To give you a hint. It is surely something more than 18.75 rotations as we've discussed in the previous videos from the course.

Robot Lifting Attachment With a scissors mechanism

For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.

Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.

Box Robot Two for LEGO Mindstorms Competitions

Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.

English

Here is a task for you. Again, connect your attachment to the robot in this case our attachment to the Box Robot and find the correct value of rotations the number of rotations that you must do so that at the end you have the whole Box Robot attached on the mission model. And this is surely something more than 18.75 rotations.

Courses and lessons with this Tutorial

This Tutorial is used in the following courses and lessons

Improving FLL Robot Game. Course 1 with Animal Allies

The course contains a number of sections with specific examples and tasks on how you could improve your FLL robot game in order to achieve more points. It is designed mostly for after season teams that would like to prepare for next year, but could also work for teams that are currently working on their competition robots.

This course is currently being developed. Sections up to position 9 (without 4) could be used. The rest will be released soon.

Calculate and configure gear ratio

We calculate the number of rotatios when a gear system is involved. The driving wheel will have to do a number of rotations for the driven wheel to rotate to a desired number of degrees. In our specific case when the driven gear wheel is rotate to about 90 degrees the legs will lift the robot.
