Lesson Overview

In this activity, kids will make an obstacle avoiding robot which is an autonomous robot and detect obstacles coming in front of it and avoid it using the ultrasonic sensor. The procedure for making the complete robot requires the following steps:

  • Assembly of the robot
  • Connecting the ultrasonic sensor, servo motor, and motors to evive

Material Required

1 set of the following material per group of 3-5 students:

Lesson Outline

Introduction and demonstration of the robot - 10 minutes
Assembly of the robot - 25 minutes
