Amigurumi Robot Crochet Free Pattern

If you’ve ever wanted to add a little mechanical charm to your crochet collection, this amigurumi robot free pattern is exactly what you’ve been looking for. Robots have a timeless, universal appeal — kids adore them, collectors treasure them, and makers love how their boxy, geometric shapes translate beautifully into crochet. Whether you’re making one as a gift, a nursery decoration, or simply because you enjoy the craft, this pattern will guide you from your very first stitch to a finished little robot friend you’ll be proud to display.

This is a beginner-friendly to intermediate pattern that uses basic amigurumi techniques. If you’ve made a few amigurumi before and are comfortable with magic rings and single crochets worked in continuous rounds, you’ll find this project very approachable. If you’re newer to amigurumi, don’t be discouraged — the instructions below are written in detail, and the robot’s blocky shape actually makes it one of the more forgiving forms to work with.

Let’s get started.

Materials You’ll Need

Before you pick up your hook, gather everything on this list so your crafting session goes smoothly from start to finish.

Yarn: Worsted weight yarn (Category 4) works best for this pattern. You’ll need a main color for the body — silver, gray, or light blue are classic robot choices — plus one or two accent colors for details like the antenna, buttons, or facial features. Roughly 150–200 yards of the main color and 20–50 yards of accent colors will be more than enough for one standard-sized robot.

Hook: A 3.5mm or 4.0mm crochet hook. Because amigurumi relies on a tighter fabric to prevent stuffing from showing through, you’ll want to go slightly smaller than the hook size recommended on your yarn label.

Safety eyes: Two 12mm safety eyes work perfectly for the standard size described in this pattern. If you’re making this for a child under three years old, please embroider the eyes instead for safety.

Polyester fiberfill: Standard craft stuffing. You’ll need a small to medium amount — robots are dense little things, so don’t be shy about stuffing firmly.

Stitch markers: These are essential for amigurumi. Use them to mark the beginning of each round so you don’t lose your place.

Yarn needle: For sewing pieces together and weaving in ends.

Scissors.

Optional: Black embroidery floss for stitching on a mouth, buttons, dials, or any extra detail you’d like to give your robot personality.

Abbreviations Used in This Pattern

This pattern uses US crochet terminology.

MR — Magic ring
ch — Chain
sl st — Slip stitch
sc — Single crochet
inc — Increase (two single crochets in the same stitch)
dec — Decrease (invisible decrease: insert hook into front loop only of next two stitches, yarn over, pull through both loops, yarn over, pull through remaining two loops)
BLO — Back loop only
FLO — Front loop only
st — Stitch
sts — Stitches
rnd — Round
rep — Repeat

Gauge

Gauge isn’t critical for amigurumi toys, but for reference: with a 4.0mm hook and worsted weight yarn, approximately 4 sc x 4 rows = 1 inch (2.5 cm). The finished robot will stand approximately 6–7 inches (15–18 cm) tall with these materials.

A Note on Working in the Round

All pieces in this pattern are worked in continuous rounds unless otherwise noted. Do not join rounds with a slip stitch and do not chain at the beginning of a round unless the pattern explicitly tells you to. Use a stitch marker to keep track of the first stitch of each round, moving it up as you go.

The Pattern

Head

The robot’s head is square-ish and boxy — that’s the whole aesthetic, and it’s achieved by working in the round and then doing a bit of shaping at the top.

Start with your main color yarn.

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc rep around. (18 sts)
Rnd 4: Sc 2, inc rep around. (24 sts)
Rnd 5: Sc 3, inc rep around. (30 sts)
Rnd 6: Sc 4, inc rep around. (36 sts)
Rnd 7: Sc 5, inc rep around. (42 sts)
Rnd 8: Sc 6, inc rep around. (48 sts)
Rnds 9–20: Sc in each st around. (48 sts) — 12 even rounds
Rnd 21: Sc 6, dec rep around. (42 sts)
Rnd 22: Sc 5, dec rep around. (36 sts)

Before you continue decreasing, attach your safety eyes now. Position them between rounds 13 and 14, with about 8–10 stitches between them. This gives the robot that wide-eyed, slightly surprised look that makes amigurumi so endearing. If you’re embroidering the eyes instead, you’ll add those after stuffing and closing.

Rnd 23: Sc 4, dec rep around. (30 sts)
Rnd 24: Sc 3, dec rep around. (24 sts)

Begin stuffing the head firmly at this point. Keep stuffing as you close the piece.

Rnd 25: Sc 2, dec rep around. (18 sts)
Rnd 26: Sc 1, dec rep around. (12 sts)
Rnd 27: Dec around. (6 sts)

Fasten off, leaving a short tail. Use your yarn needle to thread through the remaining 6 stitches and pull tight to close. Weave in the end.

Set the head aside.

Antenna

The antenna gives your robot its most iconic feature and is quick to make.

Using your accent color:

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnds 2–3: Sc in each st around. (6 sts)

Fasten off, leaving a long tail for sewing. Lightly stuff the antenna before attaching it, or leave it unstuffed for a more floppy look. Sew it to the top center of the head. If you’d like a ball on top of the antenna (very classic robot design), make a small bobble by starting a new piece with 6 sc into a magic ring, closing it, and sewing that to the top of the antenna.

Body

The body is larger and more rectangular than the head, giving the robot a sturdy, solid look.

Using your main color:

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc rep around. (18 sts)
Rnd 4: Sc 2, inc rep around. (24 sts)
Rnd 5: Sc 3, inc rep around. (30 sts)
Rnd 6: Sc 4, inc rep around. (36 sts)
Rnd 7: Sc 5, inc rep around. (42 sts)
Rnd 8: Sc 6, inc rep around. (48 sts)
Rnd 9: Sc 7, inc rep around. (54 sts)
Rnds 10–28: Sc in each st around. (54 sts) — 19 even rounds
Rnd 29: Sc 7, dec rep around. (48 sts)
Rnd 30: Sc 6, dec rep around. (42 sts)

Stuff the body firmly before you continue closing.

Rnd 31: Sc 5, dec rep around. (36 sts)
Rnd 32: Sc 4, dec rep around. (30 sts)
Rnd 33: Sc 3, dec rep around. (24 sts)
Rnd 34: Sc 2, dec rep around. (18 sts)
Rnd 35: Sc 1, dec rep around. (12 sts)
Rnd 36: Dec around. (6 sts)

Fasten off and close as before. Set the body aside.

Arms (Make Two)

The arms are simple tubes, slightly tapered at the end to suggest a hand or claw.

Using your main color:

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnds 3–16: Sc in each st around. (12 sts) — 14 even rounds
Rnd 17: Sc 1, dec rep around. (8 sts)
Rnds 18–19: Sc in each st around. (8 sts)

Stuff lightly — or not at all if you prefer floppier arms that pose more naturally. Fasten off, leaving a long tail for sewing.

Make the second arm the same way.

Legs (Make Two)

The legs are a little chunkier than the arms and will support the robot when it sits or stands.

Using your main color:

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc rep around. (18 sts)
Rnds 4–18: Sc in each st around. (18 sts) — 15 even rounds
Rnd 19: Sc 1, dec rep around. (12 sts)
Rnds 20–22: Sc in each st around. (12 sts)

Stuff firmly. Fasten off, leaving a long tail for sewing.

Make the second leg the same way.

Ears / Side Panels (Make Two)

These flat circular panels are attached on the sides of the head to give the robot that classic sci-fi look with side panels or ear-like features. They can also be left off if you prefer a cleaner look.

Using your accent color:

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc rep around. (18 sts)
Rnd 4: Sc in each st around. (18 sts)

Fasten off, leaving a long tail for sewing. Do not stuff — these remain flat. Make two.

Assembly

This is where your robot really comes to life. Lay all your finished pieces out in front of you before you begin sewing so you can plan the placement.

Head to body: Position the head on top of the body, centering it carefully. Use the long tail and your yarn needle to whip stitch around the base of the head, sewing it securely to the top of the body. Make sure to go around at least twice for a firm attachment, especially if the toy will be handled by children.

Arms: Attach the arms to the sides of the body at approximately round 10 from the top. Sew each arm securely, going through the body yarn a couple of times so the arms hang naturally at the sides. If you’d like poseable arms, you can insert a small piece of pipe cleaner or chenille stem through each arm before closing and then bend them into position after attachment.

Legs: Sew the legs to the base of the body, positioning them about 6–8 stitches apart from each other so the robot stands with a stable, natural stance. If your robot keeps falling forward, try positioning the legs slightly more to the front of the base than to the back.

Ear panels: Sew the flat ear panels to the sides of the head at about rounds 13–16, one on each side, aligned with the eyes.

Antenna: If you haven’t already, sew the antenna to the very top center of the head.

Finishing Details and Embellishments

This is the fun part where your robot gets its personality. Here are some ideas.

Mouth: Use black embroidery floss to stitch a simple straight line across the lower half of the face, or make a zigzag “pixel” mouth with short horizontal stitches. A grid-like pattern made with small straight stitches gives a very digital, retro-robot feel.

Chest panel: With your accent color yarn or embroidery floss, stitch a small rectangular panel onto the front of the body. Add a few French knots as buttons or dials. You could even stitch tiny plus or minus signs, or little lightning bolt symbols for extra flair.

Color details: If you’d like to add color-blocked sections, such as a different color for the lower legs or the hands, you can switch yarn color when working those sections of the arm and leg patterns. Simply join the new color yarn when you want the color to begin and carry on as normal.

Blush: A small circle of pink embroidery floss on each cheek adds sweetness, especially if this robot is destined for a nursery or child.

Numbers or letters: With embroidery floss, you can stitch a small number or initial onto the robot’s chest, making it a personalized gift.

Tips for Success

A few things that will make your finished robot look more polished and professional.

Stuff as you go rather than waiting until you’re almost closed. It’s much easier to add stuffing gradually than to force it through a tiny opening at the end. The head and body especially benefit from being stuffed quite firmly — a well-stuffed robot holds its shape and stands up better over time.

When sewing pieces together, use the same color yarn as the piece you’re attaching to make your seams invisible. If you’re attaching an accent-colored arm to a main-colored body, use the main color for the sewing yarn since that’s the surface you’ll see most of.

Use a locking stitch marker or a piece of contrasting yarn looped through one stitch to mark the beginning of your rounds. Losing track of where a round starts is the most common source of mistakes in amigurumi, and it’s completely avoidable with this habit.

If you’re new to the invisible decrease, take a few minutes to practice it before you start. It makes a noticeably neater finish compared to the standard decrease and is worth the small extra effort.

Block your finished pieces very gently with a misting of water and reshape them before the final assembly if they’ve come out looking a bit lumpy or uneven. Amigurumi usually recovers beautifully with a little moisture and careful reshaping.

Sizing Variations

This pattern creates a robot approximately 6–7 inches tall with worsted weight yarn on a 4.0mm hook. If you’d like a different size, here are two simple adjustments.

For a miniature robot, use fingering weight (Category 1) or sport weight (Category 2) yarn with a 2.5mm hook. Your finished robot will be roughly 3–4 inches tall and is adorable as a keychain or ornament.

For a larger robot, use bulky weight (Category 5 or 6) yarn with a 6.0mm or 6.5mm hook. Your robot will stand about 10–12 inches tall and makes a great cuddle-sized plush for a child.
