You will need two 370 geared DC motors with a shaft diameter of 7 mm and a speed that you can choose. The battery voltage should be between 7.4 and 12 V. For the shock-absorbing component, you can replace it with tension springs for better elasticity. You must also obtain the tank track plates shown in the diagram—make sure to buy the exact type depicted in the photo, as other versions may not be compatible. Additional required components are listed in the materials checklist. This is an original design; feel free to follow the Bilibili UP master “Meng Ye Gu Shou” for more information on track designs and other related content.
