The power of State Machines. Gapped and Crossed Line Following with LEGO Mindstorms EV3

There comes a time when you need to program the robot to "follow a line, but if another sensor detects something you would like to stop, do some work, and then continue following the line". This is applicable to competition robots as it is applicable to real-life robots.

There comes the State Machine Pattern. An advanced and very powerful concept that allows you to easily implement complex robot behaviours with a simple, well-organized, extensible, bug-free program where the robot could be in 1,2, 10 or 100 states and you will still be able to manage the complexity of the world around the robot.

Box Robot for Robotics Competitions. Brick Accessibility and Cable Management

Sometimes robot builders are so overwhelmed with the process of constructing a robot that they forget two very important parts. The brick should be accessible and the cables should not get in the way. These are referred by us as Brick Accessibility and Cable Management.

Hardcode read of calibrated value for Light/Color LEGO Mindstorms sensors

Following the Advance Sensor Calibration course section, we found the min and max values detected by each sensor. Now it is time for the real deal of the calibration. Detect the current value from the sensor and find what is the percentage of this value for the range between min and max.

FLL 2017: How to accomplish Hydrodynamics Fountain (07th), Faucet (18) and Slingshot (17th)

The after season review continues. No. We are not publishing a single solution for the next season before it is over, but let's learn from the previous season. The current tutorial is about three missions at once on a single run with the robot. Most FIRST LEGO League teams try to accomplish one-two missions on a single run out of the base, and three is really what makes the difference
