Bult Bot - One Step Motor Attachment LEGO Robot
In all building instructions for LEGO robots it is important to have the motors attached to the brick in more than one place. In the following construction, there is a beam connecting the two motors which has exactly this purpose. It makes the construction much more stable. Try removing this beam for example and see what will happen. Would the robot be able to move?
Many different types of wheels could be used. Both NXT and EV3 or from other LEGO technic series.

Coin counter program
This program counts coins. It is meant to work with Scrooge McRobot. For it to count the coins correctly, you must change the coins border sizes to match the measurements of the coins that are being used.

Turning two axles, one at a time in opposite direction with one motor and two rubber bands
With this attachment we just share an idea. The attachment was build by an FLL team called Brother in Arms and they needed a way to turn two axles in different direction, one at a time. The attachment was not used in the final robot design and construction, but presents a nice idea.

Program for detecting the maximum speed for Energy Accumulation and Conservation Part 7
One of the interesting things in this sequence of videos is the program. The program detects when the system has reached the maximum speed and then stops the motor from rotating. We detect this with the EV3-G software

Escape Velocity. Mission 11 from FIRST LEGO League 2018 Into Orbit Challenge
Background
Soon after a launch, rocket engines often separate away from spacecraft by design, but that’s long before the spacecraft leaves the pull of gravity. So why doesn’t the spacecraft fall back to earth?
Mission
The robot needs to impact the strike pad hard enough to keep the spacecraft from dropping back down.
Scores
- Get the spacecraft to go so fast and high that it stays up, by pressing/hitting the strike pad: 24
- Possible scores: 0, 24
Scoring Requirements
- The result must be visible at the end of the match.
- Activate the spacecraft by pressing/hitting the strike pad. > Only allowed method. Must be observed by the referee.
