FLL Stratagy – some easy targets

Easier missions are the missions that are closest to the base and with the larger targets. Attachments can make the hard targets easy as well as well as using sensors and lines or the wall to make missions close. For instance bowling, the robot can move all the way down the field, hit the wall with a touch sensor and then you know you’re near the bowling lanes.

The large video screen is the closest to base should be a fairly easy task to do. The easiest way to manipulate this is to push down the handle but to do that the robot needs to move out of the base, turn, and use some type of manipulator that pushes down the arm as it moves over it. Some other ways to manipulate the arm are:

  • reach over the screen and push the arm down
  • push up the flag
  • Or probably the easiest, go around the screen and pull the handle down.

Another fairly easy target is the blue quilts. All the robot needs to do is to push the two blue quilt squares from the base to the other two blue squares. It’s not quite a straight shot so the robot would have to push the squares out, turn slightly and push the squares to touch the black scoring area’s next to the other blue squares. Something will need to keep the squares from sliding to the side when a turn is made.

The “chair back to the base” portion of the wood working mission. should be somewhat easy. The goal is to move out grab the chair and bring it back to base. The trick is to have an attachment to grab the chair. One way may be to have a latch go across the where it would pull the chair back. Another way would be to have a hook of some type loop the chair and pull it back.

These are just a few of the strategies to get you started. You still need to do the programming and build the attachments.

Good Luck. If you have any questions, please e-mail me.
