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.

The goal of this project is to design a low cost BMS (Battery Management System) system that is flexible and modular. The BMS must ensure safe operation of lithium ion batteries by protecting the batteries from: Over temperature, overcharge, overdischarge, and overcurrent all at the cell level. Additionally, the should provide cell balancing to maintain overall pack capacity. Last a BMS should be track SOC(state of charge) and SOH (state of health) of the overall pack.

To meet these goals, we plan to integrate a MCU into each module that will handle measurements and report to the module below it. This allows for reconfiguration of battery’s, module replacements. Currently major companies that offer stackable BMSs don’t offer single cell modularity, require software adjustments and require sense wires to be ran back to the centralized IC. Our proposed solution will be able to remain in the same price range as other centralized solutions by utilizing mass produced general purpose microcontrollers and opto-isolators. This project carries a mix of hardware and software challenges. The software side will consist of communication protocol design, interrupt/sleep cycles, and power management. Hardware will consist of communication level shifting, MCU selection, battery voltage and current monitoring circuits, DC/DC converter all with low power draws and cost.
