Abstract

A wheeled jumping robot includes a body with two wheels, and a board is connected between the two wheels. A driving unit and a jumping unit are respectively connected on two sides of the board. The jumping unit has two rails, and a tubular member is located between the two rails and connected to a threaded rod. A bridge is connected between two rails. Rollers are located between a threaded portion of the threaded rod and a tapered contact face of the bridge. When the threaded rod is rotated, the rollers move toward a pre-set position, the bridge compresses resilient members on the two rails. When the tubular member moves toward the pre-set position, the rollers are separated from the threaded rod due to the tapered contact face, the resilient members bounce back. The wheeled jumping robot includes a processing unit for being communicated with a remote control unit.

Claims

1. A wheeled jumping robot comprising:

a body having a board, a movable unit connected to the body and having driving units and two wheels, the board located between the two wheels, the driving units located on a first side of the board and respectively located at an inside of each of the two wheels;

a jumping unit having two resilient members and a transmission unit, the transmission unit connected with a driving member which drives the transmission unit to compress the resilient members, the transmission unit having two rails, a tubular member located between the two rails and connected to a threaded rod, at least one bridge connected between the tubular member and the two rails, multiple rollers being located between a threaded portion of the threaded rod and a tapered contact face, when the threaded rod is driven by the driving member, the rollers move toward a pre-set position, the at least one bridge compresses the resilient members, when the tubular member moves toward the pre-set position by the driving member, the rollers are separated from the threaded rod due to the tapered contact face, the resilient members bounce back, the resilient members, the transmission unit and the driving member located on a second side of the board, and

a processing unit connected to the movable unit, the driving units, the transmission unit, the driving member and a receiving unit.

2. The wheeled jumping robot as claimed in claim 1, wherein the movable unit has a speed reduction unit which is connected to the processing unit.

3. The wheeled jumping robot as claimed in claim 2, wherein the jumping unit has a speed reduction member which is connected to the processing unit.

4. The wheeled jumping robot as claimed in claim 1, wherein the processing unit is connected to a sensing unit which is adapted to detect a distance between the body and an obstacle, and a height of the obstacle, the sensing unit is an infrared sensing unit.

5. The wheeled jumping robot as claimed in claim 1, wherein the jumping unit has a block which is connected to one end of the driving member and adapted to contact ground.

6. The wheeled jumping robot as claimed in claim 1 further comprising a remote control unit which has a signal transmission device, the signal transmission device transmitting a signal which is received by the receiving unit, the processing unit operates by the signal.

7. The wheeled jumping robot as claimed in claim 6, wherein the processing unit is connected to an image receiving unit which is adapted to transfer captured images to the signal transmission device by the receiving unit, the remote control unit is adapted to display the captured images.

8. The wheeled jumping robot as claimed in claim 1, wherein the body has a cover which is connected to the second side of the board.

9. The wheeled jumping robot as claimed in claim 1, wherein the two wheels are made by plastic and coated with cushion members.
