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.

Featured Project

Our project explored the every-expanding field of drones. We wanted to solve a problem with the dangers of plastic propellers as well as explore new method of propulsion for drones.

Our design uses a centrifugal fan design inspired by Samm Shepard's "This is NOT a Propeller" video where he created a centrifugal fan for a radio controlled plane. We were able to design a fan that has a peak output of 550g per fan that is safe when crashing and when the impeller inside damaged.

The chassis and fans are made of laser-cut polystyrene and is powered using brushless motors typically used for radio-controlled helicopters.

The drone uses an Arduino DUE with a custom shield and a PCB to control the system via Electronic Speed Controllers. The drone also has a feedback loop that will try to level the drone using a MPU6050.

We were able to prove that this method of drone propulsion is possible and is safer than using hard plastic propellers.
