Youth research 2017Young researchers called to the 52nd round
"The future - I'm shaping it!" - This is the motto for a new round of the youth research competition. Young people who enjoy and are interested in mathematics, computer science, natural sciences and technology can now apply with their research project.
Johannes Meier (18) wants to make life easier for forestry workers. To this end, he developed a measuring device for chainsaws that enables the operator to quickly and precisely cut felled trees into pieces of a specified length without the need for any other tools. All the operator has to do is move the rolling saw chain along the trunk. The distance covered is shown on a display integrated into the saw's air filter cover. This principle of measuring is known from the bicycle speedometer: Seven small magnets are attached to the circumference of the chain drive sprocket at regular intervals. The rolling chain turns the wheel and the magnets are moved past a sensor. A microcontroller then calculates the distance traveled from the magnetic pulses.
