All projects related to physical movement or that include moving elements will be eligible. We’d love to see all kinds of machines, robotics, mechanical creations, simple non-electronic machines like automata, and so on.

Make a real-life physical object that you designed using Tinkercad, and you’ll be eligible for the special judges prize!

Judging Process – The winner(s) will be determined through two (2) rounds of judging, as described below:

Selection of Finalists – In the first round, Judges from the Sponsor’s Instructables staff will rank each eligible entry on the basis of a composite score based on the Criteria, assigning equal weight to each of the Criteria. The entries with the highest scores will qualify as finalists, and the number of finalists selected will be as identified in Section A above.

Selection of Winner(s) – In the second round, the Judges will apply the Criteria to evaluate the finalists, using a range voting method, assigning a value between 0-9 to each finalist. The finalist(s) with the highest score(s) will be selected as the winner(s), and the number and type of winners will be as identified in Section A above. Any ties will be broken using the median ballot rating approach (the entry with the highest median score wins).

Disqualification –  The Judges have the right to disqualify any entry that is not in compliance with these Rules. In the event that a winning entry is disqualified, the next-highest scoring entry will be selected as the alternate winner. In the event that one or more of the identified Judges is unavailable, Sponsor reserves the right to substitute Judges of comparable qualification, to be determined by Sponsor in its discretion.

The Contest is entirely skill-based and contains no elements based on chance. The standards applied during the judging process focuses on assessing each entry’s properties. By the mere submission of an entry, an entrant acquires no automatic right to be awarded a prize, nor any other right except for the right to have such entry reviewed and evaluated subject to these Rules.
