Packaging Design

Jason HolmesMatt WickesbergMatt GuenetteMichael Piercy

Project Overview

Collaborative effort between the Super Tank senior design team and HKUST team.

Wireless internet communication with vehicles either at Purdue or Hong Kong University to control movement, weaponry, or any extra features.

Tank vehicle on Purdue’s side will provide a video feed to a controller application

PSSCs

An ability to send/receive/decode commands from a controller wirelessly

An ability to control direction/firing capability of a vehicle

An ability to autonomously avoid obstacles encountered by the tank

An ability to provide sensor feedback to a wireless controller

An ability to monitor a battery and prevent signal disconnection due to power loss.

Features and Differences

Self-Contained and Completely wireless Dual Battery slots to avoid shut down

and interruption of vehicle control Larger interior space that both vehicles Extra interior support needed to

improve protection to interior components

Camera is attached to turret, allowing user control of the camera’s direction

Antenna will be contained inside of the tank if wireless hotspot is included.
