ProgressCheckEgg Hunt Ideas progress made January 4 Determined that the best way to detect the color of the egg was to use light sensors Gathered the data of these two colors. The range of values for the blue egg was from 100-130 The range of values for the yellow egg was from 160-210 Determined that light sensors were not efficient at finding the egg The detection range was about 5 inches: too small to use as a locator We decided that distance sensors are accurate at finding the egg The larger distance sensor would detect an egg from about a foot away Once this egg was detected, the robot would go towards it Decided that instead of having a crane to capture the egg we would use a "trapping device" one that would capture the egg in a basket and keep is secure while the robot is driving to the end point to drop it in progress being made over Thursday and Friday Chris has the robot on Wed and Thrusday to finish the light sensor code that will allow the robot to be guided by the Christmas lights around the end basket. Casey will be searching for materials to make the basket to trap the egg in (servo motor will be used to maneuver this basket) Casey will have the robot over the weekend (or once Chris has completed the light following code) to start testing ways to locate the egg Should the robot spin out until the distance sensor located an egg? Or perhaps it should drive straight while turning from side to side to locate an egg? Meanwhile, over the weekend Chris will be learning how to use the servo motor to move the basket to trap the egg. progress made January 11 We have decided that the best way to search for the eggs are to use an altered version of a wimp mode. We will alter this wimp mode so that is does not stop after 60 cm and will drive in a random pattern, not in a straight line This wimp mode and portion of the egg hunt challenge was completed the previous tuesday We have decided to use a basket like structure to trap the egg of the correct color Brainstorming and contruction has begun on this structure and will be completed over the weekend. We have decided to place the basket on the back end of the robot The light following and wall following portions of the project have been completed and are ready to be used in the egg hunt competition Casey has finished the loop that will run the robot for two minutes Progress over the weekend Casey will be programing the random pattern driving and locating an egg Chris will be finishing the contruction on the basket, and using light sensors to distinguish an egg.
