Lesson 8 Domino building

CONTENTS I. Introduction of subject II. Explanation of knowledge points CONTENTS III. Skills competition IV. Classroom summary

I. Introduction of subject

Domino 1 1

It is time to operate by yourself!

2 Come to build the blocks Build a line-styled Domino structure with 15 Dominoes, and keep the width of a Domino (2.5cm) between the Domino center points. 2.5cm

II. Explanation of knowledge points

1 1 Program flow chart The gripper opens Move to the position to store Dominoes The gripper closes to pick up Domino Move the target position to building the blocks The gripper opens to place Dominoes Complete the building of the blocks, and the manipulator lifts Cycle for the specified times 1 1

2 The gripper picks up a Domino In what way the manipulator picks up Dominoes? 2

1 3 Domino layout mode Maximum movement range of Y axis What is the best location for Domino and the manipulator? Maximum movement range of Y axis 1 3

Law of storage points What is the distance to be moved by the manipulator between two Domino storages? 4 2.5cm Change the fixed coordinate value of Y axis

1 5 Naming of a variable Variable of Y coordinate Variable of pick-up times: i

6 Variable assignment Initial value of pick-up times Variable assignment of Y coordinate

1 7 Cycle of the specified step For 15 Dominoes, pick up and store them repeatedly for 14 times, and the Y axis coordinate is related to the repeating times. 1 7

Cycle the pick-up according to the step 8

1 9 Point-to-point movement Gate-type movement MOVL: The path from point A to point B is a straight line.

III. Skills competition

It is time to operate by yourself!

I control my manipulator Operation purpose: Blockly programming advancement Operation task: the manipulator builds Dominoes automatically

Program example

I control my manipulator (advanced) Operation purpose: Blockly programming advancement Operation task: the manipulator builds the complicated Dominoes automatically

IV. Classroom summary

Summary What have we learned in this lesson? - Definition and assignment of variable - Mathematical operation - Cycle structure of the specified step - Achieve gate-type movement through point-to-point module

After-class thinking - What kind of kit can be used to build Dominoes in addition to the gripper? - What are the advantages and disadvantages compared with the gripper kit?
