OSOYOO V2.1 Robot car kit Lesson 3: 

Object follow Robot car 

 

Objective 

In this lesson, we will install 2pcs IR Obstacle Avoidance modules on robot 

car and program the car to follow object movements. The principle of this 

experiment is based on IR detection object. The car receives the signal from 

the IR Obstacle Avoidance module, and then the program will drive the car to 

take actions. 

You must complete 

lesson 1 (assembling the car)

 before you continue on with 

this lesson.
