An assembled robot toy includes a power supply module, a gear box, a rod component, a head part and an assembly component. The head part and the assembly component are detachably arranged on the gear box. The gear box includes a motor, a first gear, and a transmission gear set. The power supply module is a solar panel. The power supply module is electrically connected to the motor. The first gear is arranged on a rotating shaft of the motor. The transmission gear set includes a second gear that meshes with the first gear. A total number of teeth of the first gear is less than that of the second gear. The rod component is connected to the second gear, and the assembly component is connected to the transmission gear set and/or the rod component. The rod component and the transmission gear set are used for power outputs.

Provided herein are devices for propelling string through the air. The device includes two wheels, a motor, a head, a handle, a detachable cover, and at least one UV light source. At least one of the two wheels can be operable to be driven by the motor. The two wheels can be rotatably mounted to the head and form a gap operable to receive a portion of the looped string. The wheels then propel the string from the device.
