Presenting a sequence of videos, materials and programs for accomplishing the WRO Elementary 2013. We present arrays, menus, counting colors and many more.
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.
Тasks that are both laborious and futile are described as Sisyphean. Sisyphus was the king of Ephyra. He was punished for his self-aggrandizing craftiness and deceitfulness by being forced to roll an immense boulder up a hill only for it to roll down when it nears the top, repeating this action for eternity.
This attachment presents a way to mechanically align the robot to a mission model and solves the Cloud mission from FLL 2014.
Do your best as a teacher to make sure students are expanding their vocabulary on every occasion.
This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees.
It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion
The following tasks aim at showing the friction effect. Let a robot move on stone/wooden floor and then on a carpet or surface which creates more friction (vinyl fields are very suitable for the experiment) and the frog will instantly start moving. An important feature of friction is that it is created between two surfaces which means that we should increase the friction between the surface and the legs of the frog so that it can jump. As it is difficult to change the surface of the floor, students’ task will be to put something under the feet of the frog in order to increase friction.
