Previous history of the model

We first constructed a robot from just from Fischertechnik bricks. Then we started adding 3D printed parts. First, we added the motors on the 3D printed chasis. Than we added all the sensors and the TXT. Finally, we added the wheels. Than we started adding some advanced things like relays, slope detectors and the keyboards. We have been working on this robot for more than 1.5 years. We have been to the European championship with the previous version of this robot. We have a total of 9 sensors. 6 of them are used for navigating the walls, 2 are color sensors and there is the slope detector made out of a LED diode and the photosensor.

Construction and Hardware

We tried to make our hardware as durable as possible so our robot can navigate the maze with ease. These are the files we used to print the parts of our robot.
