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 […]
By: Kevin Moran (Electronics and Control Engineer) For Fall 2016’s 3DoT Goliath it was my job to design from scratch a printed circuit board that would allow our rover to emit and IR signal, and also process a receiving signal. This process started as a messy image on my notebook, and was later processed […]
By: Kevin Moran (Electronics and Control Engineer) One of the things I mentioned in the previous posts, was that by using an IR emitter (LED), the range was very limited. Testing showed an average range of 3-6 inches. In order to have a reasonable range for the emitter, it was necessary to concentrate […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
