How to Make a Remote Controlled Spider Robot!!!



In this video I show you how to make a remote controlled spider robot.
Clarification… The introduction of the video is stop motion animation, it was only done to visually enrich the content and to exemplify how the idea was born without using a real spider. I do not intend that you believe that the final result of the product is the same.
Also keep in mind that remote control does not always mean that it is Radio Control, since you can control something remotely even when using a physical connection.
Keep in mind:
The content shown in this video is experimental, everything was done during the recording, if you plan to recreate what is shown here, be careful when using the tools and keep in mind that you must have basic knowledge of electronics and basic tools.
Read the following recommendations if you plan to recreate it.
-Don't make the same size shown here, in spite of having included other 2 motors, a 9-volt battery was used at the end to move and the motors were burned after a while of operation, the problem is solved if it does smaller maybe half or less.
— Get a battery holder for 4 units, it's better and cheaper than doing it manually.
-The engines have to be all similar.

Solar Panels on a Tesla



Electric cars and solar panels seem like a match made in heaven: free, clean power as long as the sun shines. A self reliant, solar car that’s not dependent on the power grid could recharge sustainably from anywhere you dare to venture.
So, have you ever wondered about bolting solar panels on your Tesla? And why don’t all electric cars come equipped with solar panels for a sleek charge-on-the-go solution? In fact, with improving solar technology and clever ground-up engineering, a few self-charging solar cars are just at the point of coming to market. In this video we’ll delve into the practicalities of solar power for vehicles and have a look at some of the early adopters of this emerging technology.
In 2017, Elon Musk suggested that Tesla would offer optional solar tiles on the roof of the model 3, but later retracted the statement. This was Elon Musk’s idea in 2017 – that car roofs are small and inefficiently angled platforms for viable solar installations, and charging from a home solar installation made more sense. You could even charge at night on stored solar and cheaper off peak electricity. However, Elon might have changed his mind, confirming that the Cybertruck will offer a solar roof option on the truck’s bed.
To understand if a solar car could really work, we need to find out how much solar energy the surface of a car can capture, and how much range that energy will provide under realistic driving conditions.
So let’s take a sedan the size of a Tesla Model S, almost 5 m long and 2 m wide, and put a totally impractical, hypothetical array of solar cells covering the whole plan-view rectangular area of 10 square meters.
When it comes down to it, solar vehicles are all about efficiency. It’s a matter of energy to weight. A practical solar car would really need to be designed from the ground up with reduced weight and low aerodynamic drag, to create a vehicle with more favorable energy density. For as far as electric cars have come in the last decade, the energy density of gasoline is still far greater than lithium ion batteries.
Teams gather each year in Australia to race pure solar cars across the continent from Darwin to Adelaide under the scorching desert sun for the World Solar Challenge. Consistent winners of this class have been the evolving Stella series from the University of Eindhoven, the team from which Lightyear sprang in 2016. Lightyear one reevaluated every component of the car and used lighter materials like aluminum and carbon fiber, to build a lighter vehicle with the best aerodynamic coefficient of any car on the market. Four independently driven in-wheel motors also lower the cars weight, and improve powertrain efficiency.
Sono Motors on the other hand, are starting with a more affordable $29,000 compact solar car designed for urban use. In designing the Scion prototype. Sono’s proudest new technology integrates solar cells into polymer body panels to replace conventional painted metal bodywork.
Toyota has experimented with a demonstration Prius with high efficiency thin-film triple junction cells made by Sharp, and Hanergy Solar, a Chinese manufacturer of thin film panels, have also demonstrated prototype cars with panels that can harvest 8-10 kWh per day and supplied such panels to Aston Martin for their GTE racing car.
Most solar panels rely on cells made from semiconducting silicon crystals, which convert sunlight to electricity at around 15%-19%, but new technologies are in the works to create higher efficiency solar cells utilizing new materials. As the future unfolds, and more cutting edge solar technologies come to market, we can see self charging solar electric vehicles become more and more practical, as cells get more and more efficient. A future cell technology with efficiencies above 50% would be a game changer, and probably make solar cars ubiquitous.
Heavy batteries are a limiting factor in the feasibility of solar cars. A breakthrough battery with more favorable energy to weight characteristics would revolutionize electric transportation, and make solar cars far more realistic.
Promising new technologies that utilize materials like graphene, solid polymers, and ceramics are currently in research and development, and are poised to create the next generation of powerful batteries with higher energy density, greater service life, faster charging, improved safety, and potentially even lower costs.
So should you mount a solar panel on your Tesla to make it a solar tesla? Watch the video to find out.

Beast Electric 4X4: Off Road Vehicle



This beast is called the EZRaider HD4, it’s a personal all terrain 4X4 vehicle and don’t you dare call it a scooter. Its creators claim its the most capable off-road platform in the world, and the US Armed forces concur, because the $19,2000 EZ Raider just passed an operational evaluation with the special forces, and they’re ordering more units.
Mud or sand, rocky peaks or thick backcountry, the all electric, all wheel drive EZRaider provides a unique combination of power, agility, and usability. I recently got the opportunity to go on some clandestine missions myself around my neighborhood, and I can tell you, besides its function as a utility vehicle, it’s an absolute blast to ride.
www.ezraiderus.com/
Powered by a 60V — 3000 W/h lithium ion battery pack with an advanced BMS, and equipped with a 4 wheel drive system for extreme off road adventures.
The EZRaider HD4 has four independent 1,200 Watt brushless Hub-motors, and it’s 4 matching dedicated Sine-wave Controllers can reach peak outputs up to 18,000W it’s more than an electric scooter or off-road scooter. Outfitted with top quality components like chromoly driveshafts and Japanese precision bearings, the powertrain provides instantaneous power and high energy efficiency.
Engineered for stability across diverse terrain, the EZRaider features a patented 6 axes, 360 degree, Floating Long Travel Suspension that can flatten all terrain. In combination with the 4 wheel drive system, and beefy 22 X 7-10 tires, the 10 inches of ground clearance allow an experienced rider to crawl over remarkably challenging surfaces.
Each wheel is equipped with dual piston caliber Hydraulic disc brakes, and you can really feel the strong slowing pull of the regenerative breaking as you let off the accelerator, which takes a bit of getting used to.
Both the US Armed Forces, and the Israeli defense forces are currently performing an operational military evaluation of the EZRaider HD4, and after a series of successful tests, they’re in the process of ordering more for different fighting units as a new military vehicle. In combination with the tactical military Tesla cyber truck we envisioned in a previous video, this could be an unstoppable electric combination.
When it comes to useful working applications for the HD4, the possibilities are endless. Along the same vein as its military and defense uses, the EZRaider also makes a fine patrol vehicle for police, border patrol, or even campus security. In fact the Israeli police are already using the EZ RAIDER in its border units. One thing’s for certain, as a patrol vehicle, it’s not only more capable than a segway.
For more agrarian purposes, the EZRaider makes an excellent ranch vehicle for chasing down cows, hunting, or just simple transportation over rough terrain.
As electric power is transforming the automotive world, with EV adoption rates growing at about 60% each year, technological advancements in motor efficiency and improvements in battery storage technology are giving rise to a new generation of quiet, sustainable electric vehicles.
With its unique new form factor, and powerfully efficient electric powertrain the EZRaider is an exciting new entrant in the off road category, and we look forward to seeing what other new vehicles will emerge in our electric future.
PS who needs the Tesla Cyberquad electric ATV when you have this?

Lithium-ion battery, How does it work?



A portable power supply has become the lifeline of the modern technological world, especially the lithium-ion battery. Imagine a world where all cars are driven by induction motors and not internal combustion engines. Induction motors are far superior to IC engines in almost all engineering aspects, as well as being more robust and cheaper. Another huge disadvantage of IC engines is that they only produce usable torque in a narrow band of engine RPM. Considering all of these factors, induction motors are definitely the perfect choice for an automobile. However, the power supply for an induction motor is the real bottleneck in achieving a major induction motor revolution in the automobile industry. Let’s explore how Tesla, with the help of lithium-ion cells, solved this issue and why lithium-ion cells are going to become even better in the future.

The truth about graphene — what's the hold up?



Go to brilliant.org/Undecided you can sign up for free. And also, the first 200 people will get 20% off their annual premium membership. The truth about graphene. Ever since it was first discovered in 2004, graphene has been hailed as one of the most important breakthroughs in materials since the plastics revolution more than a century ago. The early predictions were that graphene would almost immediately enable the kinds of products and technologies that we're used to seeing in sci-fi movies. Cut to more than a decade and a half later and that still hasn't happened. Not even close. With opinions split between people overhyping graphene or calling it a massive disappointment, it's time we got to the truth of what is really happening with this so-called 'wonder material'.

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.
