Tips

  • Use a ruler to ensure straight lines when drawing guidelines.
  • Tape can help hold parts in place while the glue dries.
  • Thinning paint with water creates a translucent effect, showing the cardboard underneath.
  • Varying paint shades (dark and light) creates a three-dimensional look.
  • Draw details on both the front and back for a complete look.

Common Mistakes to Avoid

1. Weak Joints

Reason: Using insufficient glue or tape, or not allowing enough drying time, leads to wobbly or easily broken joints.
Solution: Use plenty of strong adhesive and allow ample drying time before handling.

2. Improper Cardboard Selection

Reason: Using thin or flimsy cardboard results in a robot that is difficult to assemble and prone to bending.
Solution: Choose thicker, more durable cardboard for better structural integrity.

FAQs

What kind of cardboard should I use for my robot?
Use sturdy cardboard boxes that are large enough for your design. Cereal boxes, shoe boxes, or even appliance boxes work well. Avoid cardboard that's too thin or flimsy, as it might not hold its shape.
What materials do I need besides cardboard?
You'll need scissors or a craft knife, tape (masking tape or duct tape works well), glue (hot glue or craft glue), markers or paint to decorate, and any extra embellishments you'd like to add (buttons, bottle caps, straws, etc.).
