Introduction: Free Halloween Headless Robot Papercraft
Say hello to our Halloween papercraft for 2020: the Headless Robot!
• ENTER THE #HEADLESSROBOT I MADE IT CHALLENGE •
Post a photo of your Headless Robot papercraft or Tinkercad halloween background (here on this Instructable as an "I Made It", or on Twitter, or Instagram), and we’ll send you an Instructables giveaway pack! Find all the details of how to participate in Step 13.
• TEACHERS AND PARENTS •
For more details on how to extended this project for additional learning check out further resources in Step 14. Topics include science, stability, center of gravity, and how to balance an object.
- Printed Papercraft (You can download the PDF on the next step.)
- Xacto knife
- Cutting mat
- Pennies or other small weighted objects ( beans, beads, bolts...)
- Rule + Butter knife (Optional - for scoring the fold lines.)
- Glue/tape (Optional - This papercraft assembles with no adhesives, but you can add a little glue/tape to make it sturdier!)
- Cardstock: Use for a stronger more robust papercraft.
- Regular printer/copy paper: regular printer/copy paper is 100% ok to use, but will require a little bit more patience and care when assembling your papercraft so that you don't accidentally squash or rip them.
Step 1: Print + Cut Out the Headless Robot
Attached to this step are four(4) PDF patterns :
- Small Headless Robot in color
- Small Headless Robot in black and white
- Large Headless Robot in color
- Large Headless Robot in black and white
Choose the one you'd like and print out the Headless Robot pattern at 100%. Once it's printed, cut along the outer edge of all of the papercraft pieces.
Step 2: Special Cuts
Once you have cut along the outer edge of all your pieces there are a couple special cuts you need to make:
- Leg tabs: Cut along the black line that runs into the leg.
- Slots: Cut along the inner slot lines with an Xacto knife on a cutting mat. These slot lines are indicated by a thin black line with two dashes on either end. Be careful not to go past the lines when cutting. These line length are well suited for receiving their recipient tabs during assembly. (If you do overshoot them and are having trouble keeping your tabs in the slot - you can use some glue/tape to hold it all together)
Assembly Tips and Tricks:
- Pre-gouging your slots: After you cut your slots, they may be a little tight. I found that by pushing my Xacto knife through the slot, it made it easier to push the tab through it.
- Using your Xacto knife as a guide: If you are having trouble getting you tab into a slot, this can be made easier by putting the Xacto knife into the slot first and then slipping the tab in behind it. Remove the blade and voila your tab is in place!
Step 3: Bonus Credit - Scoring the Papercraft
Scoring your fold lines can make assembling a papercraft so much easier. I used the smooth side of a butter knife to score them and placed a ruler down parallel to the fold line to use as a guide for the scoring. Don't press TOO hard with the butter knife or you may rip the paper.
Step 4: Assembling the Legs
First, roll your leg piece into a tube. Slide the tab into the slot using an angled approach.
Straighten out the leg until the top and bottom looks flush and the tab sits snugly into the slot. Repeat for second leg!
Step 5: Assembling the Head
Fold along the lines and slip the two tabs at the back of the head into their respective slots.
Step 6: Assembling the Arms
Fold the arms in half where the fingertips meet.
There are two arm types to choose from for your Headless Robot. Two are classic and one has a bit of pumpkin stem coming off of it. If you want to build a robot with their pumpkin head ON their body, use the two classic arms. If you'd like build a fully Headless Robot, swap one of the classic arms for the one with the pumpkin stem on it (pictured above).
Step 7: Pre-folding the Torso
Fold along the lines. Fit the front tabs into the sides, then the top tabs. Tuck the back edges inside the torso and insert the last tab on the top of the torso. Doing this here will make assembly much easier later. :)
Now that we've done all our folding and cutting, it's time to assemble the Headless Robot!
Step 8: Attaching the Arms and Legs
Slot the tabs of each arm piece into the two angled slots on the side of the torso. Push the tabs through so the arms lie flat.
Slot the tabs of each leg piece into the two slots located on the bottom of the torso.Push through and make sure they are nice and secure.
Note: If you're worried about the arms and legs staying on, feel free to tape or glue down the flaps on the inside of the Headless Robot :D
Step 9: Attaching the Head
For this step you have two option for where you'd like your pumpkin head to rest:
- For a Papercraft with Head ON:Slot the tabs of the head into the two slots located on the top of the torso. Push through and make sure they are nice and secure.
- For a Papercraft with Head OFF:Slot the steam tab located on the arm piece into the top go the pumpkin head. Push through and make sure it is nice and secure. Tuck in the tabs at the bottom of the head so that they are not showing, or cut them off.
Step 10: Finish Making Your Torso
Slip the two tabs on each side of the torso into their respective slots.
Fold up the back of the torso, and slip the final tab into the neck slot located on the top back of the torso piece.
Step 11: Balancing Your Headless Robot
To make your robot more stable, we need to make sure that most of the mass of the papercraft is above the legs. To do this, re-open the torso and add pennies ( or any other small weighted objects like beans, bolts, beads...) until your robot balances.
