What Is Included in a Robot Dog Kit?

Why “what’s in the box” decides the real price

Two kits at the same price can leave you with very different shopping lists. The big variables are the main computer board, the battery, the charger, sensors, and whether the robot arrives assembled. This guide compares the kits we sell using the manufacturers’ published kit lists, checked in November 2026. Product pages carry the same information per model; before you pay, our confirmation email lists the exact package for your order.

The main kits, side by side

SunFounder PiDog ($179.99). A build-it-yourself quadruped frame with 12 metal-gear servos, camera, microphone/speaker and sensor modules, plus a 2× 18650 battery pack. The catch everyone misses: the Raspberry Pi is not included — you need your own Pi 5 / 4 / 3B+ / 3B / Zero 2 W, and a microSD card.

Petoi Bittle X ($319). A palm-sized kit with frame parts, servos, the ESP32 BiBoard controller and a battery pack. The controller is in the box, so there is no separate computer board to buy; you still need a computer or tablet for programming. Assembly takes about 40–90 minutes.

Hiwonder PuppyPi Pro ($949). A Raspberry Pi 5 configuration: Pi 5 + expansion board, wide-angle camera, TOF LiDAR for SLAM, a 7.4 V 2,200 mAh battery and an 8.4 V charger. At this price the board is part of the kit — the opposite of the PiDog.

Yahboom DOGZILLA S2, Raspberry Pi 5 version ($949). Pi 5 (4 GB) and an STM32 co-processor included, plus LiDAR, camera and a voice module. Yahboom also sells versions without the board — when you compare prices elsewhere, check which version you are looking at. Ours is the version with the Pi 5 fitted.

Unitree Go2 Air / Pro (not kits). Ready-assembled robots: the robot, its standard 8,000 mAh battery and a charger. The handheld controller is an optional extra, and spare batteries, the long-life battery and the charging dock are separate accessories. Nothing to assemble; the extras are where the extra cost hides.

The usual “required but not included” list

Across brands, budget separately for: a main board (on bring-your-own-board kits), storage cards, a computer for setup, assembly tools and time, spare batteries for longer sessions, and — on companion robots — any optional charging dock, which is bundled only in some retail packages. Apps are normally free; cloud or AI features depend on each manufacturer’s services and terms, which can change after you buy.

How to check any kit in two minutes

Find the kit list on the product page and answer four questions: Is the main board included, by name? Which battery, and is a charger in the box? Which sensors are actually fitted on this version (not the flagship version)? What does the seller’s confirmation say ships? If a listing cannot answer the first question, treat the board as not included until the seller confirms otherwise.

How PupRobot handles it

Every product page here has a “What is included” section written from the manufacturer’s kit list, and the confirmation email you receive before payment repeats the exact package contents for your order. If the email and the page ever disagree, the email is what ships — and you can walk away before paying.
