The purpose of this project is to design a Bustling Aquacraft Remotely Navigated to Arm COAL (BARNACOAL), a remotely operated watercraft capable of transporting spherical fuel objects (COAL) through a flooded warehouse and depositing them into an aircraft receptacle. The BARNACOAL is controlled by a SPectral Emitter of Commands To Arm COAL (SPECTACOAL), a handheld device operated by a human and equipped with wireless communication, user interfaces for propulsion and dumping, and a physical recharging mechanism. Both the BARNACOAL and SPECTACOAL are built around PIC32 microcontrollers and communicate using a standardized XBee-based protocol developed by a class-wide Communications Committee. During operation, the BARNACOAL must navigate a defined course, avoid alien detection by limiting physical work to charged intervals, and interact seamlessly with any SPECTACOAL to enable coordinated team gameplay. 

SPECTACOAL

• The SPECTACOAL must be capable of pairing with any BARNACOAL

• The SPECTACOAL must have two modes: Drive Mode and Charge Mode

• The SPECTACOAL must contain all controls and displays relevant to propulsion, coal dumping, charge status, recharging, and wireless communication

• The SPECTACOAL must display the remaining level of charge in barnacoal with, at least, a resolution of 1 part in 5

• The SPECTACOAL must incorporate at least 1 analog input and 1 electromechancial output

• The SPECTACOAL must contain a XBee radio module to communicate with a BARNACOAL

BARNACOAL

• BARNACOAL must have a circumference less than or equal to 6 feet

• BARNACOAL shall have a mechanism for carrying/dumping COAL

• BARNACOAL shall display the number of the team with digits at least 15CM tall

• BARNACOAL must track its own charge status

• Once there is zero charge remaining, the BARNACOAL can not perform any work until recharging has occured

• BARNACOAL must have an electromechanical indication of its pairing state
