Description  Demonstrate advanced control of the iRobot Create  Use light sensors to guide the robot to a light source  Read bump sensors and continue accordingly More complex than Lego Mindstorm

Solution  Send data back for debugging  Read appropriate light sensor data  Design of hardware  Detect bumps  Run trials to fine-tune algorithm

Exceptions  Contrast is your friend  Speed was not considered  Additional sensing to aid in search

Methodology  Small steps  Frequent trials  Troubleshoot big ideas with small advances  Modules!  Get to know manuals Hardware  Vs.

Diagrams

Demonstration – Following Light

Demo- Detecting Bumps

My Strategies  Manuals most trusted  PAC was my work area  Regular meetings with professors  Talk through difficulties with peers

Concepts  Programming Languages Understanding similarities  Data Structures Types, type casting  Assembly Language Working directly with processor Complex commands Bitwise operations

Extensions  Adding additional hardware  Reading additional sensors  Communication between robots

Advice  Write trusted code  Don’t second guess yourself  Weekly talks with Professors  Update journal weekly- minimum
