We want to build a robot that can handle orders & deliver food in restaurants. Patrons would have a alert mechanism (button) to call the waiter (our robot). Our kitchen would have internal transmission network (between robot, kitchen and tables) that would receive this request and then the robot would be dispatched to assist the customer. Patrons would also be able to place orders using the robot (LED screen). The restaurant staff would also be notified of the various orders which they would dispatch through the robot later on.

For the navigation, we have talked to a TA and the machine shop for advice. The TA suggested for this one-semester project, we could use fixed locations for our tables and map that to the micro-controller on the robot to program it on where to go. Greg from the machine shop also helped us suggest what wheels, motors could be used to build the robot. Currently, we are looking at a 4 wheel with 2 wheels that are driving the movement and 2 that are just following (they help support the load on the robot). We also talked with Greg on how to get the distance moved by the robot. He recommended that we can calculate the distance moved using data from the encoders that are attached to the wheels of our robot.

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.

Description:

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.
