THe carabiner is for picking up the loop on the south wall. The first version didn't have enough space for loops that were slightly different. It also stuck out too far to be able to do the Cloud Access mission in the same run. It got shortened, a thinner axle for the "gate" part, and made taller to increase the margin for error.We use the wall follower in our Engagement Zone. We use the drift steer to keep it against the south wall. It drops into the robot and pulls right off. Very easy to attach and remove. The pulley wheels that follow the wall come off sumetimes. Thinking that we should make the axles that hold them longer? Also, it wouldn't work if the table has short sides. Maybe we need to make it extend down lower too just in case.
This is our first attachment. It started as a stick of short technic beams and we were using it to open the door. It didn't always move the same way. So we changed the programming so the set up was always laying flat against the brick. This made it move the same way everytime no matter who ran the mission. Then we realized the door wasn't always exactly the same. So we added a bendy stick at the end so it was flexible. This made it more repeatable. We also figured out a way to add a loop to carry the ball. Planning to use this to make a shot toward the goal.
