# FLL 2018: How to accomplish M06 (precisely push) from FIRST LEGO League 2018 Into Orbit. Review ProPreview

This video tutorial contains a details explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M06. SPACE STATION MODULES. This again is a very interesting mission from the competition from which we could learn a lot of basic principles in the field of robotics.

## Align to the mission model

Aligning with the mission model for this specific mission is extremely important and makes accomplishing the mission quite easy. The programing is really basic. Just move forward, but while moving forward we hav ea special attachment with two guiding beams that guide the whole robot to align with the mission model. From them on it is extremely easy to accomplish the mission.

## Initial considerations

When initially thinking about the attachment we were discussing some ideas show below. They could help you understand the process of coming up with such construction.

To align the attachment precisely and properly, like in this mission you have to following some rules:

1. The attachment must move freely in relation to the robot when it is in contact with the mission model. To achieve this the attachment must not be rigidly connected to the robot. Probably the easiest way is to make the attachment pinless. You can attach it to the robot wit a hook on some big hole in the robot.

2. The attachment must get in contact with the mission model if possible. If this is not possible the attachment needs to be in a contact with something else to be sure that it is oriented/aligned properly and on the right location that is accurate enough.

3. There might be large friction between the mission model and the element that needs to be mounted to the model. If the rules do not allow you to actively control the attachment around the mission model or if this will interfere with the proper movement of the robot, you have to create detaching mechanism inside the attachment to detach the element from attachment.
