There are many solutions to this problem. The rover must flip itself without being touched while running and once it has flipped it should stop. You could try combining this with the Turn Over Rover program to include lights. #### Relevant Coding Skills Branching Iteration Functions Variables --> Algorithm Design --> Maths #### Relevant Rover Concepts Ultrasonic --> IR --> Colour Gyroscope Accelerometer Motors LEDs --> Buzzer --> Activity Demonstration ### Setup The most common way to flip the rover is having it drive up a flat vertical surface and fall backwards. Perhaps using the back of a laptop screen, a book, or a wall. These are not the only solutions. See what other driving conditions might make the robot flip. ### Here’s Our Approach This solution can be extended to make the rover reset itself and include LEDs #### Stage 1 Start moving forward to eventually encounter a vertical obstacle. #### **Stage 2** Add a repeat block where the condition is a sensor block that checks if the rover is right way up. This will cause the rover to wait until it is not the right way up. #### **Stage 3** After the loop that waits for the robot to flip we add a motor block to stop the rover. ![](https://images.squarespace-cdn.com/content/v1/60a43bf842d7b601064a8828/8c796e2c-5452-45af-a3f9-fbb9eb1ac363/Screenshot+2023-10-31+083156.png) Example Code ### Related Posts Resources [ ![](https://images.squarespace-cdn.com/content/v1/60a43bf842d7b601064a8828/1639455538805-9NI7CPKR7IYG6D4RBKAN/high+quality+sumo.png) ](/resources/creating-a-sumo-unit) [All](/resources?category=All) [Creating A Sumo Unit For Your Digital Technologies Class](/resources/creating-a-sumo-unit) [All](/resources?category=All) How to run a sumo unit in your digital technologies classroom.
