  1. There are no double or triple pins protruding from the parts that they connect;
  2. The motors are attached to the robot on at least two points. The points where the motor can be attached at are below, above and behind;
  3. There are no axles bearing weight. Axles have the sole utility of translating or preventing motion of parts. Axles are NOT used for attaching sensors or other constructions.
  4. Do not use light grip pins on constructions that are not meant to spin.
  5. Shake the robot up a bit. No part of it should wiggle in any way.
