Mars Mission : Ice Collection Challenge

Mission Brief

You're an astronaut-robotics engineer stationed on Mars Base 7. A massive dust storm has just passed, revealing delicate ice crystals on the red surface. These crystals may hold the key to:

  • Evidence of past or present life
  • Essential water resources for future habitats
  • Fuel production and oxygen for return missions

But there's a problem: the crystals are too fragile to be picked up by normal grabbers. Your mission is to design a rover with a One‑Way Curtain to collect them safely and bring them home.

Step 1: Build the One‑Way Curtain

Create a mechanism that lets ice shards pass into the collection basket—but won’t let them fall out.

  • Use LEGO beams or Axel elements as flaps
  • They should hang from a Pivot Point
  • Attach a STOP bar to prevent the flaps from opening the wrong way.
  • Mount it at the front of your rover
  • Test: make sure objects slide in—but not back out

Step 2: Build Your Rover

Start with a simple SPIKE Prime drive base:

  • 2-motor driving chassis (wheels or treads)
  • One‑Way Curtain in front
  • Collection area big enough for multiple shards

Add sensors, color tiles, or bumpers if you like!


Step 3: Program the Mission

Using SPIKE Prime’s coding interface:

  1. Drive forward to sweep crystals
  2. Turn and repeat to cover the area
  3. Return to the Home Base when done

Tip: Use loop blocks, timers, or sensor-based navigation to make it reliable.


Step 4: Create Ice Shards

Make your own LEGO “ice crystals”:

  • Translucent 1×1 round tiles or slopes
  • Light-blue or clear studs
  • Vary shapes and sizes for more fun

Your Challenge

Build, attach, code, and collect:

MISSION GOALS

  • Design a rover with a One‑Way Curtain
  • Collect at least 5 ice shards
  • Return to Home Base

Document your mission: take photos or videos!
