How should an instructor use this course when working with students and a group of students in school
In this video tutorial, we are accomplishing three missions in a single run from the FIRST LEGO League MASTERPIECE season. We are using our new out-of-box LEGO Education SPIKE Prime robot, called Kufar. Have you used such robots? No? Well, let's dive deeper in the construction of out-of-box robots and see how convenient and user-friendly they can be. Take one brick with a couple of sensors and let your imagination run wild as you create the most inventive attachments.
Based on feedback from many of you in this episode I would like to show you how to build an active attachment that changes the orientation of a gear wheel placed vertically to a gear wheel placed horizontally. This attachment could be used in competitions and shows a basic principle of changing the orientation. All attachments could follow the same principle.
In this episode, we introduce a LEGO Mindstorms EV3 version of competition robot construction. It is a modular construction, with medium motor for additional attachments and two light or colour sensors for orientating on the field.
Accomplishing many tasks with a single attachment for the FIRST LEGO League (FLL) 2013 competition. The attachments are using many rubber bands. What is interesting is that it collects/lift/triggers many things at the same time. This is how you could save time and parts during a competition.
Probably the robot I like the most from this series of five robots. See the video to understand why and what is interesting and special about this robot.
In this Episode, we create the next attachment for the box robot two. It is again a pinless attachment, attached to the frame that transfers the motion to a vertical axle.
In this video tutorial, we demonstrate a reusable attachment. It is the same attachment we've previously used for two other missions. Sometimes we can build such attachments - one attachment that can complete several missions. Yes, the mission is similar - it is Load Cargo, but we are loading the cargo in different places on the field, and that's important.
Here is an example of Four(4) active LEGO Mindstorms attachments built-in the frame. Two by two they work asynchronously since all of them are connected to the two separate middle motors of the SUV robot via the frame.
The left attachments work synchronously, and the right attachments are also synchronized couple.
These specific attachments are meant to do nothing in particular, but to serve as an example. Their purpose is to demonstrate different ways in which one could add an attachments to the frame. Experiment. Think and invent better frame with real world attachments that could actually do efficient work and accomplish a mission. Take a video then and share it with us.
This is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.
The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.
In this course, we would like to introduce you to multi-purpose attachments. These are attachments designed to accomplish a number of missions when the robot goes out of the base in the FIRST LEGO League competitions.
You've all seen them. They are kind of large, powered by a few motors and sometimes use rubber bands, levers and other mechanisms.
Use the course as a preseason preparation and try to solve the tasks to prepare for next year competition. Even if you don't have the field, build the attachments and follow the tasks to inspect their behaviour. Modify them as needed when said.
This is the first draft of the course including only the attachments in different sections. If you are interested in learning more please enrol in the course and in the next few weeks we would try to record the video tutorials.
This course is a collection of materials for many of the attachments that we've built at FLLCasts before introducing courses. The videos were built as separate different attachments for different competitions and with the following course, we try to give it a structure.
If you think that the quick pinless attachments shown in video 63 are quick enough, see this tutorial and you will find out that the quick pinless attachments could be even quicker. These attachments can work without motors but by using the inertia forces.
Attachment frames are used on Base Robot Chassis to make it easier to add and remove attachments very fast. This frame is for the Box Robot 1. It is a single module build with LEGO Mindstorms EV3 parts and it could handle attachment on all sides.
We experimented with building a box robot powered entirely by chains—a unique approach inspired by the original LEGO MINDSTORMS NXT Robots. Chains like these can be hard to find, but we thought: why not try to power both the robot and its attachments with them? This design not only powers the entire robot but also provides a great demonstration of how and when chains can be effectively used in robotics.
To build this robot, you'll need approximately 180 chain links (part 3711a), which are available in the NXT kits and some Technic sets.
Please note that this robot requires additional components beyond those included in the LEGO Education SPIKE Prime and SPIKE Essential kits. Check out the additional parts required.
