It was finally sunny again today after some morning rain!
Today, Chris worked on finishing the design for the Predator/Prey robot and putting it into the Lego Designer. He also looked into ideas for the Predator/Prey activity and the story to go along with it. Reza finished the communication functions for the Predator/Prey robots. He worked on the activity write-up and, with Chris, discussed the storyline and how to work in into the activity.
Brad and Krista made a test model for their non-gyroscopic racing robot today and tested the robot using the line-follower program. They also worked on creating a broad overview of the racing activity. In the afternoon, Krista worked on improving their vehicle model.
Erika and Fara continued to work on the trash collector program today. They made small modules of code to search for objects and to grab objects, and they tested these on the robot. However, they had trouble getting the robot to stop turning immediately when it sees an object during the search, so when it drives forward it always ends up a few centimeters away from the object. They also noticed that the front portion of the robot, which contains the grabbing claws and all three sensors, is too heavy for its minimal attachment to the body of the robot and it bounces around a lot during movement. At the end of the day, they started working on improving the robot's design so it will be more stable when moving and turning.
