Safety for Experiments with Batteries
It is recommended to use 1.5V alkaline batteries.
Before using the 1.2V rechargeable battery, please make sure that the battery is fully charged.
(1) Students get the basic materials of this model. (2) A teacher can guide students to assemble the model with the building blocks according to the teaching slide and the student's book and explain the principle and the structure of the model.

(3) Encourage students to write the program of the model first and observe how the model works. A. Make the robot move forward
The green block is a loop. The repeat "value" can control how many times the block program in the loop is executed. If the value entered in this loop is 10, the blue block program will be executed 10 times.

SAMPLE The blue block is to start motor 1 and motor 2.
B. Make the robot stop The blue block is to tell motor 1 and motor 2 to stop because the rotating speed is 0.
C. Program Result The robot moves forward and then stop.
(4)
Ask students to try to make the robot operate or modify the code to see if there are different ways of action. Try to make the ultrasonic robot stop before it touches the object. Program by repeating "until" program blocks.
