Linda's Progress on the Egghunt Project
Date: Fri. Jan. 4. 2007
Completed:
- Distance sensor is insensitive to color: use light sensors to detect egg color. One light sensor is slightly more sensitive than the other (30-50 difference): calibrating may or may not be neccessary.
- Set up "Blue Egg Mode" and "Yellow Egg Mode" based on the "Pause/Resume" code from Lab 5 Braitenberg.
- Coded function to make speed proportional to light values sensed.
Trouble with:
- Coding the initial search for the light: coding the Create to run around looking for a light value that's greater than the ambience.
- Applying revolutions to increase drive radius when spiraling (use wimp mode instead?)
Need to:
- Figure out how to calibrate the color-detecting sensors if neccessary (Blue/Yellow differentiation)
- Finish Braitenberg Lab (photophilic portion): alter codes for "finding goal" portion of egg hunt.
- Code spiraling random movement for egg search, or alter Wimp Mode. (But once the egg is found, drive straight?)
- Apply 2 minute timer to "Blue/Yellow Egg Modes."
- Extend light sensor wires to be able to position them infront/on sides of Gundam at "egg-level" to detect the eggs. (Gundam is too tall!)
- Experiment with straw length and positioning of light to the sensors: figure out best straw length and positioning of light sensors on Gundam (pointed straight ahead or pointed in, etc) to cover entire front range.
Ideas:
- How to position the light sensors to be used as egg-detector, goal-finder, AND color-confirmer (sense color of egg before captured, or when captured in rig?). Place distance sensors directly below light sensors (need 2 long(?) distance sensors?).
Date: Fri. Jan. 11. 2007
Completed:
- Coded two-minute Timer.
- Coded proportional drive towards the light/goal and stop.
- Worked with David to design and build an egg-capturing rig (removed the back of Gundam).
Trouble with:
- Getting Gundam to take actions after having stored the highest value when returning to the goal.
Need to:
- Alter codes for Lab 5 Braitenberg's initial search to be used as random search for Blue/Yellow Eggs.
- Alter Braitenberg codes to have Gundam search for Blue/Yellow eggs instead of the brightest light source.
- Figure out how to calibrate the color-detecting sensors if neccessary (Blue/Yellow differentiation)
- Extend sensor's wires?
- Experiment with straw length and positioning of light to the sensors?
Ideas:
- With egg-capturing rig in the back, maybe have Gundam reverse-oriented to make light sensors muilti-purposed? or just add another light sensor?
