The Jedi CAD Academy

Mission Brief

Your mission, young Padawan, is to design a compound gear train in Onshape that achieves an exact 300:1 reduction ratio under the strict watch of the Jedi Council. Precision, patience, and understanding of the mechanical Force will be key.

Ensure Onshape Account is made with VJTI mail ID for the alliance to access.

Task Description in Detail

  • Design a compound gear train in Onshape.
  • Achieve a 300:1 exact reduction ratio.
  • Use exactly 6 gears in your design.
  • Each gear must have between 5 and 80 teeth.
  • No two gears can have the same number of teeth.

Even if you did not complete the previous mission, fear not — this challenge stands alone and the Force will guide you.


Transmission Blueprint Protocol – Eklavya Mission

  • Rename your holocron (document) to the format:
    Eklavya_<Team Name>_<Team Number>

  • Grant editing access to the Jedi Council members:
    [email protected]
    [email protected]
    Do this once your design is ready for review and inform your mentor.

  • Blueprint requirements:

    • Label all key components clearly:
      • Input Gear
      • Output Gear
      • Input Shaft
      • Output Shaft
    • Include a marker to track revolutions.
    • Ensure the design is clear and easy to evaluate.

Clarity, precision, and compact design will lead your squad to triumph.

Expected Outcome

  • Onshape design file (Link to the File with edit Access)
  • Animated GIF of the working mechanism
