The previous rubber bands video showed a way to trigger the rubber band without a motor. This video gives one more idea on how to lift an axle and in this way release the rubber band. Use the idea for you LEGO Mindstorms robot constructions.
Five different robot chassis. This is the goal of the series. To present ideas for different design of the robots and especially the robot bases. If the base is stable and balanced, then in could easily be extended. Let's start with the most simple of the five.
Tasks on using the LEGO EV3 Mindstorms Color sensor. Quite fun and useful for different STEM classes or just to get to know the sensor.
Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms EV3 Competition robot without having the whole robot ready yet. We are continuing from part 2 where we finished the 'front' of the robot and now we will extend it so that we could also attach the rear part.
We will build the EasyBot quick robot and will explain how to follow building instructions.
First time programming the motors of the robot using the EV3-G software installed on a computer. We would explore how to move forward/backward and turn with the robot.
Part four of the Catapult series is again about loading the catapult automatically but this time using EV3 brick, motor and sensor. We use a gear system with a medium complexity along with a "standard clutch" available in the LEGO Mindstorms EV3 kits. As a result, at the end of the video, the Catapult loads and fires automatically.
If you get to a solution that is too complex you should always try to improve it. This is what we are doing here. Arriving at a solution for aligning to the wall that has become too complex.
We are describing the Warm gear in this video. This worm gear does most of the magic of controlling how the different gear wheels move on the different axles.
Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.
The integral part "remembers" the errors that the robot has made in the past and we can compensate for those errors. This will make the robot return back to the line that we would like to keep it aligned.
EV3-G program for using the ultrasonic sensor and detecting objects with it.
This is the example program using the blocks available at Blocks Package for Advance Calibration of LEGO Mindstorms EV3 Color/Light sensors. The program makes the robot find the minimum and maximum values and to calibrate the current sensor value depending to the min and max.
This is the fifth and the last run of the Nightbeast team. Robot goes out of the base, do missions:
and stays on the field. It's a common practice for the competitors to left the robot on the field after the last run. This allows them to do some important points at the end of the match.
This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the Emergency Walk mission 10 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission and this is one of the most difficult missions on FIRST LEGO League competitions ever.
Building instructions for the dispenser mission model. The models is used in the Logistics mission of FLLCasts Off-season Challenge 2019.
The program that Nightbeast team use for their first Run in FLL Into Orbit Challange. In this run they solve two missions: SpaceTravel and Solar Panel .
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.
This program is for Uylam - LEGO Mindstorms EV3 Steamship simulator robot. It is made as a lesson, to automatically find the best position for a ship in stormy weather, relative to the waves. The program has two parallel threads. The first one makes the robot move until the gyro sensor detects less amount of shaking done to the ship. Because of all the shaking, the readings of the gyro are all over the place and thats why we made a My Block, which acts like a filter, so that the readings are more accurate. The second thread starts the storm, which is controlled by a Large motor.
NOTE: The program contains my blocks, that will appear broken if you use any version before 1.3.0 of the EV3 Mindstorms Software!
Program for the FIRST LEGO League 2019 City Shaper Swing mission. The attachment is attached on the robot and it we just start the program
