In this video tutorial, we demonstrate an attachment that is activated when we reach the mission model. That means the attachment is not activated by a motor but by the movement of the robot. We accomplish the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model, where we have to move and bring cargo to the mission model and leave the cargo there.
After the first box robot course and its enormous success, we decided to build a second box robot. This time with fewer parts and with only three motors. The EV3 set comes with one medium motor and this robot will be easier for new teams. It is also lighter and more simple. Take the course and learn the ideas that we have in mind in simplifying a robot. Use this course with students and try to experiment to make the attachments and construction even simpler.
This course if used by teams, mentors and students to structure the preparation for the Robotics Game of the FIRST LEGO League Robotics Competitions. One thing that is common each year at FLL is that experience matters a lot. Our goal with this course is to quickly bring new teams up to speed with experienced teams and to share some new tricks, patterns, constructions with the more experienced teams.
After the great success of the previous two Box Robots Courses (Box Robot 1 and Box Robot 2) we are improving the construction even further showing one more way to build Box Robots and to resolve some of the challenges that we all had with the previous robots.
Of course attachments are a great topic of the robots. We show the general way in which one is to build attachments with the Knob Wheels and Gear Wheels mechanisms.
This video is part of a series where we show you how our Box Robot accomplished the M10 Steel Construction mission 10 out of 10 times. The attachment is a basic lever and all the 'heavy lifting' is done by the x-y movement of the Dominator robot. This mission is one of the hard missions, because the construction is big and heavy and this requires precise movement of the robot.
This is the attachment to accomplish Fll 2019 M10 mission with the Dominator robot. You can see how to attach the attachment to the robot in this tutorial.
Before moving forward here is the simple task of building the mechanism and extending the legs. Extend the legs to fifteen LEGO units.
Experiment with changing the orientation and direction of gear wheels. Here are part of the tasks that you should complete before moving forward with the course.
Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.
Following the principles from the previous video, try to make the attachment that you've built, more stable and durable.
Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?
In the previous video, we found the correct answer for our task and it is 18.75, or is it?
This robot is a veriation of the Spark Bot without steering wheel.
The goal of this LEGO Mindstorms building instruction is to spark the imagination when the base of the construction is very simple. Just two motors with the brick above them and one of the most classic ways to attach them together - with angled beams.
The construction could use EV3 or NXT wheels, so chose wisely. As a robot chassis base, it is suitable for all kinds of extensions. An interesting thing is the motors are attached to each other with a frame which is getting very popular in the EV3 world.
