CONSTITUTION: A driving device comprises a main body(100), a work unit(200), and driving modules(300). The work unit is coupled to one side of the main body to rotate more than 2 degrees of freedom against the main body. The driving modules are coupled to both sides of the main body to rotate with one or more degrees of freedom against the main body. Each driving module comprises a support body and auxiliary wheels. The support body is coupled to the main body. The auxiliary wheels are rotationally installed in the support body. |
