Category Classes with students
Every teacher/instructor can conduct classes with students using these resources. You need to motivate and organize the students. We provide the technical theory, tasks, instructions, programs and everything needed.
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.
Here is another great example of a large multi-purpose attachment used in FIRST LEGO League competitions. This one is specifically for the 2017-2018 Hydrodynamics competitions and is doing a number of missions. (01) Pipe removal, (06) Water Treatment and (08) Manhole cover.
The attachment consists of two parts. The first part is placed on the robot while the second part is in front of the robot and the robot pushes it. While working on the field the robot leaves the second part on the Water Treatment plant and when returning back collects it back and returns to base.
The goal of the attachment is for you to build it and experiment with it with the existing field. Use Box Robot 2 as a robot base on which to add the attachments.

Building instructions for the LEGO Mindstorms EV3 Catapult. The robot has a motor with a clutch and touch sensor to control it for manual loading. The bottom base is removed, so that the Catapult could not be turned around, but that makes the robot small enough to be build in classes with students.

Building instructions for a simple chain tread machine. The robot is actually a simplified version of the Freedom Folk Race tank. All of the ultrasonic sensors are stripped away and the robot can be used for multiple different tasks. The construction is appealing to students and simple enough to be included in a class.

FLL 2017: Attachment To Accomplish The Hydrodynamics Flow (02), Pump Addition (03), Rain (04) And Filter (05) Robot Game Missions
Probably the largest multi-purpose FLL attachment at FLLCasts. These attached is doing a number of missions at once. 4 of them. You attach it to the robot and start the program. The robot moves and accomplishes a number of missions using only this attachment. At it also has a lot of parts. It is quite large and you can not build it from a single set. But that's ok because you are preparing for a competition, right?

Try your hand with this challenge, but be prepared to end it in 5 minutes.

The teacher should first explain the mission to the students: the robot should start from the base, marked in advance, to reach the next line, where the Moon is marked, to go round the Moon and return to the base.
Then the teacher should remind students that they have to accomplish the mission in small steps. Discuss with them what these steps might be.Students’ first task will be to accomplish the mission in which they have a starting and a final point set by the teacher. They should do that by trial and error until they find the correct settings of the robot. It all comes to trying out various settings for power and duration.
The same applies to setting the turn. Students will have to test both the angle and the duration of the turn.
Students should be careful about the sequence of the actions and, most importantly, should find a working solution on their own.
The teacher could make the task more complex: When the robot reaches the dark side of the Moon, it stops, makes a sound resembling the sound from a camera flash and then returns home.
The robot is horizontal. "I took the risk and it turned out great – I put a camera in the self-timer mode on top of the robot. At the start of the program I set a two-second delay, so that we could start the robot and install the camera on top". (Alex)
The teacher should tell students how robots turn in advance. He comments on programming the turn. The most obvious way is to use the tank block. The teacher should also focus on the steering block. You can also use the pictures in the m2 section.
