The utility model relates to the technical field of household appliances, and discloses a projection
robot, which comprises a spherical shell, the shell is provided with a first opening communicated with an inner cavity, and the bottom of the shell is provided with a driving wheel; the projection
assembly is located in the inner cavity; the driving
assembly comprises a driven shaft mechanism, and the driven shaft mechanism is arranged on the shell and connected to one side of the projection
assembly; the motor support is arranged on the shell and located on the side, away from the driven shaft mechanism, of the projection assembly. The motor is arranged on the motor support and connected to the side, away from the driven shaft mechanism, of the projection assembly, the rotating axis of a driving shaft of the motor coincides with the rotating axis of the driven shaft mechanism, and the rotating axis roughly coincides with the spherical horizontal
central plane; the inner shell is located in the inner cavity, and the inner shell is fixed to one end of the projection assembly so that the inner shell can rotate in a pitching mode along with the projection assembly. According to the projection
robot, the adjustable range of the projection orientation direction of the projection assembly is large.
