David's Progress on the Egghunt Project
Date: Fri. 01/04/08
Completed:
- Rough plan for the entire egg hunt.
- Countdown to automatically stop the Create from running after 2 minutes time limit.
- Coded for basic trajectories and random movement to find eggs (by rotating or spiraling while detecting for certain egg color) and deliver it to the goal.
- Coded for evasive maneuver from walls and opposing Create bot (possibly using the distance sensor to evade before collision take place), but for now something similar to wimp mode using bumpers.
Trouble with:
- Detecting egg and verifying the distance needed to drive then stop to pick up the egg.
- Deciding whether to pick up the egg and drop it at the goal or dragging it and push it into the goal.
- Not sure how to detect an egg color and its distance at the same time.
- Not sure how to code to drive to retrieve the egg. and light sensors reading may read different values on same colors due to brightness or distance.
Need to:
- Find out how many of each sensors will be needed to be maximize effectiveness in egg hunting and where their positions should be in order to find out reading values for coding.
- Building the a rig powered by servo motor and code it to pick up and drop egg.
- Considering to incorporate "P.I.D" control to the Create's driving while hunting for egg to ensure accuracy and safety of the Create.
- Finally try to combine everything and code for an egg hunter GUNDAM 0X08.
Ideas:
- Thinking about dragging the eggs into the goal by pushing it may speed up the process.
- Placing distance sensor and light sensor together may help detecting distance and color of a single egg at the same time.
Date: Fri. 01/11/07
Completed:
- All the planning is completed (the outline for the entire egg hunt)
- Built an efficient "grabber" to grab an egg then drop it off at goal.
- Understood how to code for servo motor.
- Coded for how the Create goes about to finding the egg (similar to wimp mode).
- Quite sure one which external sensors to use on different tasks like detecting egg, light, and other objects.
Trouble with:
- Incorporating P.I.D control into programming the Create.
- Still in the process of figuring out the most efficient pathway the create should take in order to find egg and drop it as soon as possible.
Need to:
- Find most efficient way possible for the Create to retrieve and drop off egg.
- Need to finalize on how the servo motors should be programmed in order to pick up an drop off the egg.
- Need to find out whether wimp, following the wall, or Braitenberg concepts should be use to find the egg.
- Put all the finished pieces together and modified as needed to program the Create for egg hunting.
