FLLCasts Tip

This mission can be completed in a single run from the Blue Home Area. Because the model is very close to home, the robot can drive directly toward it and use the wall to stay straight and precise.

Use a mechanism that slides under the Cane and raises it against the tree as the robot backs away, or with a small rotating motion. The second task is to collect the Support Tie and place it around the Post. A flexible hook can catch the lower part of the Support Tie, lift it, pull it toward the Post, and place it around the Post. Because the chain is short and the action requires precision, an active attachment may make this easier.

You can also split the mission into two separate runs, which may allow much simpler attachments than one mechanism that performs everything.

This mission also has a Seed that can be collected with a basket or fence. Detach it by lifting the red part that connects it to the tree. When the robot finishes working around the model, it can return directly to the Blue Home Area if that is the fastest route.
