This is a third example for adding an active attachment. This third attachment is now connected to the wheel at the front of the robot. Again, the attachment could be easily extended.
One more example for an active attachment with a system of gear wheels. This time the system is constructed so that the attachment could lift heavy objects.
This robot has a color sensor and this sensor is used for following lines. Additional Mindstorms EV3 sensors could be place on the robot, like a Gyro sensor or a second Color sensor.
In this Episode, we create the next attachment for the box robot two. It is again a pinless attachment, attached to the frame that transfers the motion to a vertical axle.
Need to transfer circular into a linear motion. You need a rack. Here is an attachment with a rack for our box robot.
Recap on the attachments, their purpose and how you should use them.
This one is very special- an attachment that could lock itself on purpose while working.
Sometimes the way an axle is placed is just not suitable for a certain attachment and you should transfer the motion to another axle a few LEGO units above the current.
In this LEGO video tutorial we accomplish 3 missions with the Kriket box robot. A number of actions are performed like Lever, Lift, Drop, Pull, Align. This tutorials shows how to accomplish missions models that are closely positioned next to each other.
How to organize the different robots and group of students when working on lifting the robot.
Where should you lift the robot? Especially if you don`t have the mission model that we are using
Note for the teacher on how to organize the class to use different robot base constructions to accomplish the mission for lifting.
Don't limit yourself to the box and think of different ways to lift the robot.
The balance of the construction of the robot has a great influence on how it will move. This is especially true if you would like to move in a straight line. If the robot is slightly heavier on the right it will move to the right. Here we have two robots - a Five Minute robot and a Box Robot and we will discuss the differences in the constructions and why the box robot is much better than the Five Minute even though it is using the same parts.
The final way for lifting our box robot is by using a scissors mechanism. In this Episode, we would discuss the benefits and advantages of this mechanism.
