Liz and I looked at more research regarding RF transeivers. We continued to document our research and started building our presentation for Friday. We also continued our lesson plans while building our literature review to be used for our final paper.
We built two NXT “Explorer” robots and programs. The robots randomly search an area and detect and avoid obstacles. It utilizes two different sensors. One is ultrasonic and one is touch. If either sensor determines that the robot is at the end of its current path, the robot stops, looks for the most open path and turns in that direction to continued its most unencumbered movement. To test them, we had a “battle bot” between them to see which would “win”. In a confined environment, they will periodically cross paths and have to avoid each other. On less frequent occasions, they run into each other and avoid each other. Even less frequently, they run into each and get stuck.
Aside from the randomness of the search patterns (which cannot easily be controlled with them at this time), the operation was a great deal of fun!!!
