Gather round and follow this here Instructable to transform your iRobot Create into your very own personal WiFi scanner and optimizer! What the iRobot Create will do is find the best WiFi signal in a given area or room based on discrete sample relative to the iRobot's starting position.
Here's what you need for this project:
~The one used in this project has five LEDs, four green displaying signal strength when signal is available, and one red when no signal is found
- Soldering Iron
- Flux/Soldering Paste
What it does:
- Takes in WiFi data from four spots, North (up), West (left), South (down), and East (right).
- Analyzes data, moves towards best wireless direction.
- Continues to get WiFi data and move towards the best direction.
When the data is found, beeps are transmitted for the signal strength. That is, 1 beep for 1 bar strength, 2 beeps for 2 bars, etc. The beeps also move up octaves for each level of signal. The iRobot will continue its algorithm to infinity, and is based around the gradient descent algorithm.
