"The devil is in the details". We are improving the Rubber band attachment with a Flywheel by introducing a few small, but important modifications that make the whole robot attachment more stable and reliable. With the conclusion of the series this attachment could be used as a basis for some very interesting STEM demonstrations on energy accumulation and conservation.
This video tutorial reviews the EV3 Gyro Sensor and the HiTechnic Gyro Sensor for the LEGO Mindstorms NXT robotics Kit. We compare the two sensors and demonstrate them in action.
This is version 2 of the LEGO Mindstorms Grabber. It makes use of 4 gears to make both levers active.
The program that Nightbeast team use for their second Run in FLL Into Orbit Challange. In this run they solve Mission 11–Escape Velocity and Mission 13–Observatory.
In this tutorial, we demonstrate how to square on a wall. The process requires the robot to crash into the wall, or another solid object on the field, and to "stick" on it. If the robot was to an angle to the wall, the final result of that crush will be that the robot is now fully perpendicular to the wall. As we say in competitions - the robot has squared or aligned itself.
These are instructions on how to build the:
for the FIRST LEGO League 2019-2020 City Shaper Challenge.

As with the two sensors we have covered so far, the color sensor can be used as a condition for the wait block, the switch block or the loop block. The color sensor, as well as the ultrasonic sensor, has several modes. Nevertheless, these modes are substantially different. While the ultrasonic sensor has two modes - one to work in centimeters and one in inches, the color sensor has three modes - one for detecting the color of an object, one for ambient light and one for reflected light.
