ROVER-X

A STEM PROJECT

Modeled after the Sawppy Rover by Roger. Thank you https://hackaday.io/rogerrandom

ROVER-X will be used at a School Assembly Program, and will be fitted with Instruments and Equipment to engage students in STEM related activities.

  • 3D-Printed Parts

    My first assignment was to print the 3D needed parts. I used my Prusa MK3s and Red and Black PLA.

    I printed almost all the parts from the .stl files posted by Roger. What I did different was that I printed 4 components from the STL's edited by Laura (CJ Rover) to accommodate enforced mounting, while also printing two components at 100% infill for Strength. Other than that; I printed the Knuckles mirrored to place the motors in symmetry, and at some point in the future I will be printing 3 wheels mirrored because unlike on the real curiosity rover our wheels have directional spokes. I did not print the Battery Tray or the Power Tray; I will print those trays when I decide where to mount the parts later.

    Special thanks to Roger and to Laura for guidance.

    COSTS

    * 3D-Print the Parts Yourself $100

    I used less than 1KG of Black PLA for Wheels, and less than 2KG of Red PLA for all other parts. I Paid $75 on eBay for all 3KG Shipped, and my Printer used about $20 worth of Electricity. If you have a 3D Printer with suitable size bed you should be looking about the same of what it cost me.

    * Have someone 3D Print them for you $600

    Don't have a 3D-Printer? Don't want to learn the Slicer software? or deal with 2 Weeks of printing? I found a few places online, and this one seems reputable https://print.all3dp.com/ so I uploaded all the parts and the total was $600 for the Entire Set; Tax and Shipping Included.  I suppose you just have to instruct them which parts you want mirrored along the x-axis, and about the infill factor being 30%.

  • Raspberry Pi 4B

    Ameer04/25/2020 at 16:53 0 comments

    I decided to use the newest Raspberry Pi model; the 4 B.

    It can be powered via the USB-C port, and it uses a Micro-HDMI to output display. You will also need an 8GB Micro SD Card (or 16 or 32; I chose a 16GB), and an SD Card Sleeve for it.

    https://www.raspberrypi.org/downloads/

    Download The firmware Raspbian onto your PC, download Installer onto your PC as well, then run Installer and choose Raspbian as the firmware and the Micro SD Card as the place to install its image.

    NOTE: If you buy a Pi4-B make sure you get the HDMI- Micro-HDMI Chord, and a USB-USB-C Chord for it, and a Gen 10, micro SD card  & SD Sleeve.  You will need a USB Keyboard and a USB Mouse later to use your Pi.
