MananEggHunt

Back to Main

• January 11, 2008
  • Created the unrefined code for an advanced search pattern and tested it on the robot. It essentially scans left and right for the closest object every second (using sensor on a servo), and then goes towards it. Still needs to be modified for egg hunt, but currently works as a soccerbot.
  • Attached the claw (capturing device) to the rear end of the robot.
  • Created functions to move the arm up and down (to capture ball).
  • Figured out ideal values for distance and color detection.

• January 4, 2008
  • I've modified wall following to get a certain distance away from an object/wall and then stop.
  • I've taken rough estimates of the sensor readings of blue and yellow eggs. However, I didn't record the distance away from the object, so next class I'll create a formal study to see the ideal distance away from the egg and average sensor readings of the colors.
  • I've created a "rotating eye" on the create using a servo and a IR distance sensor. The servo rotates the sensor left and right so that the Create can look for objects that aren't necessarily right in front of it. Essentially, its like having the ability to turn your head left and right, rather than being forced to turn your body every time you wanted to look to the right or left.
  • I'm going to create a table that converts the IR distance sensor values into actual units in terms of inches. With this, we can simply specify how far in inches our robot should be away from the egg, without needing to tamper directly with IR values.
  • I spent approximately 5 hours over vacation testing the servos and setting up the rotating eye code, as well as another 2 hours outside of class over the past week testing the light sensors.
