We call the next robot Space Explorer. It is part of our classes in robots and is like the 7th robot in the sequence, but we decided to make it the third robot in "A robot a 'day'". The goal of the robot is to explorer and that's why it has an Ultrasonic Sensor. So get yourself ready.
A nice little robot that can tell if there is anything on top of it. It only uses one touch sensor. The idea of the robot is to be used in classes with students to explore different interesting security options. This robot in particular could detect when the object placed on it gets "stollen". Have you ever watched Indiana Jones? :)
Building instructions for a LEGO Mindstorms EV3 Multi-axles mechanism
НLet’s now focus on the Grid mode of the display block.
The mindstorm motors have an intersting "bug". This bug is that the motors turn absolute to the starting position of the motor.
You can attach a frame around the front wheels to make them more stable and to allow for better aligning. The module extends the front wheel built at BigDaddy Front - front wheels mechanism module for a large LEGO Mindstorms Competition Robot
So far we have created programs that execute actions one after another. But sometimes we need to perform two actions at the same time. How do we achieve that?
Accomplish three FIRST LEGO League missions at once. This is an interesting Large multi-purpose FLL attachment for a box robot that could be used to accomplish a number of missions with a single exit of the field base.
The way sensors and programs work in a robotics system is sometimes not-intuitive for a beginner, but nevertheless very logical. Building a program for a touch sensors for "Press->Go->Press->Stop" using the EV3-G software could be quite challenging at the beginning even for experienced teachers, students and robot builders.
