FLL 2021: Drop precisely - How to accomplish the Load Cargo mission Pro Preview

In this video tutorial we accomplish a mission connected with delivering cargo and it's a drop precise. It's how to accomplish the load cargo mission. We must load the cargo on this train and this is the cargo. We can load it on this train or some other trains. We demonstrate an attachment that loads the cargo into the train and if there is some error there, the attachment auto correct because it will shake a little bit. Let's see. The first thing is to load the attachment. We load the cargo. We load the cargo on the attachment. This way we can move the robot and cargo will not fall. Then we can use some programming to align to the lines to find them moving from base and reaching the mission model. And we align the robot. Now, as we align, the next part of the mission is to drop precisely. And there is a trick here. The goal of this tutorial is to demonstrate the trick. We drop and then we lift the attachment a little bit. So we drop and then we lift. In this way we manage to accomplish the mission and that's a neat trick. Drop and then we lift. This here is attachment. It's not very pinless attachment. It can be removed with one hand but it's connected directly to the motors because we try to have all the attachments built from the same set. Some of the next courses will enter into attachments that are built from more parts and will be completely pinless. That's it. Hope it's helpful and I'll see you in the next tutorial.
