Robot for collecting table tennis balls

1. A robot for collecting table tennis balls on ground comprising:

a body for receiving the collected table tennis balls therein;

a rotor means rotatably mounted at a front of the body for picking up the table tennis balls into the body;

a driving module mounted on the body, the driving module driving the body to travel on the ground and simultaneously driving the rotor means to rotate; and

a control device controlling the driving module to drive the body to travel on the ground.

2. The robot as described in claim 1 , wherein the driving module comprises two motors mounted on two lateral and rear portions of the body, two driving wheels connecting with the motors respectively, and two driven wheels mounted on the two lateral and front portions of the body.

3. The robot as described in claim 2 , further comprising two gear sets, the driven wheels driving the rotor means to rotate via the gear sets.

4. The robot as described in claim 3 , wherein each of the gears set comprises a ratchet mounted on the driven wheel, a driven gear mounted on the rotor means, and an intermediate gear engaging with the ratchet and the driven gear.

5. The robot as described in claim 4 , wherein the rotor means comprises two brackets mounted on the front of the body, the intermediate gears pivotally mounted on the brackets.

6. The robot as described in claim 5 , wherein the rotor means comprises a shaft having two ends engaged in the brackets and three blades extending radially from an outside surface of the shaft.

7. The robot as described in claim 6 , wherein the rotor has a lip extending frontward and downwardly from the body, the blades of the rotor means cooperating with the lip to pick up the table tennis balls.

8. The robot as described in claim 1 , wherein the body comprises a bottom plate and three baffle walls extending from the bottom plate, and the bottom plate and the baffle walls form a box for receiving therein the collected table tennis balls.

9. The robot as described in claim 1 , further comprising a detection apparatus mounted on the body for avoiding a collision of the robot with an object on the ground.

10. The robot as described in claim 1 , further comprising a power supply mounted on the body for supplying electrical current to the driving module and the control device.

11. A robot for collecting table tennis balls on ground comprising:

a body for storing the table tennis balls;

a rotor means rotatably mounted at front of the body, the rotor means comprising a shaft rotatably mounted in respect to the body and three blades extending radially from an outside surface of the shaft, the blades being adapted for picking up the table tennis balls and pushing the table tennis balls into the body;

a driving module driving the body to travel and driving the rotor means to rotate; and

a control device controlling the driving module to drive the body to travel on the ground.

12. The robot as described in claim 11 , further comprising a gear set, the driving module driving the rotor means to rotate via the gear set.

13. The robot as described in claim 12 , wherein the gear set comprises a ratchet mounted on a driven wheel of the driving module, a driven gear fixedly mounted on the shaft of the rotor means, and an intermediate gear engaging with the ratchet and the driven gear.

14. The robot as described in claim 11 , further comprises a guiding member having a mounting portion mounted on the body and an arc-shaped lip extending frontward and downwardly from the mounting portion, the blades of the rotor means cooperating with the lip to pick up the table tennis balls.
