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. 

In recent years, we've seen more and more self-driving vehicles being used in farming and transportation. These vehicles can do things on their own like collecting information, figuring out where to go, and actually going there. This needs special kinds of programming and uses a clever technology called machine learning, which is part of artificial intelligence (AI). Autonomous vehicles can move around on roads without any problems. They can help take people and things where they need to go in the smartest and quickest way possible. In this challenge, teams will make a robot that shows what an autonomous vehicle can do
