Building the Line follower bot Step-by-Step

Description :

Line follower bot made using Roboki, Proximity sensors and Motors.

Construct a cutting-edge line follower robot with our hands-on build! Utilize the Roboki microcontroller, motors, and proximity sensors to create a robot that autonomously tracks and follows a designated path. Our comprehensive guide will help you assemble a robot with advanced line-following technology, perfect for exploring sensor-based navigation and autonomous robotics. Ideal for tech enthusiasts and budding engineers, this project offers hands-on experience with robotic pathfinding and motorized line following. Dive into the world of robotics and build your own line follower today.

This activity is ideal for young engineers over the age of 8 who are eager to dive into microcontroller projects and fun games.

We are going to follow the steps in this tutorial to assemble our gaming bot.

Let's make it!

We are going to follow the steps in this tutorial to assemble our line follower bot. Look carefully into each of the images and follow the instructions one by one to make this Line following robot. The colour of the blocks and parts used in the construction might differ from original, So carefully follow the instruction given below.

1.1 What do we need ?

Given below are the materials required to build the Line following bot.

1.2 How is it made ?

Follow the steps carefully to build the Line following Bot.

1. Take the two motors and attach the 3 pegs as shown below.

2. Place the 15 by 11 block on a flat surface.

3. Connect the motor to this block as shown in the image.

4. Similarly, connect the other motor to this block.

5. Once the setup is ready carefully attach axle 5 to each of the motors. With this we have created an extension to mount our wheels on.

6. Connect wheels to axles on both sides.

7. Take the pin connector and connect it to the opposite side of the motors on the block as shown below.

8. Now, take the caster wheel and by using the block joiner connect it to the pin connector on the block

9. Next, take the Roboki and attach two pegs to it.

10. Next, connect the Roboki to the 15 by 11 block as shown in the image. During this step, make sure to support the body of the bot from below to prevent the structure from breaking due to the applied pressure while connecting.

11. We now need to connect two proximity sensors to Roboki Port A and Port B using the angled port connectors.So for that we take one proximity sensor and connect it to an angled port connector and attach it to the Roboki port as shown below.

12. Similarly, take another proximity sensor and connect it to an angled port connector and attach it to the other Roboki port as shown below.This step completes the bot construction.

13. Now we must connect the motors to the Roboki. Remember the ports to which each motor is connected and programme it accordingly. (Refer to "Roboki Session 4: Spin Wheel.")

2. SOFTWARE

2.1 Let's Code it!

Now that the design of our Bot is ready, we need to programme it using PLODE to make it a line following robot. Follow the step by step instruction in the video given below to programme the Line follower bot.

3. What Next?

Challenge !

Create a complex track with sharp turns, intersections, and varying line thickness. Adjust the bot to handle these variations, calibrating sensors for smooth movement without deflections.
