Activate the drop attachment with a python program
Program for activating the active attachment using in FIRST LEGO League.
This program is developed for a LEGO Mindstorms Robot Inventor robot and it uses Scratch as a programming language. The program demonstrates the use of a heavy lifting attachment.

In this video tutorial we continue the exploration of pinless attachments and how to add them and remove them in a quick fashion. We've done this for SPIKE Prime and for EV3 and we will provide some other references in the lesson in the course. The idea of an attachment below the robot is that sometime, during FIRST LEGO League competitions we have to bring a mission model from one place of the field to other. Basically push it.
In this video tutorial we demonstrate a Grab attachment build from LEGO Mindstorms Robot Inventor 51515 set. The goal of the grab attachment is to accomplish the mission of bringing loops back to base without loosing or dropping them when returning. The principle of the grab attachment also demonstrates how to have a a locking mechanism. In this way there is not way to the loop to escape.
The video shows why you should not build attachments such as "Crappy Active Attachment For SUV Box Robot". In the video one can see how the knob gear wheels start "jumping", once a force is applied to the lever.
This short animation demonstrates a really useful principle for FIRST LEGO League competition and this is how to use the Inertia of the robot to trigger an attachment that will do the work for us. It is very useful as we don't have to use the motors of the robot and we can afford to use the motors for other things.
This video tutorial is about a detachable attachment. In various FIRST LEGO League competitions there are missions that could be accomplished with an attachment and when you accomplish the mission you must somehow leave the attachment along with the mission model. Probably as a support - most of the time it is as a support. But we've seen some pretty powerful concepts that include things like leaving a clock mechanism that will continue to work for 30 seconds accomplishing the mission.
In this video tutorial we demonstrate an attachment that can accomplish Drop missions. A drop mission is when you have to move on the FIRST LEGO League field with the robot, reach a mission model, and drop a part in this mission model. First time we saw such missions I think was in FLL 2013. The attachment, the robot and the mission model could be build from a single LEGO MINDSTORMS Robot Inventor 51515 set. The mechanism for dropping works by releasing a lever when the attachment is pushed against the mission model. Check them out.
In this video tutorial we look at an active attachment that uses gear wheel and the attachment is general enough to be suitable for reuse. This means that a lot of different missions could be accomplished with the same attachment. The goal of the attachment is to transfer power to a lever through a system of axles and gear wheels. It is interesting that we change the orientation of the gear wheels.
