Nybble Q
Limited evidenceRead the findings →Petoi's ready-built robot cat that walks, does tricks, obeys spoken commands and teaches coding. It suits older children, classrooms and adult tinkerers. It's fiddly in places, though, and isn't a cuddly pet.

What we know
Make:, the one finished review, used a ready-built Nybble Q as its go-to robot to show off to guests, and a quick demo persuaded a teacher friend to buy one for his classroom. Make praised the voice recognition and the lessons, but calls Petoi's robots intermediate projects rather than foolproof products, and had to open the cat to fix a tail that wouldn't wag. Learn With A Robot spent a week with an early-access unit before launch and liked its solid build and extra head and tail movement.
Make:, hands-on, Aug 2025 (tested on the Nybble Q (ready-built), tested alongside Bittle X V2) · Learn With A Robot, hands-on, Apr 2025 (Early-access unit, a week before launch; A one-week preview of an early-access unit before launch)
Voice commands work well
Make: had a lot of fun discovering the built-in responses to spoken commands, and found the recognition accurate enough that it seldom reached for the remote. There were some amusing mix-ups: "coffee table" became "be table". Petoi lists more than 35 commands and lets you add up to 10 of your own, per the specifications. Expect to enjoy talking to it, but don't expect a conversation.
A project, not a finished toy
Make: says these aren't foolproof consumer products but intermediate projects, where someone has done the hard development so you can skip to the fun part. Its cat arrived ready-built, yet the tail wouldn't wag until it moved a servo plug. Taking off the back was quick and needed no tools, but it exposed a delicate ribbon cable. Be ready to open it up now and then, or give it to someone who'd enjoy doing that.
Steady on its feet, mostly
When a trick went too far, Make: found the cat's balance sensor told it to flip back over. That worked well, though it took a few seconds to find its feet on smooth surfaces. Learn With A Robot found the 3D-printed body solid in the hand. Make: still suggests Petoi's Bittle X if you want something more durable, so keep Nybble Q on the floor or a table and away from rough play.
Room to grow with coding
Make: liked the included coding lessons, and found an active online community covered gaps in the hardware documentation. You program it with blocks, Python or C++, and can add a Raspberry Pi for more computing power, per the specifications. Learn With A Robot describes it as compatible in every way with Petoi's Bittle X dog. It also points out that, unlike older Petoi robots, it isn't sold as a kit to build yourself.
Our take
Should you buy the Nybble Q?
Best for: Children aged ten and over, or adults, learning to program a walking robot. Skip it if: You want a finished companion without assembly or troubleshooting.
buy it for a child of ten or over, a classroom or an adult who wants a robot to program and prefers cats to dogs. Petoi's Bittle X is the one to pick if you'd rather build the robot yourself or want something tougher.
Nybble Q is Petoi's robot cat, the successor to the wooden Nybble kit. It comes ready-built in a 3D-printed body with better motors and the same family of control board as the Bittle X dog, and because it isn't sold as a kit you don't learn by building it. It understands more than thirty-five spoken commands, has distance-sensing eyes, and you program it with blocks, Python or C++.
Make: used a ready-built Nybble Q alongside the Bittle X. It found Petoi's voice recognition accurate enough to seldom need the remote, used the cat as its go-to robot to show guests, and a quick demo persuaded a teacher friend to buy one for his classroom. It still had to move a servo plug, and it picks the Bittle as the more durable of the two. The hour of walking per charge is Petoi's claim, and Petoi says there's no subscription and lists no camera.

Before you buy
The questions people ask about this one
Is it suitable for young children?
Petoi says it's ideal for ages 10 and up, with younger children joining in under adult guidance, per the specifications. Make: calls Petoi's robots intermediate projects, and it had to open the back to fix a loose servo plug. Younger children will enjoy the tricks and voice commands but will need an adult for fixes and coding.
How long does the battery last?
About an hour of continuous walking, and about 1.5 hours to recharge over USB, according to the specifications. Neither Make: nor Learn With A Robot timed it. Plan on one play or coding session per charge.
Does it need a subscription to keep working?
Petoi doesn't mention one. You control it by voice or through Petoi's app, and code it with free lessons, per the specifications. Make: found the voice commands worked well enough that it seldom reached for its remote.
What does it record, and where does that go?
Petoi doesn't list a camera. The cat senses the world through ultrasonic distance-sensing eyes and listens for voice commands, and you connect to it over Bluetooth, per the specifications. Learn With A Robot notes you can add a Raspberry Pi, and anything you connect that way brings its own privacy questions.
Cat or dog: Nybble Q or Bittle X?
Make: tested both. It found Nybble Q's distance-sensing eyes a neater option for roaming on its own, but suggests Bittle X if you want an extra arm or something more durable. Learn With A Robot adds that Bittle X is also sold as a kit, while Nybble Q only comes ready-built.
Alternatives
Other companion robots to compare.
Bittle X
Why consider it: The robot dog on the same system, sold as a kit or ready-built, with two hands-on reviews.
The compromise: It's a dog, not a cat, and it lacks Nybble Q's distance-sensing eyes.
Moflin
Why consider it: Another touch-first companion, soft and furry rather than plastic, that doesn't record speech.
The compromise: It needs recharging on its bed, and it's about cuddles rather than games.
EMO
Why consider it: A small desk character that dances and butts in while you work.
The compromise: Owners report patchy voice recognition, and it isn't built for coding lessons.
