Challenge students to program their rover to always try and stabilise itself. When complete, the rover will always turn and drive upwards on any tilted surface. Once the surface the robot is driving on is flat, it should stop moving. This means the robot will balance on a seesaw. Students will need to use data from the accelerometer to control the motors based on the orientation of the rover.

Take your maze solving to the next level. In this intermediate challenge, you'll use both IR sensors alongside the ultrasonic sensor to make smarter decisions at intersections and handle more complex maze layouts.
|
||||
|
||||
|
||||
|
||||
Activity Demonstration
|
||||
|
||||
### Setup
|
||||
|
||||
Construct mazes with narrower pathways than in Maze I. Aim for 5-10cm clearance on each side of the rover. Include T-intersections and dead ends to force the rover to make more complex decisions.
|
||||
|
||||
### Building On Maze I
|
||||
|
||||
In Maze I we used the ultrasonic sensor to check ahead and one IR sensor to decide which way to turn. This worked for simple mazes but falls apart when the maze has more complex intersections. Now we'll use both IR sensors to check left and right before deciding where to turn.
|
||||
|
||||
#### Stage 1: Check All Directions
|
||||
|
||||
Create variables for the wall distance on each side. Read both the left and right IR sensors as well as the ultrasonic sensor at each step. This gives the rover a complete picture of its surroundings.
|
||||
|
||||
#### Stage 2: Smarter Turning
|
||||
|
||||
With data from all three distance sensors, the rover can now make better decisions at intersections. Instead of always preferring left or right, prioritise based on which direction has more open space. Use nested IF/ELSE IF/ELSE blocks to handle the different combinations.
|
||||
|
||||
#### Stage 3: Add the Colour Sensor
|
||||
|
||||
Use the colour sensor to detect a coloured finish line at the end of the maze. When the rover detects the finish colour, it should stop and celebrate with LEDs or a buzzer sound.
|
||||
|
||||
### Up Next
|
||||
|
||||
Ready for the ultimate maze challenge? In Maze III you'll add the gyroscope for precise turning and implement a wall-following algorithm.

Create an advanced maze solving algorithm that uses the gyroscope for precise 90-degree turns, implements a wall-following strategy, and organises code with functions for a clean, efficient solution.
|
||||
|
||||
|
||||
|
||||
Activity Demonstration
|
||||
|
||||
### Setup
|
||||
|
||||
Build the most challenging maze you can. Use narrow pathways with only 3-5cm clearance on each side. Include loops, multiple paths, and dead ends. Add coloured sections on the floor for bonus tasks like changing speed or playing different sounds.
|
||||
|
||||
### Building On Maze II
|
||||
|
||||
In Maze II we used all three distance sensors to make better decisions. Now we'll add the gyroscope for precise turning, use functions to organise our code, and implement a proper wall-following algorithm.
|
||||
|
||||
#### Stage 1: Precise Turns With The Gyroscope
|
||||
|
||||
Instead of turning for a set time (which can be inaccurate), use the gyroscope to measure exactly how far the rover has turned. Create a function called `turnRight` that turns the rover exactly 90 degrees by reading the gyroscope and stopping when the target angle is reached. Do the same for `turnLeft`.
|
||||
|
||||
#### Stage 2: Wall-Following Algorithm
|
||||
|
||||
Implement a left-hand or right-hand wall-following strategy. The idea is simple: always keep a wall on one side. If the wall disappears (an opening), turn that direction. If the wall is ahead, turn the other way. This strategy guarantees the rover will eventually find the exit in any simply-connected maze.
|
||||
|
||||
#### Stage 3: Organise With Functions
|
||||
|
||||
Create functions for each behaviour: `moveForward`, `turnLeft`, `turnRight`, `checkWalls`, and `checkFinish`. Your main loop should read cleanly as a series of function calls. This makes the code easier to debug and modify.
|
||||
|
||||
#### Stage 4: Speed Optimisation
|
||||
|
||||
Once your rover can reliably solve the maze, optimise for speed. Move faster in straight sections and slow down when approaching walls or turns. Use the distance sensor readings to adjust speed dynamically.
|
||||
|
||||
### Challenge
|
||||
|
||||
Can you solve the maze as fast as possible? Time your rover and try to beat your personal best. Compare times with classmates to see who has the most efficient algorithm.

Navigate your rover through a maze using the ultrasonic sensor to detect walls ahead and the IR sensor to check for walls to the side. This beginner approach introduces the fundamentals of maze solving with simple branching logic.

### Setup
|
||||
|
||||
Construct mazes with any solid material that is tall enough for the rover IR & ultrasonic sensors to detect. We use boxes or wooden blocks to create our walls. The width of maze pathways will change how difficult the maze will be. For a challenging maze create pathways with 5-10cm allowance from each side of rover to the wall. The larger the width the easier.
|
||||
|
||||
To add complexity to mazes create additional tasks for students to complete in the maze. E.g. use coloured floor tiles or tape on your maze floor and task them to find all colour sections in the maze before they can finish or change speed at different colours.
|
||||
Construct mazes with any solid material that is tall enough for the rover IR & ultrasonic sensors to detect. We use boxes or wooden blocks to create our walls. For this first level, keep pathways wide with at least 15cm clearance on each side of the rover to make it easier for students to get started.
|
||||
|
||||
### Here’s Our Approach
|
||||
|
||||
Solutions to maze challenges can vary in intricacy depending on rovers sensors utilized and maze complexity. Our basic approach only involves the ultrasonic sensor and the left IR sensor.
|
||||
This basic approach only involves the ultrasonic sensor and the left IR sensor.
|
||||
|
||||
#### Stage 1
|
||||
|
||||
We start by creating a variable named wall which represents the distance (cm) from the side of our rover to the maze wall when the rover is placed in the middle of a maze path.
|
||||
|
||||
#### **Stage 2**
|
||||
#### Stage 2
|
||||
|
||||
With an IF/ELSE IF/ELSE block we first check if the rover can move forward. If the ultrasonic sensor doesn't detect anything closer than our wall variable it will move forward. If it did not pass this check, it means there is a wall in the way and it now has to decide where to turn.
|
||||
With an IF/ELSE IF/ELSE block we first check if the rover can move forward. If the ultrasonic sensor doesn’t detect anything closer than our wall variable it will move forward. If it did not pass this check, it means there is a wall in the way and it now has to decide where to turn.
|
||||
|
||||
#### **Stage 3**
|
||||
#### Stage 3
|
||||
|
||||
Our next case, the ELSE IF, will check if the left IR sensor detects a wall. If it doesn't, the way is clear & it will turn left. If it does detect a wall, it will go to the ELSE case and turn right. We then place the whole IF/ELSE IF/ELSE block in a while true loop so it will repeat this behaviour indefinitely.

||||

There are two balance exercises in the simulator, **See-Saw** and ** Balance Board**. Both these challenges require** algorithms ** utilising** iteration ** and a good understanding of the** accelerometer,** as well as the data it produces. Depending on algorithm implementation, branching logic may or may not be used. For example, an algorithm that relies heavily on complex mathematics to process the accelerometer data may not need to use branching.

Level up your sumo robot. In this intermediate challenge, you'll add the IR distance sensors to detect opponents from multiple directions and create a smarter search pattern to find and engage your opponent faster.
|
||||
|
||||
Activity Demonstration
|
||||
|
||||
### Setup
|
||||
|
||||
Use the same sumo arena setup as Sumo I. A circular arena with clear edge markings, 60-100cm in diameter.
|
||||
|
||||
### Building On Sumo I
|
||||
|
||||
In Sumo I we used the colour sensor to avoid the edge and the ultrasonic sensor to detect opponents ahead. This works, but the rover can only find opponents directly in front of it. By adding the IR sensors we can detect opponents to the left and right as well.
|
||||
|
||||
#### Stage 1: Add IR Sensor Detection
|
||||
|
||||
After checking for the arena edge with the colour sensor, add ELSE IF conditions to check the left and right IR sensors. If an opponent is detected to the left, turn left and charge. If detected to the right, turn right and charge. This gives the rover a much wider detection range.
|
||||
|
||||
#### Stage 2: Smarter Search Pattern
|
||||
|
||||
Instead of just driving forward when no opponent is detected, implement a search pattern. Spin slowly on the spot while checking all three distance sensors. Once an opponent is detected in any direction, turn to face them and charge at full speed.
|
||||
|
||||
#### Stage 3: Edge Recovery
|
||||
|
||||
Improve the edge avoidance behaviour. Instead of just reversing and turning a fixed amount, reverse and then spin to scan for the opponent before moving forward again. This prevents the rover from wasting time after hitting the edge.
|
||||
|
||||
### Up Next
|
||||
|
||||
Ready for advanced sumo? In Sumo III you'll use the gyroscope and accelerometer for precise control and defensive strategies.

Create the ultimate sumo algorithm. Use every sensor on the rover to build an advanced strategy that combines precise movement with the gyroscope, defensive detection with the accelerometer, and organised code using functions.

Activity Demonstration
|
||||
|
||||
### Setup
|
||||
|
||||
Use the same sumo arena setup. For an extra challenge, try a smaller arena (40-50cm diameter) to force more aggressive and precise play.
|
||||
|
||||
### Building On Sumo II
|
||||
|
||||
In Sumo II we added IR sensors and a search pattern. Now we'll use the gyroscope for controlled turning, the accelerometer for defensive awareness, and functions to keep our code organised.
|
||||
|
||||
#### Stage 1: Precise Movement With The Gyroscope
|
||||
|
||||
Use the gyroscope to make controlled turns when searching for opponents. Instead of spinning wildly, rotate in measured increments (e.g. 30 degrees at a time) while checking sensors between each turn. This creates a systematic sweep of the arena.
|
||||
|
||||
#### Stage 2: Defensive Tactics With The Accelerometer
|
||||
|
||||
The accelerometer can detect when your rover is being pushed or tipped by an opponent. If a sudden acceleration is detected from behind or the side, the rover knows it's under attack. Program a defensive response: spin to face the attacker and counter-charge.
|
||||
|
||||
#### Stage 3: Organise With Functions
|
||||
|
||||
Create functions for each behaviour: `checkEdge`, `scanForOpponent`, `charge`, `defend`, and `searchPattern`. Your main loop should read as a clear sequence of decisions. This makes it much easier to test and tweak individual strategies.
|
||||
|
||||
#### Stage 4: Adaptive Strategy
|
||||
|
||||
Combine everything into an adaptive algorithm. Start with a search pattern, charge when an opponent is found, defend when being attacked, and always stay away from the edge. The priority order matters: edge avoidance should always come first, then defence, then attack, then search.
|
||||
|
||||
### Challenge
|
||||
|
||||
Battle the AI opponents in the Micromelon Robot Simulator. Can you defeat all three difficulty levels? Try designing a 3D printed attachment to give your rover an extra advantage.

A classic robotics competition challenge. Have your rovers battle in the sumo ring. If a rover is disabled or leaves the ring for any reason it loses the match. There are many possible approaches to staying in the ring while pushing the opponent out. This challenge is a great opportunity to design attachments for your rovers.

### Here’s Our Approach
|
||||
|

Note that this is a simple approach that should be improved upon. Try different tactics and include sensors like IR and Accelerometer to better find and push your opponent.
|
||||
This is a simple approach using just the colour sensor and ultrasonic sensor to get you started.
|
||||
|
||||
#### Stage 1: Stay Away From The Edge
|
||||
|
||||
First we will add a repeat while true loop as we want our code to run continuously. We can then use an IF statement to move backward and turn around if the colour sensor detects the edge of the ring.
|
||||
|
||||
#### **Stage 2: Move Around The Ring**
|
||||
#### Stage 2: Move Around The Ring
|

|

If the robot doesn’t detect the edge it should move in search of the opponent. We can use the ELSE part of the IF statement to move forward.

#### **Stage 3: Push The Opponent**

#### Stage 3: Push The Opponent
|
||||
|
||||
Staying in the ring is most important. After checking for the edge, we can use an ELSE IF (ELIF) in the IF statement to detect if an opponent is in front with the ultrasonic sensor. If it is close use a motor block to set our motors to full speed to charge the opponent.
