Run the Two-Markets Test
Every robot dog list mixes products that cannot be compared. Unitree Go2 has a public price and a cart. Boston Dynamics Spot is a commercial inspection platform sold through a sales conversation. Sony aibo is not a quadruped platform at all; it is a robot pet.
The Bot Scout two-markets test sorts before it ranks: does this machine have a published price and a checkout, or does it require a sales process and a deployment plan. Those are different buyers, different budgets, and different support expectations.
Ranking across that line produces nonsense, which is why a $2,800 hobby quadruped regularly appears in the same list as an enterprise inspection robot with no published price.
| Platform | Market | Access | Best fit |
|---|---|---|---|
| Unitree Go2 | Public price | Official checkout, import terms apply | Hobby, development, mobile experimentation |
| Unitree research quadrupeds | Public price | Checkout with edition differences | Labs needing SDK and sensor access |
| Boston Dynamics Spot | Enterprise quote | Sales conversation | Inspection routes with payload and support |
| Sony aibo | Consumer retail | Official checkout | Pet-like companionship, not a platform |
| Toy quadrupeds | Consumer retail | Retail listing | Novelty; verify age and battery safety |
What Each Market Should Verify
On the public-price side the questions are export and support: which entity sells to your country, what import duties and clearance apply, where warranty and repair sit, and what development access the specific edition permits — the export-path discipline in the Chinese robots guide.
On the enterprise side the questions are route and data: sensor payload, route completion, environmental rating, connectivity, and who analyses the data afterwards, which is covered in the inspection robots guide.
If the goal is a pet rather than a platform, the category split is in the robot dog for sale guide and the robot pets guide.
- Sort by public price versus sales quote before ranking anything.
- Confirm the legal seller and warranty territory for your country.
- Check which edition permits secondary development.
- For inspection, specify sensor payload and the data workflow.
- Do not compare a robot pet with a research quadruped.
Why Robot Dogs Beat Humanoids for Some Jobs
A quadruped does not need human-like balance, which makes it more practical than a humanoid for mobility, outdoor terrain, and carrying sensors along a route.
It also cannot use human tools, open most doors, or manipulate objects at a workstation. Where hands matter, the quadruped is the wrong body regardless of how well it walks.
Compare the body-shape decision directly in the humanoid robot comparison before assuming legs are the deciding feature.
Bottom Line
Robot dogs are two markets sharing a silhouette. Sort by public price versus sales quote first, then verify export and support on one side and route and data on the other.
Decide whether you need a public-price platform or an enterprise inspection system before comparing specifications.
FAQs
Which robot dog can I actually buy?
Unitree publishes public prices and a checkout for its quadrupeds including Go2. Boston Dynamics Spot is sold through a sales conversation rather than a listing.
Is Sony aibo a robot dog?
It is a robot pet rather than a quadruped platform. It is built for interaction and companionship, not for carrying sensors or running inspection routes.
What is the difference between a hobby and an enterprise quadruped?
Public price and checkout versus a sales process with a deployment plan, plus very different expectations for payload, environmental rating, service, and support.
Are robot dogs more practical than humanoids?
For mobility, outdoor terrain, and carrying sensors, often yes, because they do not need human-like balance. Where hands and human tools matter, they are the wrong body.
