In the video we improve on the robotics mechanism for pushing the different blocks out of the robot container. We continue from the previous video.
We continue from part 4 where we made a controlled experiment to transfer power from a Mindstorms motor to the rear wheels. The construction was too complex and inefficient and in this video lesson we are improving it by lowering the differential and removing all gear wheels from this LEGO Mindstorms EV3 Competition robot.
In this video we look at the robotics mechanism for dropping the different blocks into the different region on the World Robotics Olympiad 2013 field.
Moving in a grid of objects. That's the large challenge of the World Robotics Olympiad 2015 Junior-High 2015. In this video we would build a robot that can collect the boxes (treasures). The robot would also be able to move around the treasures.
Showing the same run, but from a different angle. This allows you to see more of the way we sensors work and how exactly the robot positions itself.
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.
It has been a long road with the last 8 BigDaddy competition robots video tutorials, but we finally arrived at the Differential Lock.
We continue from part 3 where we finished part of the 'rear'. Power is transfered from a motor to the wheels but having about 16 gear wheels makes it more than complex for this LEGO Mindstorms EV3 Competition robot.
A robot that contains balls and releases them. It counts how many balls to release depending on the "treasures" it has hunted on the field. This is part of the World Robotics Olympiad 2015 Elementary challenge.
This video tutorial contains the final 2 programs for moving straight with a LEGO Mindstorms EV3 robot. The first program is for proportional compensation that just keeps the robot orientation straight, while the second program is for Integral compensation that returns the robot to the straight line when the robot makes a mistake.
Tasks for STEM classroom and home exercise to get you used to using the LEGO Mindstorms Touch sensor. Solve them, build a program, record a video and upload your solutions below.
Extend the previously build attachment for the FIRST LEGO League (FLL) Nature's Fury competition so that we can move the Truck and Ambulance up and down.
In this episode I would like to show you a way to solve the FLL 2012 Medicine mission using an LEGO Mindstorms NXT Ultrasonic Sensor and a system of gears that converts circular motion to linear.
Based on a request we are showing the robot construction with two rear motors instead of a differential. In this way, as a construction, it is closer to more students, but much more challеnging for programing.
Arriving at a final solution. There is still room for improvement on using the Mindstorms Ultrasonic Sensor for aligning to walls, but we hope the whole five videos could give you a good idea of how to start with a problem and reach a solution.
Motors can be placed in opposite directions... opposite .. directions. Robo-builders might have difficulties imagining it so we have build one. One of the motors facing forward, the other backward. It is interesting how this robot turns.
Based on a request from Abdulah we decided to build a tutorial on how to use Hi Technic Color Sensor and EV3-G Software. There is a special block imported in the software that helps you use the sensor.
We continue the discussion of the Robot Design category from the FIRST LEGO League Competition. This time we stop on the programming - how to evaluate the programming of the team during its preparation for the competition.
In this video we are solving Senior Solutions missions: Stove, Gardening, Similarity recognition, Ball game and Wood Working. We will make step-by-step of everything we do on the FLL field.
Tasks for school STEM classes or home exersie. Try to solve them to submit your solutions below.
After several questions about the use of the LEGO Mindstorms NXT Light Sensor with the EV3 software, we have decided to go through this problem in this video tutorial and pay special attention to the Raw Sensor Value Block.
