Remote control cars are fun, but self-driving robot cars are even more fun. In this tutorial, we'll build a four-wheeled robot that can drive around and avoid obstacles. I purchased this complete 4WD kit from AliExpress, but you can easily buy most of these components at an electronics store and assemble them yourself.

I recommend reading through all the instructions before starting, as this will clarify some things that may be confusing on the first run-through. Because of the length of the instructions, this can also look like a very long, advanced project, but it's actually pretty simple. You don't have to be intimidated – this is a beginner's project that you can get satisfying results with and build on as you learn more. Don't like this robot?

Daytime running lights bring neither advantages nor disadvantages

New vehicle models may only be registered throughout Europe if they are equipped with so-called daytime running lights. The benefits of additional lighting are questionable, however, according to a study by the German Insurers Accident Research (UDV) in Berlin. Together with the Technical University of Berlin and the research institute Human-Factors-Consult, the scientists investigated in a two-and-a-half-year project what effects driving with lights on during the day has on road safety, especially for weaker road users such as pedestrians, cyclists and motorcyclists. Result: practically none. At least it's comforting to know that daytime running lights don't hurt either.

For a long time it was suspected that motorcyclists, for example, in the "More" and would therefore be more likely to be involved in risky situations or accidents. In Austria, for example, this assumption led to the abolition of the obligation to drive with lights on during the day.

After extensive series of tests in the light channel, in a driving simulator and in road traffic, the UDV researchers concluded that daytime running lights do not "bind" drivers' eyes. It is also not true that weaker road users are seen later or not at all. Motorcyclists, too, do not disappear in the midst of illuminated cars in such a way that they are no longer noticeable to oncoming traffic, for example. In cloudy weather or rain, the eye stays on the illuminated car a little longer. However, this is not at the expense of other road users.

Since when is there car tuning?.

The Autotuning

What is Autotuning? The car tuning is also often called vehicle tuning. Serves to change on the vehicle respectively. Car to get a higher performance. You can do the tuning on all kinds of vehicles such as motorcycles, trucks and everything else that drives. Basically, car tuning means nothing more than fine tuning the car parts, such as those of the engine, the body or even the chassis. Often additional car parts are installed to have a more powerful car, but now and then things like for example the cylinder or the like are drilled out. But of course, car tuning also includes changing the appearance, which is often colloquially called aufmotzen.

Where can you have a car tuning done?

There are special companies that do the car tuning for extra charge. These companies resp. Workshops are usually called vehicle tuners. There, however, often not only small things are changed on the car, but entire engines are replaced. Because the customer does not always have the wish that his car should become faster, but from time to time he would also like to puff up simply only the optics of the car interior a little bit. This task is mostly done by so-called customizers, who are especially responsible for such tasks.

Since when there is the car tuning?

The whole tuning story actually started in the 50s, when the first self-proclaimed tuners pimped some VW Beetles to make them faster. Shortly thereafter, various aids, such as spoilers, shock absorbers or brand-new brake systems came on the market. By these things the Tuning went into the history, because starting from the 70's the Autotunen was not to be imagined at all away. Everything that was drivable was machined to increase performance, whatever it may cost. Spare parts made of plastic were a hoot. The original skirts were removed. Replaced by the new body parts. Nothing was impossible. There was no limit to the imagination. But as quickly as this trend came, it also went again. At the end of the 90s, the car tuning boom slowly subsided.

Study 'share' multi

Free-floating carsharing is a form of temporary car use in which vehicles are available for spontaneous use in public street space and can be parked again at any public parking lot after the trip. This form of car sharing has been around for around ten years, while station-based car sharing continues to exist.

In the "share" project, the Öko-Institut and ISOE – Institute for Social-Ecological Research investigated several research questions using the example of free-floating car sharing by car2go:

Which population groups use free-floating car sharing?? What are attractive, what are inhibiting factors of usage? How do users accept. Users of electric vehicles in the vehicle pool? What are the effects of use on car ownership and are there significant changes in travel behavior as a result of free-floating carsharing, and thus also on transport-related greenhouse gas emissions??

Supporting the driver helpfully in everyday life

Under the hood the Crossover uses basically the same technology as the Fiesta. But compared to its gene donor, the Puma is a good 14 centimeters longer. In addition, the wheelbase has been stretched to 2.59 meters and the track widened by a few millimeters. For this reason, the Puma also offers a bit more space inside. When it comes to the engine range, Ford also uses the Fiesta, but with one small difference. While the 120-hp four-cylinder diesel has been removed from the Fiesta lineup, it is still on the price lists for the Puma. In the gasoline models, on the other hand, the Cologne-based company relies on downsized three-cylinder engines that draw their power from just one liter of displacement, just as it does with the Fiesta. The power range for the Puma is 95, 125 and 155 hp, with the two more powerful variants being mild hybrids. The portfolio is topped by the particularly dynamic Puma ST, which squeezes a hefty 200 hp out of a 1.5-liter three-cylinder gasoline engine.

Our tested Puma, on the other hand, is a mild hybrid with a 48-volt. He brings it to 155 hp. Starts accordingly at 25.600 euros.600 euros. The Puma can't run purely on electricity because it's a hybrid of the mild variety. However, the combustion engine receives active support from a starter-generator during acceleration. In addition, the energy recovered in the partial load range or during braking is stored in a lithium-ion battery and returned to the system as needed. Saving fuel.

Standard consumption only just exceeded

The excitement was great when, on the morning of our third day in Havana, we let the front door fall into the lock behind us and were now sitting on the street with our large backpacks. Would our arranged shared cab come? We had already heard that Cuban punctuality should not be emphasized so much. But everything worked well. After only half an hour of waiting, a car finally stopped on the opposite side of the street. The driver waved at us. We loaded the luggage into the trunk. Three of us took seats on the front bench of the car. Our driver's name was Julian, he spoke almost no English, but he was particularly talkative! From his words and the free back seat, we combined that we now have to pick up other passengers first. So we got again a free round trip through the old town. This also took a little longer, because Julian did not know exactly where the other casa was located. But no problem at all – we just asked all the people at the roadside until the right house was found. After we had collected two more Swiss, we went now to the west of Cuba: To Viñales! Soon we entered the autopista, the "highway" of Cuba, a wide asphalt strip that could be used by any vehicle and animal. Beside the oldtimers there were cattle trucks, which were converted to buses, mopeds and even bicycles. But also horse carriages and ox carts used the hard shoulder next to some broken down vehicles. An open hood – not a rare picture in Cuba.



Black, green or red the right license plate for everyone

Every vehicle must have one on the road, but there are many more than just the "normal" one black license plates. The following is a brief overview of German license plate types.

The best-known license plate is, of course, the one with the black letters. It consists of a distinguishing sign for the administrative district (place) and a recognition number. Only eight digits are allowed on it.

E license plates for electric vehicles and H license plates for classic cars

There are two variants of the black license plates: Since September 2015, owners of electric vehicles can have a license plate with the letter "E" on it Apply behind the distinguishing number. Eligible electric cars include battery-only electric vehicles, externally chargeable hybrid electric vehicles (plug-in) and fuel cell vehicles.

The connectivity experience is seamless and intuitive

The Nissan Micra enters the 2018 model year with expanded equipment and new prices: the chic hatchback now comes with an improved Nissan Connect infotainment system, engines converted to Euro 6c and other product updates. Despite the upgrades, the price list in the future starts at 11.990 euros. That corresponds to one around 1.000 euros lower entry-level price.

The connectivity experience is seamless and intuitive. The smartphone is easily integrated into the vehicle system via Apple CarPlay® or Android Auto®. Together with the extended functions of the new Nissan Connect, the full power of the mobile Internet can be used.

Even though the new Nissan Connect with seven-inch screen hardly differs visually from the previous system, the changes are profound. Nissan has reduced the number of buttons, but most importantly, the new capacitive display for multi-touch operation provides an entirely new user experience. The start screen of Nissan Connect can now be personalized, frequently used functions can be stored on the display and thus accessed directly. Alternatively, it can be operated via integrated voice control, which is activated at the touch of a button on the steering wheel.

Škoda auto cuts production by the end of 2022

October 2021 to significantly reduce production at the three Czech plants by the end of 2021 and also does not rule out a partial shutdown. This was reported by the Czech news agency ČTK with reference to the person responsible for corporate communications Tomáš Kotera. As a reason, the latter cited the lack of chips needed for the onboard electronics. The company now wants to focus on completing the large number of unfinished cars. For months now, the number of cars in stock and waiting for parts to complete them has been hovering between 30.000 and 50.000.

Forecast revised downward

Volkswagen subsidiary Škoda Auto is the leading company in the country, accounting for two-thirds of Czech car production. Of the other two automakers, ČTK says Hyundai plans to maintain production. Toyota continues to work with restrictions. The global shortage of semiconductors and subsequently of electronic parts has impacted the recovery of the automotive industry. Since the summer, there has been an increase in stoppages. These also affect the supplier sector, which represents about half of sales.

As early as August, the extended vacations at car plants had a negative impact on the production index of the Czech industry as a whole. After five very good months, this fell by 1.4 percent in real and calendar-adjusted terms compared with the same month last year and by 3.2 percent in seasonally-adjusted terms compared with the previous month. In the motor vehicle industry (NACE 29), there was a slump of 28.4 percent and 8.6 percent respectively. According to the Czech Statistical Office, incoming orders were also the only industry to decline in August.
