BOB3

from Wikipedia, the free encyclopedia

BOB3 ( proper spelling B · O · B · 3) is a microcontroller system in robot form specially designed for the educational sector . The concept consists of the BOB3 robot with an AVR microcontroller , an ISP programming adapter with USB connection (ProgBob - in the form of an astronaut helmet), and the web-based ProgBob programming tutorial. The robot has an infrared sensor, a temperature sensor and six touch sensors as inputs and an infrared LED, two multicolor LEDs and two white LEDs as outputs. The robot board can also be soldered together by the students themselves. Then, in combination with the web-based learning environment , the students get to know textual C / C ++ programming step by step .

development

The microcontroller system and the learning environment with programming tutorial were developed in 2016 by the company nicai-systems in cooperation with several schools from the Aachen region and tested in a model project with over 200 participating students in several schools in spring 2017.

ProgBob learning environment

The web-based tutorial is designed for secondary level I and is the core of the concept. Within the learning environment there are small, basic insights into C / C ++ programming, data structures , sensors , color models and data transmission . The programs are written in an Arduino- compatible syntax, the examples in the tutorials are structured intuitively: With the touch sensors and LEDs, BOB3 becomes a flashlight or a code lock, with the IR sensor the students develop a parking aid or an alarm system. With the temperature sensor, BOB3 can differentiate between cold and warm and display the information with the eyes based on the color. For further motivation, there are also games in which the source text can be changed by the students.

Alternative programming interfaces

Use in schools

BOB3 is now being used successfully in some schools. Two different application scenarios have developed:

  • The students solder their own BOB3 together, learn to program with it and are then allowed to keep the robot.
  • The students learn to program with finished BOB3 in class. The robots stay in the school.
