Yes I think robots can participate in a lot of ways in the effort to prevent climate change!
They can act at different levels:
– Robots are already helping making waste sorting easier and more efficient in some recycling facilities
– Drones and underwater robots help to monitor the environment: coral reef, forest, glaciers, etc.
– Robots are also used to optimise manufacturing processes to reduce energy consumption and to eliminate waste with fewer human errors and better usage calculations.
– There are a lot of new start-ups that are using robots to plant trees, to pick-up waste in the river, or even collect solar energy (check out this robot: https://www.liquid-robotics.com/wave-glider/how-it-works/)
Have a look on the internet, there are a lot of cool robots doing really interesting things for the environment 🙂
