Before moving forward here is the simple task of building the mechanism and extending the legs. Extend the legs to fifteen LEGO units. 

Experiment with changing the orientation and direction of gear wheels. Here are part of the tasks that you should complete before moving forward with the course.

Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.

Following the principles from the previous video, try to make the attachment that you've built, more stable and durable. 

Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?

In the previous video, we found the correct answer for our task and it is 18.75, or is it?

If you've done the calculation following the previous tutorials you would arrive at a result of 18.75 rotations. But this is not the correct answer. The calculation is wrong, because the math model that we've built, although kind of obvious, is not correct. When experimenting the correct number of rotations would be 37.5. This is a large difference. Two times larger. Exactly two times large. Something should be happening here - and this thing is "planetary mechanism"

Third wheel experiments, changes in the robot, students could choose the task all by themselves. Make sure you have a lot of fun and students complete their tasks. Here is what you should know when conducting this class.

The goal of this lesson is for students to have fun with a new robot. 

There are two types of inertia to familiarize you with. You know of one intuitively, the other one is more obscure. Both must be considered when building your own robots, especially in the future for competitions.

In the second run Nightbeast team solves different tasks from two missions - M05 Extraction and M06 Space Station Modules:

1. Insert the Tube Module into the Habitation Hub port, west side 
2. Move all four Core Samples so they are no longer touching the axle that held them in the Core Site Model
3. Place the Gas Core Sample completely in Base

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M08. AEROBIC EXERCISE. This again is a very interesting mission from the competition. We could learn a lot of basic principles in the field of robotics. This mission requires the robot do to something very fast and many times. 

Sweeper - a special vehicle designed for cleaning streets, pavements, and runways. The first sweeper is believed to be a construction patented on September 4, 1849 in the United States by CS Bishop, it was pulled by a horse cart. Until the end of the 19th century, 315 solutions for sweepers have been patented in the USA. The first sweeper with its own drive was patented in the USA in 1868. 

Regarding the parts of our robots

Here's what one of our robots looks like

This is the first run of Team "Nightbeast", with which they solve M01 and M02 from FIRST LEGO League 2019 Into Orbit:

1. Starts with the Vehicle Payload
2. Places the Supply and Crew Payloads and rolls them to east.
3. Pushes the Solar Panel Array to the opposite side
