A spinning platform will be assembled on the moving robot. A ultrasonic sensor would be mount on top of the platform. The ultrasonic sensor will get the distance between the current robot to the surrounding objects and transfer it's own distance data to an arduino board. The arduino board will convert the data to become the format that a smart phone can process. Then, the processed information would be sent to a smart phone.

Then we want to connect our mapping system to a robotic programming platform called starL.
StarL can use a smartphone paired with a robot(irobot create) using Bluetooth and control it's movement. It is also capable of communication between robots.
After we have a self mapping system connected with starL, we would like to make it distributed, which means a number of robots working together to map some space. We are going to combine the distance information generated from each individual robot. By knowing the start position of every robot, this enables the robots to know the relative position to each other.

This project would require a power source, a circuit that helps control the motor, some sensor data filtering circuit, one motor for the spinning platform, C coding on arduino to process sensor data, java coding on android phone. We may need to add a circuit that helps transfer data from arduino to the phone.

Problem Statement:

Radio frequency interference from cell phones disrupts measurements at the radio observatory in Arecibo, Puerto Rico. Many visitors do not comply when asked to turn their phones off or put them in airplane mode.


We are planning to design a handheld device that will be able to detect radio frequency interference from cell phones from approximately one meter away. This will allow someone to determine if a phone has been turned off or is in airplane mode.

The device will feature an RF front end consisting of antennas, filters, and matching networks. Multiple receiver chains may be used for different bands if necessary. They will feed into a detection circuit that will determine if the power within a given band is above a certain threshold. This information will be sent to a microcontroller that will provide visual/audible user feedback.
