I constructed my very own robotic canine, and it wasn’t tough. That doesn’t imply I’m a robotics engineer or an electronics tinkerer. I took an electronics class in highschool, however no oscilloscopes, multimeters, or soldering are required to make this cyberdog.
It isn’t as large and powerful as Boston Dynamic’s Spot, however itcosts a lot much less. It’s not as cute as Sony’s Aibo, which has been round lengthy sufficient that Sony has instituted a foster care program for its getting old robotic canine.
Nevertheless, Petoi’s Bittle X is a enjoyable, reasonably priced robotic canine equipment that’s instructional and customizable for open-source initiatives. I put it collectively and discovered learn how to troubleshoot connections, calibrate joints, and work together with my little good friend. Right here’s how I did it.
What can Bittle X do?
When absolutely assembled and calibrated, Bittle X turns into a remote-controlled, quadrupedal robotic. I can connect with it by way of my pc or telephone.
The Petoi cell app has arrows to information Bittle to stroll, crawl, or trot in any course, in addition to an inventory of buttons to carry out quite a lot of methods. Bittle X can wave, sit, play useless, stretch, and extra.
If the robotic journeys or falls, it robotically flips again over. It’s a sturdy gadget fabricated from high-impact plastic, so it ought to final a few years.
I can use a distant for preset instructions. I may also train this robodog new methods. Within the pc app, drag-and-drop command blocks enable the creation of customized motion sequences. It’s additionally attainable to code in C++ or Python for extra sophisticated programming. For instance, there’s a customized sequence to permit Bittle X to cross a large hole, as proven within the video beneath.

Bittle X additionally understands voice instructions, and Petoi programmed in a large library of over 40 phrases, some fairly spectacular. In case your little buddy doesn’t reply, strive saying “play sound,” or “bing-bing” to modify to English.
If the cyberdog understands you, it’ll “converse” to let you recognize. The speech is tough to grasp, nevertheless it’s nonetheless satisfying to listen to a response because it prepares to carry out a stunt. Bittle X can do a backflip, entrance flip, handstand, and extra.
Constructing Bittle X
It’s comparatively straightforward to place the Bittle X collectively. It took me just a little over an hour. There are many tiny screws, a small magnetic screwdriver, a group of servos, leg components, the physique, a preassembled head, circuit board, and battery.
The directions are moderately clear, however I needed to change from directions particular to Bittle X to a extra normal information midway by way of, then again once more to complete.
The elements have delicate variations, so I attempted to test fastidiously earlier than attaching a component. I needed to redo a couple of steps.
The fussiest half is arranging the wires and plugging them into the proper plugs. I’ve large arms, and there isn’t a lot room to maneuver contained in the physique.
I had additional items left after utterly assembling Bittle X, spare components in case some are misplaced or broken. The subsequent step is calibration, the place I discovered what I did fallacious.
In calibration, Bittle X rotates its limbs at proper angles. The higher legs ought to be vertical, whereas the decrease legs are horizontal. My robotic had some bizarre angles. I attempted utilizing the cell app to appropriate the difficulty, however some had been too far off, so I eliminated and reattached them appropriately.
One other calibration take a look at revealed some parts weren’t shifting in any respect. I eliminated the again and unscrewed the circuit board and found I missed a pin after I plugged them in.
After correcting the errors, I may fine-tune to make minor angle changes with the plus and minus calibration controls.
Already, Bittle X was educating me about taking care when assembling components and, notably, when plugging in electronics. I’m comfortable the Bittle X design is strong sufficient to forgive my errors. After fixing these errors, every little thing labored as anticipated.
However I’m a cat individual
Petoi sells three Bittle robotic canine fashions. The Bittle X makes use of an ESP32 BiBoard, whereas the Bittle STEM and Robotics Equipment use an Arduino UNO-compatible NyBoard. ESP32 BiBoard is quicker, whereas the NyBoard is extra suitable with the maker neighborhood for add-ons and customization.
Should you’re a cat individual, that isn’t an issue as a result of Petoi’s earlier robotic pet, Nybble, is a cat. That explains why the corporate emblem appears to be like feline.
Nybble is fabricated from wooden, whereas Bittle makes use of high-impact plastic. Nybble doesn’t have Bittle’s built-in Bluetooth or Wi-Fi connectivity both. Cats are finicky like that, however you may add these options should you’d like.
In contrast to precise cats, Nybble is a bit bigger and heavier than Petoi’s robodog Bittle, requiring extra meeting. Petoi estimates setting up Nybble takes about 4 instances so long as it does to place Bittle collectively.
Is Bittle X best for you?
Bittle X has a horny worth — $280 is tough to beat for a whole quadrupedal robotic with Wi-Fi and Bluetooth connectivity. It additionally features a distant management, so that you don’t have to depend on a pc or a telephone to maneuver your robotic pet round.
If you wish to discover robotic {hardware} or software program, that is a simple approach to take action. I’ve barely scratched the floor of what’s attainable with Petoi’s Bittle X. Take a look at the spooky enhanced Bittle in Petoi’s video beneath.

Should you’re in search of a hassle-free toy robotic, this isn’t the fitting alternative. In order for you a robotic that may do actual work like Amazon’s Astro, Bittle X may not be strong sufficient. Its battery life is about one hour of steady strolling.
The Bittle X would make a beautiful reward for kids (10 and older) all for science. Possibly they’ll assist develop robots that may discover the photo voltaic system or design a futuristic humanoid robotic that may do something a human can. Massive youngsters, like my spouse and I, get pleasure from Bittle X additionally.
