Scoutbotics 3

Scoutbotics 3

 

On Saturday, March 25th, 2017 Zagros Robotics teamed up with The Greater St. Louis Area Council of the Boy Scouts of America for our third Scoutbotics Event. Zagros Robotics created a custom robot starter kit for the participants. This event was again held at St. Louis University. 43 Scouts earned their Robotics Merit Badge while 9 returning Scouts perfected their programming skills to earn the Programming Merit Badge.

Competition Path 

 

For the first-timers, the day began learning about Robotics as a career and then they quickly dove into building and wiring the robots. For returning Scouts, the discussion immediately centered on writing code and determining robot capability to address different challenges.

Preparing the Robots

  

This time the Scouts had access to a new Gobbit Line Command library in the Arduino IDE created by Primal Engineering. The Gobbit Command Line library greatly simplifies the C/C++ syntax that the Scouts need to understand for the line follower program. Both groups perfected their programs by testing and tweaking in preparation for the timed competition!

Running the Path

 

The complexity of the line-following solution was the defining difference between those new to Scoutbotics and the returning Scouts. Both groups had the same line-following path to solve; the robot started at one side, had to negotiate the line to the opposite corner and return to the original position. The beginner group had to improve the example code to create a more efficient path through the course. The advanced league was given additional programming knowledge which allowed for more innovative options for completing the challenge. The truly advanced solution involved having the robot leave the line, cross the open space and then re-engaging later to complete the course:

 

Off-Line Solution

 

Each Scout had the opportunity to tweak their program during competition as well. Multiple rounds offered the chance to improve performance as the competition progressed.

Tweaking between Trials

 

The competitors at each level with the fastest robots were declared the winners of Scoutbotics 3 and received overlays for their robots displaying their achievements.
