The Preschool Category is an introductory, beginning-level competition which focuses on developing computational thinking skills. Students have to explore the use of renewable energy, the development of a sustainable transportation system, and/or the implementation of waste management. Students will have to use their robotics skills to complete different eco-friendly missions! 

It is important for sustainability efforts to be applied at the best place outside our homes, our schools! That's why the project for GRG Mobile Robotics I is project Green School! Your robot will perform several tasks, such as, planting seeds, collecting rainwater, activating solar panels, finding the recycling bin, and even showcasing the school's sustainability mascot. But don't forget that your robot is in a school, so it needs to be intelligent enough to avoid obstacles. 

Robots can also support the construction of buildings to reduce the need of manpower and carbon footprint. That's why the project for GRG Mobile Robotics I is project Green City! A Green City is a special city that is built in a way that helps people, the environment, and the future. It is designed to be a good place for everyone to live, work, and play. It takes care of nature and tries not to harm it, so that even future generations can enjoy the same beautiful environment.

The theme for this category will be Green World! In a Green World, countries want to use more renewable energy. One type is wind energy, which comes from the wind. In this challenge, each team's robot has important jobs: moving old wind turbines to a special place, putting new wind turbines where they should be, and taking energy tokens to a big battery. 

Access to clean, drinkable water has always posed a significant challenge for developing regions. In giant water storage tanks, there are already solutions to bring large amounts of potable water to people. However, some areas still have difficulty receiving aid due to harsh terrain and undeveloped roads. For the competition, participants will be challenged to design a robot using the provided Stick ‘Em Kits to collect and deliver water cubes to the villages!
