Oakwood's 4th, 5th, and 6th grade robotics team, Techie Pizza, continues to make progress in preparing for regional championships that will occur March 7th at the Northern California FIRST LEGO League Innovation Expo.
During the regular season, the team was challenged to identify a problem with a building or public space in their community and chose the problem of rental scooters ridden illegally on sidewalks. While scooters are environmentally friendly and convenient, pedestrians are being injured and even killed. The team employed an accelerometer and demonstrated that scooters operated on streets and sidewalks produced different vibration patterns.
Now, the team has modified an electric scooter to prototype and prove their solution. They adapted the scooter's drive electronics and used CAD to design an enclosure into which they have installed a small computer and sensors. They have written software to gather accelerometer data and are training machine learning models to automatically tell the difference between sidewalks and streets. They hope to produce software that can be installed onto existing rental scooters that will slow down and sound alarms to encourage users to avoid riding on the sidewalk.
