ROBOTICS TXT 4.0 Base Set

Make the basics of robotics understandable and sustainable!

The fischertechnik Robotics TXT 4.0 Base Set is the perfect start to programming like the pros! In addition to the camera with image processing, the comprehensive construction set contains an ultrasonic sensor, two encoder motors, a track sensor, a phototransistor as well as two buttons and two LEDs. The models can be programmed and controlled using the ROBO Pro Coding graphical programming software and the ROBOTICS TXT 4.0 controller. Beginners can use ready-made example programs, while advanced and professional users can get started directly in a Blockly programming environment or in Python. Included are 12 exciting models, ranging from pedestrian traffic lights to a barrier, a barcode scanner and mobile driving robots with encoder motors, camera, track and distance sensors. In addition to introductory and basic information, the comprehensive teaching material includes 20 experiments with solutions for the 12 models.
