Orange Kayak

This is the autonomous kayak in Singapore that will be instrumented with pressure sensors similar to Big Red.

Experiments to conduct, summer 2011

Purpose
- Detection of flow separation at bow
- Detection of helical vortex
  - This is less important and won't be addressed this summer
- Drag reduction during maneuvers
- Characterization of pressure field in real operating conditions
Experiments to perform
- still water tests
  - characterize pressure change across the bow for circular maneuvers at different speeds and circle radii
  - could be done in Pandan Reservoir
- tow tests
  - at NUS pool?
  - reproduce Big Red constant angle of attack experiments
- ocean trials
  - piggy back on the sea trials
  - straight line motion in area with oblique current
  - lawn mower waypoint navigation
  - straight line motion with waves and no current
Beyond Summer 2011
- pressure feedback control of thruster for smart maneuvers
- separation control?
- object detection
