Mars Rover: Perseverance (Articulated)

Perseverance - Mars 2020 Rover

Fully Articulated | High-Detail | Scale-Accurate (1:42)

Mars 2020 is a NASA mission that includes the rover Perseverance, the now-grounded small robotic helicopter Ingenuity, and associated delivery systems, as part of the Mars Exploration Program.

Perseverance is investigating an astrobiologically relevant ancient environment on Mars for its surface geological processes and history, and assessing its past habitability, the possibility of past life on Mars, and the potential for preservation of biosignatures within accessible geological materials.

Highlights

Easy to assemble. Great to learn. Click connections and friction fits make it fully and freely articulating, with fewer parts than any other comparable Perseverance model out there (that I know of). 

Meticulously modeled from scratch referencing NASA's 3D models, JPL photos, and documentation, this model mirrors in high detail what the Perseverance Rover on Mars looks like right now.

Design note: On the real Mars rover, the differential bar floats freely, balanced naturally by the rover's 1-ton weight. At this 1:42 scale, light weight and plastic friction can overpower that balance. I engineered a custom "centering spring" (where the real launch lock would be), ensuring the model self-levels and balances on your desk or over any obstacles.

Tolerance Guide

To quickly test tolerances, print 22_Tolerance_Test first.
The test parts should fit easily without falling apart by gravity.

Guide

• Assemble 'from the outside in'. First, assemble Science Arm, Right and Left side of the drivetrain and MastCam, then attach assemblies to the Rover body and connect the rest.

• The Arm parts have more friction than the other links.

• All other rotating links should click in and turn freely with low friction.

• I usually print all upper and lower suspension parts (4) separately with brim and even closer supports.
