Building the Wall follower bot Step-by-Step
Description :
Build an autonomous car with our DIY project! We will create a robot car powered by a Roboki microcontroller, equipped with motors and proximity sensors. Watch as our motorized robot car navigates smoothly by detecting walls and avoiding collisions. Follow our step-by-step guide to construct a wall-detecting robot and discover the fascinating world of DIY autonomous vehicles and build our very own wall-detecting robot with proximity sensors.
This activity is ideal for young engineers over the age of 8 who are eager to dive into microcontroller project.

Before we begin, take a look at the picture of the bot to get a better understanding of the different parts of this wall follower bot.
1. HARDWARE
Let's make it!
We are going to follow the steps in this tutorial to assemble a wall follower bot. Look carefully into each of the images and follow the instructions one by one to make this wall follower bot. 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 wall follower bot.
1.2 How is it made ?
Follow the steps carefully to build the Wall-Follower Robot
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. Take one beam 15 and attach two friction pegs to first and last holes of the beam.
10. Attach the beam 15 to the underside of the block, this step is a bit tricky so do it carefully and ensure that your structure looks similar to the image below.
11. Take one beam 5 and attach two friction pegs to the first and last holes of the beam.
12. Attach the beam 5 on top of the beam 15 as shown in the figure below.
13. Take the 1 by 6 brick with holes and connect two 90 degree pegs to it and then mount it on the Beam 5 as shown in the image.
14. Next, connect the Roboki on top of the structure as shown in image, used the bricks on the underside of robot to alignn with the central beam and fix it in place by applying pressure. During this step make sure you support the body of the bot from below too.so that the pressure does not break the structure.
15. We now need to connect the proximity sensor to Roboki using the angled port connector as shown below.
16. 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" )
2. SOFTWARE
2.1 Let's Code it !
Now that our Bot is ready, we need to programme it using Plode to make a wall-following robot.Follow the step by step instruction in the video given below to programme the wall following bot.
3. What Next?
Challenge!
Convert the robot into a line follower using two proximity sensors to follow a black line on a white surface.
