cooler iii

An application that is used to control the CoolerCoolerCooler

Current Issues

  1. Weight

    • The weight of the current prototype is too heavy for the current motor (even without a loaded cooler). The motor and/or overall weight of the build needs to be optimized.

  2. Precision and Strength of Printed Parts

    • While the printed motor hub connecting the wheel and the motors originally broke from the stress (orig_motor_hub.stl), the new design does not break, but the mounting holes bend causing tilt in the wheels (new_motor_hub.stl).

  3. Functionality

    • Axis Module: Did not provide accurate readings of direction even when tilt was disregarded (level surface).
    • Bluetooth and Application: While the custom application could read from the module, it would not 'write' proper instructions to the device. With that, we were able to determine the location of both the phone and the device, but unable to properly communicate/decode instructions from the app.

GUIDE TO USE

Main Application

The main app features two screens which the user can swipe between

  • Automatic Screen
    • This screen features a map that pins both the user's location and the cooler's location
    • When viewing this screen, control mode will be set to automatic, allowing the cooler to follow the user
  • Manual Screen
    • This screen features a controller UI that is customizable in settings
    • When viewing this screen, control mode will be set to manual, allowing the user to control the cooler If the app has not been bonded, the user will be prompted to scan and connect to a CoolerCoolerCooler BT module (OnStartup)

Bluetooth Connectivity

To connect to the BT module of the cooler, the user will be directed to the Bluetooth Screen which allows the user to scan, connect, and bond the cooler's BT module to the app

  • Bluetooth Screen
    • This screen contains the information of the currently bonded device and an expandable menu that scans for devices
    • If a device is not connected, the app will automatically scan for new devices
    • To connect to a device, the user will simply tap on a desired device's label

Automatic pathfinding

When a user is on the Automatic Screen and the 'Follow-Me' toggle is switched on, the cooler follows the user's GPS signal using a determined pathfinding algorithm to navigate unseen obstacles

Controller UI

To manually control the cooler, the user can swipe or tap to the Manual Screen and use the wheel and slider buttons to control the coolers direction and speed
