Picar-X Lesson 1: Assemble 01

Basic Teaching Information

Suitable School Age

8-10 years old.

Duration

90 minutes

Teaching Objectives

1. Introduce parts and structures. Let students understand the sensor module, what PiCar can do and how to play.

2. Through practical operation, let students master the use method of installation tools (screw, nut, screwdriver, socket wrench).

3. Assemble PiCar ~ step 11 on PPT: fit FFC cable.

Important and Difficult Points of Teaching

Teaching Key Points

Through the explanation, students can know each device and its basic function.

Let students use tools correctly through the demonstration.

Teaching Difficult Points

When students assemble FFC cables, the assistance from a teacher is needed.

Teaching Form

PPT presentation, cooperative group learning.

Teaching Media

Teaching Grouping and Teaching Aid

Teaching Group

 Work in groups of one person.

Teaching Aid

PiCar kit, pen, programming growth manual.

Duration

1. Course Introduction

Teacher’s self-Introduction.(The teacher can make his own modifications)

 Establish classroom rules. (Each teacher makes his own changes according to his own rules)

15minutes

2. Material Learning

1. Today we're going to start the first part of our class -- assemble our own smart car, PiCar. Three, two, one, open the boxes on your desks.

2. Next we get to know the main components:

The top layer of white structure makes up the shell of the car.

Let’s try.(This step is intended to give students an overall impression of the body structure during the formal assembly. If condition allows,  the teacher can prepare a sample car for reference. The teacher can point out where these parts are assembled on the car. This step takes about five minutes.)

3.Know modules and the main control board:

The second layer are sensors and the main control board of PiCar. Does anybody know what they are? (ultrasonic sensor grayscale module, camera module   Raspberry Pi, robot extension plate. If the students have a good learning foundation, the teacher continues to ask questions about where these modules are to be put and what they are used for. This step takes five minutes.)

Learn about servo and motor.

The second and third layers are assembled with servos, motors and wheels respectively. Ask students the difference between servo and motor, and guide students to answer that motor can make the car go forward, and the servo can adjust the steering of the front wheel and the camera.

Guide the students to say where the parts will be put. Students with good foundation can be further guided to describe the similarities and differences between the two.

15 minutes

3、 Start assembly

1. Let the students follow the PPT to complete the assembly steps.

2. If necessary, demonstrate how to use screwdrivers, screws and nuts.

3. On average, each step is limited to about five minutes

4. Ideally, the assembly of these three servos should be completed in this lecture (Step 11 on the PPT).

40-50 minutes

4、Material Arrangement

 

1.Ask students to put unused materials back in the box to avoid losing.

2.Help less advanced students to catch up.

10-20 minutes
