Overall Robot Dimensional Restraints
- Robot Perimeter = 28" x 31 3/4" (119.5 total length)
- Top of Drive Base: 4.6" (1.6" clearance)
- Top of bumpers = 6.5" (1.5" clearance) - note 6.375 (1.0375) is better for intake if it does not cause problems clearing rendezvous (1.0625" high steel tube).
- Extension of Intake = Approximately 10"
- Clearance at front of robot for intake = 3"
Hang mechanism in starting position is below shooter wheel- Please allow minimum .5" to edge of frame perimeter unless design actualy requires less to work/fit.
