Middle School Level

 

Task 1: Hand Track

Instructions:

Your pet robot likes the smell of your hand! Code an algorithm that allows your robot to maintain a distance of 10 cm from your hand. As you move your hand forward or backward, the robot has to react accordingly to maintain its 10 cm distance. Hint: Use the ultrasonic sensor.





 

Task 2: Line Following

Construct the following path and create a line-following algorithm.

 

 









 

Task 3: Cleaning Robot

Instructions:

  • An object is randomly placed within a 40 cm radius from the robot

  • The robot must find the object using an ultrasonic sensor

  • The robot must drive towards the object and push it outside the circle

  • You may add a piece of cardboard to the front of your robot to larger than 5x5 cm, to increase the surface area of pushing.

  • Either foam or empty can is allowed to use as obstacle and the size of obstacle should be around 25 cm3



 

Task 4: Get Creative!

In this task, you will have the opportunity to showcase your coding skills and creativity. Using Scratch or any robot of your choice, create your own task. Think of real world problems and try to solve one of them. When you submit the video for this section, please include a description of your task that clearly explains what you are trying to achieve.










 

 

 

 

 

 

 

Point System

Eligible Robots:

  • No restrictions

  • No remote control 

 

Task 1: Hand-Following (total points 3+2)

  • 1 point if the robot is able to move forward to maintain 10 cm from hand

  • 1 point if the robot is able to move backward to maintain 10 cm from hand

  • 1 point if the robot is able to stop when distance is 10 cm from hand

  • 2 Bonus points if PID is used

 

Task 2: Line Following (total points 15)

Points will be given based on successful completion of portions of the path:

  • 1 point for completing the 40 cm strip

  • 2 points for completing the 145° angle

  • 1 point for completing the 30 cm strip

High School Level

Task 1: Obstacle Bridge

Instructions:

There are two pathways to cross the river; one of the pathways is blocked by a large object (red). Your robot (blue) must identify the clear bridge and cross over using that bridge. 

Some specifications: 

  1. Initial position of the robot: 40 cm away from the bridges horizontally, right in the middle between the two bridges vertically. 

  2. The robot should detect and determine which bridge is safe to cross at the beginning of this challenge. 

  3. The width of both bridges are 30 cm. 

  4. Either foam or empty can is allowed to use as obstacle and the size of obstacle should be around 25 cm3

 





 

 

 

 

 

 

 


 

Task 2: Bus Stop

Instructions:

Think of the robot (blue rectangle) like a bus that stops when it sees a person (object) waiting at the station (red squares), it will stop (for 5 seconds) to pick up the passenger.

You will need to use the ultrasonic sensor (sonar)

Hint: Keep your sensor pointing to the right

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Task 3: Find and Snatch

Instructions:

An object is randomly placed within 40 cm from the robot in any direction. The robot must locate the object using an ultrasonic sensor (sonar) and drive towards the object. Once the robot stops in front of the object, it must pick up the object from the ground using its arm and drive out of the circle.

Some specifications:

  1. Either foam or empty can is allowed to use as obstacle and the size of obstacle should be around 25 cm3
