Product Description

The TXT 4.0 Controller delivers a wide range of new features with 512 MB RAM of storage space and 4 GB eMMC, three servo outputs and a capacitive touch display that supports gestures. The improved WiFi and Bluetooth module offers a wireless interface that works for many different applications. Another interface is the USB host port, which can be used to connect the fischertechnik USB camera or USB sticks, for example. Up to eight additional controllers can be connected to one controller as extensions. Thanks to the narrow housing, the controller integrates perfectly into the models. Firmware updates are downloaded automatically via the cloud to ensure the models always stay up to date, while retaining custom programs. The ROBO Pro Coding software can be used for graphic programming, as well as Python. It is not dependent on any operating system, and can also be used on mobile devices.

Accompanying teaching material:

fischertechnik Education products include comprehensive, freely accessible teaching materials. These have been developed together with teacher training colleges, teachers and didacticians and are ideally suited to the needs of the classroom. In addition to the topic introduction, lesson plans with task sheets and educational plan references are available.

- The topic introduction provides content that can be optimally used for lesson preparation and integrated into the lessons. Definitions, history, basic knowledge and much more are provided.

- The teaching material includes an overview of the learning objectives as well as the time required for the tasks.

- In line with the curriculum-relevant topics, various tasks are included within which different experiments are dealt with.

- The tasks are divided into a construction task, thematic task and experimentation task. In this way, one progresses from building, to learning technical content, to applying the acquired knowledge.
