Intelligent integral is picked up the tennis robot
Technical field
The present invention relates to a kind of intelligent robot, relate in particular to a kind of Intelligent robot that can help people to pick up tennis.
Background technology
Along with the continuous development of Chinese national economy, we have had increasing tennis court at one's side in recent years, also have increasing people to like to have gone up this motion of tennis, and tennis has entered in the middle of everybody life as a kind of motion of fashion.Therefore but the process of picking up tennis can consume a large amount of muscle power of sportsman and energy, designs such intelligent integral and picks up the tennis robot and have very important significance.
At present existing technical schemes, conclude and mainly be divided into following four types:
The first kind is the ball machine of picking up of hand propelled.Like the patent No. is CN200520059678.3, CN200820208298.5, CN200920151753.7, CN201010128641.7, CN200920090792.0.These type of works need push away car by the people and remove to pick up ball, no intelligent apparatus.
Second type is the ball machine of picking up of electronic control.Like patent No. CN2000910047811.6, CN200910304958.9, CN200820042478.0, CN201010193232.5.These type of works need be controlled to accomplish and pick up ball, no intelligent apparatus by the people.
Pick up the ball car for automatic control for the 3rd type.Like patent No. CN200710190398.X.These type of works can only be picked up a ball at every turn, and efficient is lower.And do not keep away the people and keep away barrier and wait some basic controls, only for being used for experiment, intelligent relatively poor.
The 4th type is based on the robot that uses under the overall control of host computer and place camera.Like patent No. CN200810188136.4, CN200810183233.4.This type of control of works mode is only applicable to large-scale tennis court, and system control mode is comparatively complicated, and cost is higher, and robot must rely on external communication, and changing the place just can't work, and independence is relatively poor.
