How We Built Our Robot

Very Stiff and Stable Frame 
Uniform Magnetic Tool Attachment 
Pins for Stabilizing Attachments
Sensors - 2 Touch, 2 Light,      2 Rotation
Weight Over the Wheels
Guard for Wheels
Big Wheels for Speed
Worm Gear on Arm for Strength and to Hold Position
Double Universal Joints for Worm Gear
Tools Needing Most Strength Permanently Attached to Robot

Navigation and Movement

Precise & Standard Starting Locations 
Robot Lines Itself Up at Beginning of Each Mission
Move Blocks for Automatic 2 Motor Synchronization
For Accuracy
Always Start Square to Wall
Straight Lines
Pivot Turns
Rotation Sensors
Realign Mid-Course With Light and Touch Sensors 
Alignment Jig for Inside Rainbow Run

Programming

  • One Master Program
  • Mission My Blocks
  • MiniBlocks to Save Space
  • 1 Count Loops to Synchronize Threads
  • Used Loops in MyBlocks to Backup to Walls and Line Up to Lines
  • One Button Push to Get to the Next Mission
  • For Mission Flexibility:
  • o Left Button Repeats Last Mission
  • o Center Button Executes Current Mission
  • o Right Button Skips to Next Mission 
  • We Used Variables to Store Which Button is Pushed
  • We Added Display Blocks to Our Mission Control Program so that Our Robot Can Tell Us Which Mission It Is Ready to Run Next
  • Our Results are Extremely Predictable Because We Use Light, Touch, and Rotation Sensors to Accurately Find Our Position
  • We Calibrate Our Light Sensors to Adapt to the Lighting of Each Different Field
  • Robot Decides Whether to Stop in Yellow or Go to Research Station, Depending How Much Time is Left
