We have customized many types of brackets to fit our different parts. Now when it comes to assembling them all together, we find that there are still many shortcomings in our design, such as mismatched sizes and rotating parts being stuck by other brackets. Wait, all kinds of troubles appear one after another. We need to repeatedly remeasure and modify the design to avoid a crash. We also made a lot of compromises to this end. For example, install a set of supporting tires to avoid excessive pressure on the tires. Another example is adjusting the position of the connecting support column inward to leave more turning space, etc.
