A mechatronics engineer works to automate the transfer of materials and goods, and the manufacturing process. Their tasks involve identifying areas for task automation, designing, developing and testing potential mechatronic devices, and implementing design solutions.
A typical tea bag has somewhere between a gram and two grams of stuff in it. If the entire contents were nothing but fructose, and that fructose completely dissolved when you made your tea, you'd consume between 4 and 8 calories (carbohydrates contain 4 calories per gram) per cup of tea -- so that's the ceiling.
Steep your tea bag in hot water for at least three minutes to allow the tea to release its full potential. Before you put the tea bag in the cup, give it a gentle shake. This will loosen any compacted tea, allowing the water to flow freely through the tea leaves. Once the tea bag is in the water, there's no need to move it around.
