LEGO MINDSTORMS EV3

What should you as a teacher know when the students are trying to achieve a program and robot attachment that could reproduce their behaviour 9 out of 10 times. 

In the course section for Advance Sensor Calibration we previously showed you how to find the minimum and maximum value for a single LEGO Mindstorms Color Sensor and to store this value in an array. The program was implemented with the EV3-G software. In this tutorial we are going to find the Min and Max for all the four sensors and to store all the 8 values in an array.

Background

Each minute all around the world roads are reconstructed. Now is the time to take part in those constructions.

Mission

The robot should repair part of a road. The two blocks located in base should be delivered and placed next to the two on the field. At the end of the match the two plates should be touching the black triangle areas on the field.

Scores

For each block touching a black triangle: 30 points per block.

Scoring Requirements

• the robot should autonomiously deliver and place the two blocks from base

In the final video we explore how to trigger the release of the attachment with just a rubber band. The release is triggered with a gear wheel that rotates in a specific way. This saves speed, does not require additional LEGO Mindstorms motor and is precise enough for a competition.
