In the previous part of the video lesson we showed how imprecise a chain LEGO Mindstorms robot could be if its positioning does not rely on sensors, but only on the use of move block. In this tutorial we will show the same thing, but using robot on tires.
We often use the rotation sensor without even realizing it. This sensor performs a very important fucntion in our robots and now we will see what it is.
In this tutorial we accomplish the Elevated places with the Whakatae - LEGO Education SPIKE Prime Competition Box robot mission. It is important to be able to go over the mission model and at the end with a simple mechanism we just push the mission model at the end
Two missions in one. This attachment accomplishes the Hydrodynamics Fountain and Faucet missions from the FIRST LEGO League Hydrodynamics 2017-2018 competitions. The attachment shows a really interesting and widely used approach of a single attachment that is used for two, three and even more missions. This is a standard practice for many of the advanced teams, especially those that reach the finals. The based of the robot is the LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro
You will need to attach the Angled beam on the 5th hole from the top on the left of the robot, as shown:
You can find the attachment here.
Based on a request we are showing the robot construction with two rear motors instead of a differential. In this way, as a construction, it is closer to more students, but much more challеnging for programing.
- you should attach it to the motor, depending on the orientation of the motor
This LEGO attachment connects a LEGO Mindstorms EV3 Motor with a LEGO Technic Linear Actuator. The connection is through a couple of gears which makes the whole instructions quite interesting and useful as an example.
The attachment was used during FIRST LEGO League 2014 Robotics competition.
