Spring 2016 3DoT Goliath Final Project Document

  By: Ayman Aljohani ( Project Manager) Team members: Ayman Aljohani (Project Manager) Tae Lee ( Mission and Systems Engineer) Kevin Moran (Electronics and control Engineer) Jerry Lui (Manufacturing Engineer) Executive Summary Objective The objective of the 3DOT Goliath is to design a small-scaled version of the Goliath Tank, as a toy, that meets the […]

Spring 2016 3DoT Goliath, Body Redesign

By: Jerry Lui (Manufacturing Engineer)   This blog post is to address the redesign of the body to meet the following specific requirements: Print time under 6 hours Scaled model of the Goliath tank Phone and components must fit within the body Sensors must be at a height of 3 inches     To meet […]

Spring 2016 3DOT Goliath, PCB testing

By: Kevin Moran (Electronics and Control Engineer) Once the PCB was assembled by the manufacturing engineer (Jerry Lui), it was to test it. If all the testing and assembling had been done correctly then the PCB should have worked with a problem. As testing began we quickly realized that the PCB was not sending any […]

Spring 2016 3DOT Goliath, SMD Soldering

By: Jerry Lui (Manufacturing Engineer) The reason for this post is to create a guide on how to solder SMD components onto your fabricated board. By the last quarter of the semester, custom PCB’s should have been fabricated and all components on hand. Our PCB is shown above with a total dimension of 1’’x1.425’’. The […]

Spring 2016 3DOT Goliath, Mission Objective Update

By:  Tae Min Lee (System) Mission objective also known as Con Ops was needed to set the rules for the laser tag game.  Both systems engineer from the SpiderBot (Chris Hirunthanakorn) and the Goliath (Tae Min Lee) discussed and finalized the rules for the laser tag game.  The list of rules that are listed below […]

Spring 2016 3DOT Goliath, CDR Debrief

By: Ayman Aljohani (Project Manager) Introduction: Critical Design Review(CDR), is an important phase of the project, it presents the design of the project. It also provides a clear view on the project standing and percent completion. After presenting our CDR, we were debriefed by the president, and the customer on our presentation content . Here […]

Spring 2016 3DOT Goliath, Making Laser Tag Possible: Putting it all Together

By: Kevin Moran (Electronics and Control Engineer), Tae Lee (Systems- Provided the musical notes code needed for this game)   In this post, I will be discussing the final results for the IR Emitter when being used alongside with a Schmitt Trigger and the code that will be used to determine when the 3DoT Rover gets […]

Spring 2016 3DOT Goliath, Making Laser Tag Possible: The emitter

By: Kevin Moran (Electronics and Control Engineer) In this post I will be discussing the IR emitter that is being used to make this game possible, and the components that go along with it:   Components: IR LED: NTE30047 Transistor: 2N2222 Resistors: 8.6k and 110 ohm   The NPN transistor acts like a current regulator […]

Spring 2016 3DOT Goliath, PCB Layout

By: Jerry Lui ( Manufacturing Engineer) The general layout of the PCB was determined by the how sensitive the signal was, the specific wiring of IC’s to surface mounted components, and mounted surface area. Power input was placed away from sensitive signals and had a trace width of 32mm @ 1oz/ft^2 copper thickness (determined by […]

Spring 2016 3DOT Goliath, Making Laser Tag Possible: The Receiver

By: Kevin Moran (Electronics and Control Engineer)     In this post I will be discussing my initial selection for the IR receiver and how I began testing its analog output.   Components:   Transistor: SFH 310 (Opto Semiconductor) Resistor: 2M ohm IR light   The phototransistor is a two legged transistor, with its third […]
