On October 20th, Tesla CEO Elon Musk announced that all Tesla's new cars will be equipped with the "automatic driving function" hardware system - Autopilot 2.0. Musk said that Autopilot 2.0 already has the "level 5 automatic driving ability", that is, fully automated. On October 20th, Tesla China told the First Financial Reporter that Tesla's push-automated driving system in China would abide by Chinese laws. "Do not leave the steering wheel with both hands" is still the fundamental principle that must be adhered to at present.
A Split Hopper Barge (SHB) is a vessel with a large open hold, used to load and transport dredged material. The Barge is loaded by a Cutter Suction Dredger or by a Backhoe Dredger. The barge is self-propelled, and sails to the deposit area, where it unloads the soil. The vessel consists of two halves, and unloading is done by opening, or `splitting`, the two halves, and depositing the soil on the seabed.
A hopper barge is a kind of non-mechanical ship or vessel that cannot move around by itself, unlike some other types of barges, that is designed to carry materials, like rocks, sand, soil and rubbish, for dumping into the ocean, a river or lake for land reclamation.Hopper barges are seen in two distinctive types; raked hopper or box hopper barges. The raked hopper barges move faster than the box hoppers; they are both designed for movement of dry bulky commodities.

Autopilot 2.0 has a fully automated driving level
On October 17, Musk revealed on his Twitter that the mysterious product launch scheduled to be held this week was postponed for two days. But he did not disclose the specific reasons at the time, just saying "it needs more time to improve the details." At that time, some analysts thought that the new product might refer to the repaired new generation of automatic driving system. Others thought that the so-called mysterious new product might be the Model 3 sedan, or even the rumored compact crossover model Y.
The mysterious product that finally unveiled the veil is the "automatic driving function" hardware system - Autopilot 2.0, which includes three major technologies. First of all, the system will contain 8 cameras, covering 360 degrees of visibility, and monitoring the surrounding environment up to 250 meters. Secondly, the vehicle's 12 ultrasonic sensors complete the vision system, detecting and sensing hard and soft objects at twice the distance of the previous generation system. In addition, the enhanced front-end radar provides richer data around the redundant wavelengths, which can travel through heavy rain, fog, dust, and even vehicles in front.
At the same time, the new Tesla vehicles are also equipped with a more powerful in-vehicle computing system. The GPU chip provided by NVidia has 40 times the computing power of the previous generation. It runs Tesla's vision system based on deep neural network and sonar. With radar system software.
“The system provides a world image that the driver can't reach with the eyes, and detects each direction of the vehicle through the band synchronization, which goes far beyond the human senses,†Tesla said on his official website.
For the automatic driving level of this hardware, Musk said that Autopilot 2.0 already has the "level 5 automatic driving ability". According to the Automated Driving Technology Grading Standard of the Society of Automotive Engineers selected by the US Department of Transportation, Level 5 is fully automated, that is, automatically automated under all road and environmental conditions that human drivers can handle. The driving system performs all driving operations autonomously.
"Full automatic driving is definitely the direction of automotive technology development, but the industry has generally believed that the implementation of fully automated driving will wait until 2020." Lai Yanjie, an analyst at Northeast Securities Automotive Electronics, told the First Financial Reporter that Tesla had this It is revealed that before the end of 2017, it will hold a fully self-driving parade from Los Angeles to New York. Then by 2018 Tesla's fully automatic driving is expected to really go to the public, which is two years ahead of the industry's general estimate.
Lai Yanjie said that the current mainstream auto manufacturers in the world are not active in fully autonomous driving, and they still have a conservative attitude, including concerns about the safety and stability of the system. However, Lai Yanjie also said that Tesla's integration of sensors, especially the setting of camera plus millimeter wave radar, is a great innovation highlight for the response to rain and fog.
“Do not leave the steering wheel with your hands†is a principle that must be observed at present.
2016 is a troubled autumn for Tesla. In May 2016, a Tesla S-type sedan had a car accident on the Florida Freeway. It was reported that the vehicle was in an automatic driving mode at the time of the incident. However, the self-driving system suspected that the white truck was not recognized, resulting in the vehicle not being Start the brakes and hit the truck.
In January 2016, Grace Ning crashed into the body in Hebei Province, when he drove a Tesla ModelS. The conclusion of the Cixian Brigade of the Hebei Expressway Traffic Police Detachment after the accident was that the rear white Tesla sedan was in the road cleaning operation vehicle under construction, and did not take any emergency braking and avoidance measures.
With several reports of car accident news, the safety issue of autonomous driving technology has sparked heated discussions. In terms of regulations on autonomous driving, the relevant person in charge of the Ministry of Industry and Information Technology of China said in July that the Ministry of Industry and Information Technology is working with the police to formulate laws and regulations governing the test of self-driving cars, and reminds automakers not to test autonomous vehicles on highways before the regulations are issued. Zhou Wei, chief engineer of the Ministry of Transport, revealed in April that at present, the Ministry of Transport and the Ministry of Industry and Information Technology are cooperating to jointly promote the relevant legislation on autonomous driving.
Tesla China’s relevant person told the First Financial Reporter on October 20 that the auto-driving system announced by Tesla was only a hardware system, and the upgrade of the software system took time. At present, the system on the main car of China Tesla is an automatic assisted driving system. The driver's hands should be placed on the steering wheel, and the whole system only plays the role of assisting driving. But the person also said that compared to other manufacturers including Apple, Google, etc., Tesla's advantage in addition to technology, there are a lot of road data, these are not simulated by other manufacturers. Even in the event of a car accident, Tesla will not stop exploring the autopilot technology in the face of public opinion pressure. However, he also stressed that Tesla's push-automated driving system in China will certainly abide by Chinese laws. At this stage, the owner of the car "do not leave the steering wheel with both hands" is a principle that must be observed. 
Split barges serve the same purpose, but instead of a door in the hull's bottom, the hull of the whole barge splits longitudinally between the end bulkheads. The vessel consists of two major parts (port and starboard halves), both are mostly symmetrical in design. Both parts of the vessel are hinged at the deck and operated by hydraulic cylinders. When the vessel splits the load is dumped rapidly, which means the barge has to be very stable in order not to capsize or otherwise get damaged.
