MODEL DESCRIPTION / TASK

The students plan and build a driving robot that can navigate an obstacle course. The robot turns on and starts its driving program when the On/Off button is pressed. The same button can be used to stop the robot's movement.

EVERYDAY RELEVANCE

The automatic triggering of a process and the autonomous driving of a robot have a strong motivational effect on students. Up to four extensions of the basic task allow for the individualization of the topic.

Integrating this topic into pre-vocational orientation can be beneficial with regard to information technology career fields. Automated switching by capturing physical quantities is used in many areas. Automated movement of objects is becoming increasingly important, particularly in home technology (e.g., vacuum robots, lawn mowing robots) and automotive technology.

Key questions

Where can an automated driving robot be used in daily life? (Communication)
What functions does the robot need to fulfill? (Collaboration)
Under what conditions should the system switch on or off? (critical thinking)
What needs to be considered so that the robot can be used at different locations and the system functions as robustly as possible? (creativity)

Information and notes

Methodical and didactic tips

Differentiation options

Depending on the duration of the series of lessons and the strength of the pupils

the position of the obstacle blocks and the routes can be specified,
the position of the obstacle blocks can be measured by the pupils,
the route program blocks can be specified,
measure the routes themselves,
program the routes themselves,
obstacles are collected using arms.

Motivational aspects

All students are familiar with the topic of autonomous driving robots from daily life. In many househoulds, robotic vacuum ceaners and lawn mower have long been part of daily life, along with many other smart applications. Semi-autonomous cars are becoming increasingly common on the roads.

Additional material

If available, a robot from film and television (BB8, R2D2, Wall-E), a robot vacuum cleaner or another real object from the field of robotics/conveyor vehicles can be used for the introductory phase of the topic. Drawing media (paper, whiteboard or projection screen)
