Improving FLL Robot Game. Gears skipping a tooth. Common problem
One of the very common problems with the LEGO Mindstorms and LEGO Technic Gear wheels is then a tooth is skipped. In this video, I would like us to discuss this challenge and how do we solve it.

Improving FLL Robot Game. Beams on all axles of the gear wheels
The most stressed wheel in our system is the driven wheel. We've already fixed the problem with the driving wheel of the scissor mechanism and now it is time to look at the drive LEGO Mindstorms wheel.

Improving FLL Robot Game. Task for extending axles.
The important task before the solution. If you haven't done it already, then attach a new axle at the front of the robot and extend the construction with gear wheels and axles to reach the two legs at the two sides of the robot.

FLL 2017: Attachment The Manhole Cover (08th) Mission
We have to admit. This is quite an interesting missions. There is a Manhole cover and it must be turned upside down. Well, the robot must turn it. Again LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro is used as a base for the Robot.

FLL 2017: Attachment To Accomplish The Hydrodynamics Fountain (07) And Faucet (18) Robot Game Missions
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

FLL 2017: Attachment For Accomplishing The Slingshot (17th) Mission
These are building instructions for an attachment accomplishing the FIRST LEGO League 2017-2018 Slingshot mission. The based of the robot is LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro

FLL 2017: Large Multi-purpose Attachment for Robot Game Missions (01), (06) and (08)
Here is another great example of a large multi-purpose attachment used in FIRST LEGO League competitions. This one is specifically for the 2017-2018 Hydrodynamics competitions and is doing a number of missions. (01) Pipe removal, (06) Water Treatment and (08) Manhole cover.
The attachment consists of two parts. The first part is placed on the robot while the second part is in front of the robot and the robot pushes it. While working on the field the robot leaves the second part on the Water Treatment plant and when returning back collects it back and returns to base.
The goal of the attachment is for you to build it and experiment with it with the existing field. Use Box Robot 2 as a robot base on which to add the attachments.

Coach Pins, Penalties and Meteoroids For FLL 2018 Into Orbit Challenge
FIRST® LEGO® League mission requirements need to be achieved by your robot through its programs and its use of equipment. You’re allowed to hand-rescue your robot, but that does cause this penalty. Be sure to pay extra attention to the rules where they talk about “Interruptions"
Penalty
- If you interrupt the robot: minus 3 each time
- Possible penalty totals: −18, −15, −12, −9, −6, −3, 0
Scoring Requirements
- Interruption needs to be observed by the referee.
- Upon penalty, the referee will place one penalty disc in the southeast triangle as a permanent interruption marker.
- You can get up to six such penalties.
- If a penalty disc comes off the triangle, it is simply returned, with no effect on score.

FLL 2018: Nightbeast Multi-purpose Attachment. M11, M13
This is the attachment of Team "Nightbeast", with which they do:
M11–Escape Velocity and M13–Observatory
The Observatory result depends on the model. Sometimes the pointer is in the orange area otherwise in the white area.
