A mini industrial robot arm.
What it teaches: Inverse kinematics, stepper motor control, and end-of-travel sensors.
Advanced twist: Control it with an Arduino or Raspberry Pi using fischertechnik’s “TX Controller” or build your own H-bridge driver.
Before diving into specific projects, you must understand the hardware. fischertechnik has three unique advantages over other building systems:
If you’re tired of proprietary controllers, the good news is that fischertechnik uses standard 9V DC motors and 5–9V sensors. You can easily break out the 6-pin “JST” connectors and interface with:
I’ve even seen builders replace the control box with a small PLC for industrial training.
The iconic fischertechnik project featured on countless kit boxes.
What it teaches: Crank mechanisms, gear ratios, and timing.
Build notes: Use a 10:1 gear reduction to slow the motor, then a connecting rod to convert rotation into linear punching motion. Add a microswitch to auto-cycle.
This is the "Hello World" of fischertechnik pneumatics.
Motion Sequence: Rotate -> Lower -> Squeeze -> Lift -> Rotate -> Release.
Difficulty: Medium.
The classic robotics starter.
Parts needed: 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.
Before diving into projects, let’s look at what makes this system unique:
You cannot just "wing it" with fischertechnik. Here are professional tips:
