Understand torque distribution. Parts needed: fischertechnik differential housing (included in many Profi sets), three bevel gears. The Build: Most beginners lock both wheels to the same axle, causing skidding during turns. A differential allows the outer wheel to spin faster than the inner wheel. The Challenge: Build a rear axle with a differential, then push the car around a corner. Notice how the wheels naturally adjust speed without grinding gears. Pro tip: fischertechnik differentials are notoriously tight out of the box. Run them unloaded for ten minutes with 9V to break them in.
The classic robotics starter. Two differential drive motors, two phototransistors, and the fischertechnik “Robo LT” interface (or an Arduino). Tuning hint: Place sensors with an adjustable gap – tight for sharp curves, wide for high-speed lines. fischertechnik projects
