@description Building the cardboard inchworm

~avatar avatar

Turn a piece of cardboard into an inchworm!

~

Duration: ~45 minutes

Materials

  • Cardboard
  • Scissors or cutters
  • glue gun or tape
  • 1 paper clip

Step 1: cardboard

Cutout a cardboard rectangle. You can use the @boardname@ as a ruler to figure out the size.

Step 2: center fold

Fold the cardboard in half over the short edge.

Step 3: legs

Fold each end so they rest flat on the ground.

Step 4: front teeth

Fold each corners on one end of the cardbard. This will be the front of the inchworm which is supposed to grip the ground.

Step 5: back teeth

Using a scissor or a cutter (watch the fingers!), cut out various strips in the other edge. Fold one after the other.

Step 6: mounting the board

Using tape or a glue gun, mount the @boardname@ on one side and the microservo on the cardobard.

Step 7: mounting the servo

Attach the servo on the edge of the other cardboard side.

Step 8: Cable clean up (optional)

Use tape to route the cables nicely on the inchworm.

Step 9: attaching paper clip to servo

Unfold a paper clip and attach it to the servo arm.

Step 10: attaching paper clip to cardboard

Slide the folder paper clip into the cardboard, and use tape to secure it. You might need to toy around with the size of the clip so that the servo rotation opens the inchworm sufficiently.

Step 11: it's ready!

Your inchworm is ready!
