Build It

Milestone Worksheet

Checklist

• I listed at least 4 specific, measurable criteria for my robotic arm design.

• I listed at least 4 clear constraints, including physical, material, or budget limitations.

• I drew a simple 2-bar arm sketch showing my design.

• I labeled at least one criterion and one constraint on the sketch.

• I labeled joint angles (θ₁, θ₂) and segment lengths (L₁, L₂).

• I included two positions: rest and active (e.g., reaching).

• I labeled the angles for both positions.

• I marked how far the arm tip moves and the angle swept.

• I estimated the x, y coordinates of the arm tip using sin/cos or triangle ratios.

• I considered how constraints can become criteria with an example.

• I gave an example of how a constraint can lead to innovation.

• I updated my personal Need-to-Know list based on what I’ve learned.
