The Solar System as seen from earth. This model shows the five planets and moon as Ptolemy described them in his famous book, "The Almagest". It describes accurately all the naked eye phenomena of our Solar System. The fact that most of the motions described by this geocentric system are incorrect cannot detract from the fact that to the unaided human eye all these incorrectly described motions appear correct. The use of the Ptolemaic model together with the Copernican model improves student understanding of the motions of the heavenly bodies. 14" high x 20" long. With fully-illustrated instruction book.

Professional entry into measured value acquisition with the Robotics ADD-ON IoT! Together with the Robotics TXT 4.0 Base Set, the sensor station enables the measurement of temperature, humidity, air pressure, air quality and brightness. The sensor station can be programmed and controlled with the ROBO Pro Coding programming software and the ROBOTICS TXT 4.0 Controller and is ideal for teaching topics such as measurement acquisition and transmission as well as control and regulation of actuators and sensors. The measured value acquisition is carried out via the connection of the TXT 4.0 Controller with the fischertechnik cloud, in which the sensor data is stored, collected and graphically displayed. Via the user interface, the so-called dashboard, the various sensor data are permanently recorded (real-time) and the camera, which can be swiveled in two axes, is remotely controlled. The teaching material created to accompany the Robotics ADD-ON IoT set contains 6 experiments and associated solutions.
