"FLL Secrets" of the Sharon Mentors team
Dead reckoning on a straight line can accomplish many missions. How many of this seasons missions can be approached in a straight line?
Actually going straight isn't always easy . . .
If you need to turn and go straight as well . . .
Distance is important . . .
Aiming can be a challenge . . .
Modular robot design can help . . .
One way to have more than 5 programs on an RCX - choose to execute one stack of code or another based on a switch being open or closed. A jumper with the ends connected together, placed on a sensor input, will substitute for a closed switch. No jumper shows an an open switch.
Use LEGO pieces on your motor and sensor cables to color code which cable connects where. LEGO pieces with numbers, letters or pictures can also show which direction they show point.
Slower robots can be more precise, but time is valuable.
Try to combine missions that are at the far end of the table ("car pooling" for the long trip).
At the tournament . . .
Mission order is important. Consider your most reliable missions - never let yourself run out of time to perform them. Consider the possibility of reversing scores that you already achieved.
One team member should follow the robot down the field to bring back quickly if it gets lost. Three points is much cheaper than the lost time, and possible field damage that could affect your score.
Bring a cart/table/box to hold the various parts of your robot next to the competition table.
Bring an opaque box, to put the IR tower and the RCX/robot in if program loading is needed.
Bring an extra RCX module, pre-loaded with your programs, to help with battery changes and as a backup if a problem arises with the first RCX.
If your RCX has an AC adapter jack, use an AC adapter when changing batteries, to avoid firmware and program re-loading.
Bring a laptop w/programming software loaded, IR tower, and your robot programs.
If you get into trouble, ask for help! Gracious professionalism means that all sorts of experienced team members will be glad to help you out!
Bring a reference sheet, to remind you of mission/program/module order during competition.
