What do you think is the most basic function of a manipulator? Interaction What do you think is the most basic function of a manipulator? If we want to handle objects with a manipulator, what kit can we add to it?

II. Wonderful sucker

Wonderful application of sucker

1 1 Double click the icon to activate the software Control manipulator: understanding of the software 1 1 Double click the icon to activate the software

(the angle between boom and jib is about 45°） Connect the manipulator 2. Power on (the angle between boom and jib is about 45°） 2 1. Connect the manipulator to the computer

2 Connect the manipulator 3. Connect the manipulator to the software Attention:

1 3 Connect the air pump kit Sucker kit Sucker kit Air pump box 2. GP3 1. Connected the sucker to the manipulator through the butterfly nut 2. Connect the sucker GP3 interface to GP3 interface of the manipulator 2、GP3 1. Butterfly nut Air pump box: The device used to remove air from a closed space or add air from a closed space Air pipe 2. GP1 1. SW1 1. Air pump box SW1 is connected to the host box interface SW1 2. Air pump box GP1 is connected to the host box interface GP1 3. Air pipe is connected to the joint on the sucker 2、GP1 1、 SW1 1 Air pump box Sucker kit 3 Sucker kit Grip the product with a rough surface with the sucker

Succeeded! Connect the air pump kit 1 3

4 Mouse follow-up mode Control the manipulator 1 – mouse follow-up Attention: The manipulator can move in the sector area only Mouse follow-up mode Control switch Moving speed

It is time to operate by yourself!

4 ③ ④ ② ① ① Joint 1（J1） ② Joint 2 （J2） ③ Joint 3 （J3） ④ Joint 4 （J4） Control the manipulator 2- single axis 4 The anticlockwise is the positive direction by default ① Joint 1（J1） ② Joint 2 （J2） ③ Joint 3 （J3） ④ Joint 4 （J4） ① ② ③ ④ The dashed line refers to the zero position of the corresponding joint

It is time to operate by yourself!

Initial position Target position Handle the building blocks (single axis mode) Task rules: The length of time is 4min, and based on the by-group method, the members of the group take turns to use the single axis control mode to operate the manipulator, and move the building blocks from the initial position to the corresponding target position. Area A Area B Dobot manipulator

4 Control the manipulator 3 - coordinates The origin of the coordinate : the intersection of the three axes of the motor s of boom, jib and base 4 Z axis: Vertical, upward End center X axis: Vertical to the fixed base, forward Coordinate origin (0.0.0) Y axis: Vertical to the fixed base, leftward R: The posture of end actuator center point relative to the coordinate origin

It is time to operate by yourself!

Handle the building blocks (linear mode) Target position Initial position Handle the building blocks (linear mode) Task rules: The length of time is 4min, and based on the by-group method, the members of the group take turns to use the linear mode to operate the manipulator, and move the building blocks from the initial position to the corresponding target position. Area A Area B Dobot manipulator

III. Skills competition

Relay handling of the building blocks Initial position Target position Relay handling of the building blocks Task rules: Based on the by-group method, the members of the group take turns to use the various mouse control modes to operate the manipulator, and move the building blocks from the initial position to the corresponding target position. Assessment method: The group that completes the game at faster speed and more accurately will get higher score. Area A Area B Dobot manipulator

Game score table Round Control mode Group 1 Group 2 Group 3 Group 4 Single axis mode 2 Linear mode 3 Mouse control mode 4 Custom 5 Total points

IV. Classroom summary

After-class thinking - What are the advantages and disadvantages of three control modes of the manipulator? - Is it possible to increase the range of motion of the manipulator in any way? - Is there any room for improvement of the manipulator?
