Do not choose aliens. I'll teach you how to drive an excavator, as long as you know the function of the joystick. First of all, we must understand the layout of the excavator. There are two poles in front, which are used for driving. When the two poles are pushed forward at the same time, the car will drive forward, and at the same time, the car will drive backward. The greater the push of the pole, the faster the speed, and the smaller the push, the slower the speed. If the degree is small, the car will turn when walking. Then there is a small operating lever on the left and right, which is operated by both hands and used for digging. . . Here comes the main one. . . Right-hand joystick: Push forward, the whole arm will be pressed down (the arm has three moving nodes, which are on the bucket, the middle and the fuselage, and this is the node on the control fuselage, so the whole arm will be pressed down), and pull back, that is, the whole arm will rise, pull left, that is, the bucket will retract (that is, dig), and pull right, that is, the bucket will open outward (that is, pour out the soil). Left-hand operating lever: push forward, rotate the machine body to the right, pull back and rotate the machine body to the left, push the middle arm to the left (generally cooperate with the right bucket to turn over the soil), and push the middle arm back to the right (cooperate with the right bucket to turn over the soil).
