Robots for Climate

On 20 September 2019 FridaysforFuture had called for worldwide climate strikes. Hundreds of thousands of people around the world took to the streets to protest for more sustainable industry and long-term climate policies to fight global warming. Technological progress and the protection of the environment do not necessarily have to contradict. Quite the opposite, we will present 3 robots which show that technology can be used to achieve climate goals. Planting trees is the most efficient strategy to recover biodiversity and stop climate change. However, this method requires lots of human power. The GrowBot automates this task resulting in a planting rate that is 10 times faster than trained human planters. In contrast to planting drones, the little truck-alike robot not only spreads seeds, instead it plants small trees into the soil which gives them a better chance to survive and foster reforestation. The bio-inspired Row-bot¬†converts organic matter into operating power just as the water boatman (a bug). The robot’s engine is based on a microbial fuel cell (MFC) which enables the robot to swim. Researchers from the Bristol Robotics Laboratory developed the 3D-printed Row-bot for environmental clean-up operations such as harmful algal bloom, oil spills or monitoring the impact of (natural or man-made) environmental catastrophes. Next-level-recycling like in the movie WALL¬∑E can be expected with the sorting robot RoCycle which is developed at MIT. Other than classic recycling machines the robot is capable of distinguishing paper, plastic and metal carbage by using pressure sensors. This tactile solution is 85% accurate at detecting in stationary use and 63% when attached to an assembly line. Through cameras and magnets, the researchers aim to optimise recycling to help cleaning Earth.
