The Dragon Knight Kit contains at least 50 mechanical and electronic components. It is modeled after the Dragon Knights from Star Wars. A total of 8 intelligent servos are used, and a series of actions can be performed with the handle controller, and various modes can be selected, such as obstacle avoidance mode, remote control mode. Can also control the Dragon Knight to do push-ups. During Dragon Knight movement, the lamp bar above the Dragon Knight board can display different colors according to different movements. The principle of the dragon knight is that the four legs swing and crawl forward at different times. Each time the foot is raised, only one foot is raised. The remaining three legs are used as a support. The raised foot turns forward and then lowers again. The other foot is lifted and moved forward again.
