Sub-team | Item | Description (purpose/what it does, product link) | Cost (incl. unit cost and quantity) | Estimated lifespan | Implementations schedule (when will we start using it) | |
|---|---|---|---|---|---|---|
Autonomy | Jetson Nano (moving to MEF?) | Computer that allows us to run our airside system on the drone. It’s good because it provides the necessary hardware for us to run our airside system and LTE telemetry. NVIDIA Jetson Nano Developer Kit (945-13450-0000-100) : Amazon.ca: Electronics | $279.09 x 2 = $558.18 | Lifetime | Next Comp Cycle | |
LTE Hat (moving to MEF?) | Board to allow Jetson Nano to connect to LTE networks. 4G/3G/2G/GNSS Expansion Board for Jetson Nano, Based on SIM7600G-H, Global Applicable (waveshare.com) | $76.99 x 2 = $153.98 | Lifetime | |||
Laptop with GPU | Computer with GPU to allow the airside system to run on the ground and also serve as the ground station computer. ASUS ROG Strix G15 (2022) Gaming Laptop, 15.6” 165Hz IPS Type WQHD Display, NVIDIA GeForce RTX 3060, AMD Ryzen 7 6800H, 16GB DDR5, 1TB PCIe SSD, RGB Keyboard, Windows 11 Home, G513RM-AS71-CA : Amazon.ca: Electronics | $1679.00 | Lifetime | |||
Electrical (Category description) | PCBs + Wire Strippers | WARG custom designed PCB fabrications and electrical components on the PCB; Off the shelf high current (Electronic Speed Controller) PCBs; Wire stripper + cutter 2 in 1 | ||||
Electrical | Wire Stripper | Strips the insulation of wires. 10awg-28awg | Max $20x5 = $100 Min $20x2 = $40 tax included | Lifetime until they dull (at least 5 years) | As soon as possible | |
PCB manufacturing | PCB manufacturing and electronic components on PCB Price is based on our previous orders. For example, Lighting + 12S Servo Module PCBs + electronic components cost around $500. Each project cost $250, there are around 10 projects active at the moment, all of them might be ordered in the next 12-18 months see all components for the 2 projects listed in this digikey cart | Max all 10 PCBs → $2500 Min 5 PCBs → $1250 tax included | Lifetime (15 years) | - | ||
Obsolete Hardware | Upgrading damaged or old drone electronics (e.g. ESCs) 12S ESC 80A x 4 or 12S ESC 60A x 4 | Max $640, Min $500 (i included 13% tax) without tax is Max $560, Min $440 | Lifetime (15 years) | - | ||
Embedded Flight Software | GPS Sensor | Absolutly crucial sensor on every drone. It help tracks the position of the drone, so more high level control algorithm can be applied to make it fly better. Tracking antenna also needs GPS, since the rationale behind tracking antenna is pointing the head of the antenna with knowing the relative GPS position of the tower and the drone | With unit price of 40$ each (actual price can vary 30 ~ 100 depending on quality and market), we would like to request for 4 or 5 more GPSs https://rotorvillage.ca/foxeer-m10-q250-gps/ or https://holybro.com/collections/gps/products/nano-m8-5883-gps-module or RTK GPS(good ones): | 5 years (not quite sure) | As soon as we get the funding | |
IMU Sensor | The even more crucial sensor on a drone than GPS. It tells you the acceleration of motion, rotational motion, etc to help the drone to maintain its proper attitude. Use in both our custome flight control software Zeropilot and Tracking Antenna | 40 $ each, need 5 more | 5 years | As soon as we get the funding | ||
GPS Antenna | The RTK GPS could get a stronger signal with is antenna module | 2 * 75$ | 5 years | As soon as the GPSs arrived | ||
XBees (or see if we can find any replacement of that) | Wireless communication module for delivery drone telemetry radio wirelessly | 4 * 50$ | 10 years | The sooner the better | ||
Testing Fixed Wing Plane | Made up by foam as body + wing bar + servos + motor + propller + metal sticks We need to make more/maintain | 200 $ | uhhh (it might just disappear in one filght test) | Before we finished our milestone 2 in our flight controller software (probably this term) | ||
STM32 Nucleo | This type of microcontroller had always been used for the WARG flight controller. And we constently need to procure more as we are having more testing going and some of the board are damaged | 5 * 30$ | 10 years | After midterms | ||
Arduino | Arduino is used currently on the tracking antenna to do all the computation. More of the arduino might be used later for the ground station and testing system | 3 * 40$ | 10 years | Not very urgent since we still have stock, but will be needed in this year | ||
Radiomaster Ranger | A telemetry/control radio transmitter. One of the favorite telemtry delivery solutions in the team. We only had one before, would very nice if we don’t have to flight for it, and have our own in EFS. Its also a lot cheaper than RFD900 that is also telemetry transmitter but 700$ for a pair | 150$ before tax and delivery fee | 10 years | Will be used immediately after getting it | ||
Radio receiver | Receives the controller radio. Have to have them to fly a drone. | 4 * $30 | 5 years | Will be used immediately | ||
Mechanical | Airframe Manufacturing | Carbon fibre, foam, aluminum stock, fasteners, wood, servos, misc hardware | $1500 - Carbon fibre raw material and tubes for continuing competition drone program $750 - Foam, hardware, servos, and wood for new fixed-wing design | Comp drone to be used for another competition cycle, ~1.5yr Fixed wing to be used for ~next 2 terms | Comp drone funding to be used as soon as funds are acquired, throughout entirety of next term Fixed wing to be used during S24 | |
