 minutes. The company is currently waiting for approval for flights beyond the test field by the end of 2020, and it expects a two-seat commercial vehicle by 2023.
Lift Hexa
Hexa is an all-electric single-passenger air taxi aimed primarily at tourism and short-distance air travel. With a total empty weight of 432 pounds (196kg), HEXA can carry a 250 lb (113kg) passenger for up to 15 minutes of flight time. LIFT Aircraft is one of fifteen companies which are members of Agility Prime, the United States Air Force initiative to accelerate the commercial market for advanced air mobility vehicles.
Bell Nexus 4EX
Bell Nexus 4EX is a 7,000-pound (3.2 tonnes) air taxi that can hit speeds of up to 150mph (241kmh) and can travel up to 60 miles (97km) while carrying 4 to 5 passengers, plus a pilot.
Boeing PAV
Boeing PAV is a new-generation eVTOL passenger aircraft, or air-taxi designed and developed by Boeing for safe on-demand urban air transportation. Not much is provided about speed and payload weight, but the company says it designed for urban commutes with typical ranges up to 50 miles (80km).
Seraph
Seraph is a 12-rotor British electric flying taxi that can carry passengers and goods weighing up to 550 pounds (250 kilograms) at speeds up to 50 mph (80kmh). The Seraph was built by the company to test new technologies and systems which will be used in the upcoming passenger model, the VA-X1.
ELROY
ELROY is a flying car that is slightly larger than a compact car, but unexpectedly quiet and can fit into most garage spaces. With its high-performance electric motors, this electric-powered vertical take-off and landing vehicle can carry 2 passengers and travel at speeds up to 44mph (70km/h) with a flight time of 20 to 25 minutes.
CityAirbus
CityAirbus is is a fully electric 4850 pounds (2.2-tonne) air taxi manufactured by AirBus. The CityAirbus is autonomously piloted eVTOL and has a cruising speed of roughly 75 mph (120kmh) up to 15 minutes of flight time. Powered by four 140 kW batteries, its 4 sets of counter-rotating ducted propellers can each provide 881 pounds (400 kg) of thrust for a payload of up to 551 pounds (250 kg). The CityAirbus is the successor of Vahana the company’s first air taxi model.
Heaviside
Heaviside is a high-performance electric VTOL vehicle by Kitty Hawk. Kitty Hawk claims the craft’s electric propulsion system, tiny proportions, and aerodynamic shape make it “roughly 100 times quieter than a regular helicopter and it can cover 55 miles (88 kilometers) distance in 15 minutes while using less than half the energy of a car.”

10 AMAZING ROBOTIC ANIMALS



#animalrobots
That's the field dedicated to imitating aspects of nature to better understand, and potentially solve, complex human issues.
It's the reason why so many engineers and researchers are creating robot models of animals.
Robotic animals can help researchers better understand locomotion, evolution, and simply how certain animals accomplish the amazingly unique tasks that they do.
But they can also have tangible applications, from scouting for danger for the marines to aiding in search and rescue missions.

Breakthrough Solid State Battery — 900 Wh/L Samsung [2020]
Samsung research was led by Yong-Gun Lee for an All-Solid-State-Battery (ASSBs). Their goal was to eliminate dendrites formation and increase coulombic efficiency.
To do that they sandwiched layers of Lithium Nickel-Cobalt-Manganese-Oxide (NMC for short) mixed with a Sulfide Solid Electrolytes (SSE, show formula on screen), on top of nanocomposite-layer of Silver-Carbon.
All of this is located in between a foil of Aluminum and Stainless steel as the current collectors.
The idea behind this was to remove lithium foil from the mix and have all lithium atoms part of the NMC and SSE. This approach diminishes the costs of the overall battery manufacturing since handling lithium usually needs an oxygen free environment due to its high reactivity.
This is important for a few reasons, in conventional lithium batteries, the anode comprised of lithium moves freely towards the positive electrode during discharge.
Dendrites are formed during the charging process when lithium moves back to its initial location thanks to the free movement enabled by liquid or gel electrolyte.
This is the main limiting factor of how much energy can be store in these batteries since to control this, the amount of lithium available in the system has to be caped, limiting the energy density.
