The Karel platform can be a good start in different hard, and open contests as line maze, wall maze, firefly line follower, and pentabot.
Karel User’s Manual details both, the hardware, and the software of the Karel robotic platform. The purpose of the manual is to help beginners to understand how to make, and use the robotic platform Karel. You will find information about the final prototype, but also information related to the evolution of the platform, and the intermediary prototypes. You also can find in one place the links to the different documents necessary to produce and use Karel.
Karel Upper Board Design contains the documents to manufacture the upper board of the Karel platform final prototype, which is an improved version of Karelino board. The upper board contains next modules: electronic switch; voltage regulators (5 V, 3.3 V, and 7 V); ATmega32U4 microcontroller; Bluetooth module BTM-182; level shifter between 3.3 V and 5 V; motor driver with DRV8833PWP; trimmer potentiometer; four user LEDs; four user pushbuttons. To participate in Robotor competition is not necessary to assembly the Bluetooth module.
Karel Lower Board Design contains the documents to manufacture the lower board of the Karel platform final prototype. The lower board accomodates three electronic modules: 2s Lithium Polymer battery charger and protection circuit; line sensor with 4 IR sensors. The lower board is also the chassis of the Karel platform; the motors, the battery and the third wheel are placed on it. We designed a single sided PCB for lower board. To participate in Robotor competition is not necessary to populate the PCB with the components for charger, and battery protection circuit.
The Robo Scratch is a course available on the Moodle platform of the Scientix portal, available in all European languages. The course helps you to understand how to code different behaviors for your robots.
