A wider stereo baseline can improve either-camera coverage while reducing shared sightlines. Compare fixture occlusion, framing and a sideways rig move.

The same roller-follower stroke can need a larger cam to reduce pressure angle. Compare base radius, actual contact geometry and a declared angle target.

Crossing a belt reverses direction and increases ideal wrap, but its spans still intersect. Compare actual tangent geometry before choosing a physical route.

A prescribed gear ratio can hide overlap or missed tooth engagement. Check how shaft spacing changes a fixed involute pair before trusting its animation.

A finite Scotch-yoke pin needs room around its whole rim. A measured Blender study shows how rounded ends and sideways offset change the slot-length requirement.

A measured Blender four-bar study separates full crank rotation, missing assembly angles and a change point where two branches meet.

A measured Blender comparison of equal 40 mm strokes shows why a slider-crank and Scotch yoke offer different near-end windows at constant crank speed.

At a 40 mm transport height, the modeled gripper cleared the sampled path while its cube penetrated the bin. Five Blender runs show why payload geometry changes the height check.

A 120 mm bin admitted the modeled closed gripper but blocked opening before release. Four Blender bin widths show why descent, opening, and withdrawal need separate checks.

A wider gripper opening cleared more sampled approaches in Blender, but an off-center cube still reached one pad first. The 20-condition comparison separates aperture from alignment.
