After 10, 2020, after more than four months of completing the concept proposal, marketing publicity, re-design and small-scale trial production of the white dolphin unmanned sweeper, the second project was finally ushered in. The strategy was still the same. The first step was to do the concept design. The boss WeChat and telephone bombing called me to the company's office to prepare. The atmosphere, like a battle meeting, was like a conspiracy before the war. After explaining it again, the design began.

Time-critical concept proposal did not have much time, and I called the appearance of the product designed by Ulm student in my mind, Ulm student Alexander. The German ICE high-speed rail designed by Neumester and a derivative of this series of models, a certain model of China High-speed Rail Harmony, are used for style extraction, and some related content of visual dynamics theory is combined for visual comfort detection.

The design was completed after 2 days of design. (There was no stp model inside, but I was afraid that I could not pack it, so I put the digital model of the previous product into it as the internal hardware, which made my heart more stable.)

Change the color to the green of the company representative.

The hydraulic cylinder should have been used for lifting, but considering that it is now a conceptual design, if it is not enough time to establish the digital model, it can only be replaced by the previous electric push rod digital model.

On both sides are garbage cans for garbage dumping, and the manipulator in the middle can pour the garbage cans from the community into the garbage cans on both sides. Lidar direction is not used on the unmanned route, and the pure visual unmanned route is selected, which is the design direction of Tesla's unmanned driving. The visual camera is on the flanging of the most sides of the trash can.

After the design was completed, the boss was not satisfied, but I didn't know where the problem occurred. After I returned to my post, I looked at the simulated motion interference and found that the garbage could not be thrown away at all. Finally, I drew a hand drawing by hand drawing and redesigned it. The garbage can material uses glass fiber (glass fiber has low density and high strength, so it has high specific strength, it can maintain its strength under the condition of reduced weight, and it saves electricity when the vehicle is driving.)
Later, the concept proposal of this paragraph was not successful, and the start-up funds for the project were not obtained. The design work without funds also fell through. After that, there was almost no design work from November to March-April 2021 of the following year. After that, I took part in the assembly line work. Originally, the main work was the laser cutting operator. Later, the operator of the unmanned robot resigned. I also worked in the programming and welding of the unmanned robot operator. However, there was always a shortage of people on the production line and I also worked as a sheet metal bending, assembly screwdriver, lift truck porter. It is from this beginning that the trough of life begins to come.
