Robot: Robodyssey ESRA Pheromone Project
Features: Robodyssey ESRA, Basic
Check out The Servo Magazine article
Developers: Students at a local high school

The Challenge: Adding Sexes to Robots?!

To transform 4 ESRA robots into individual beings able to be identified as a young male, old male, young female or old female by an outside observer. No visible modifications could be done to the robots that might hint as to which one is male or female, young or old.

The Solution: They Aren't that Easy!

This exciting challenge was given to a group of high school students as a way to secretly lure them into learning a variety of practical skills. First, the students had to agree on how a robot would behave in proximity to another robot. In other words, how a young male responds to a young female vs. an old female. Secondly, the students had to learn how to manipulate the ESRA's servos to emulate human expressions. Thirdly, the students had to develop a software based communication system to allow robots to identify themselves to the other robots by simply being in the same area. Something we call digital pheromones. Lastly, the students had to tie this all together in code for every combination of associations for each of the 4 robots.
