How to read a robot spec sheet
Look at status first, then autonomy, then the numbers. Height and weight tell you how it fits your home; payload, battery and runtime tell you what it can do. Only 13 of 50 robots we track publish six or more of the eight specs we compare.
1. Status: can you get one?
"Shipping" means orders deliver now. "Pre-order" means you pay a deposit for a later delivery. "Pilot" means it works in a few businesses but isn't sold. A launch video says none of these. Every robot page here shows a status badge with its source.
2. Autonomy: who is in control?
Autonomous robots act on their own. Teleoperated ones can be driven by a remote person. Developer platforms do what you program. Remote-controlled ones follow your app. This matters more than any number below.
3. The numbers
| Spec | What it tells you | Published by |
|---|---|---|
| Height | How tall it stands. Compare with your counters and your kids. | 33 of 50 |
| Weight | What you would lift if it falls over, and what it could knock over. | 31 of 50 |
| Payload | How much it can carry or lift. Makers often quote a peak, not a sustained figure. | 18 of 50 |
| Battery | Energy stored, in watt-hours. Bigger usually means longer runs. | 15 of 50 |
| Runtime | How long it runs between charges, in the maker’s own test conditions. | 30 of 50 |
| Joints (degrees of freedom) | How many ways it can move. More joints mean finer movement, not more intelligence. | 19 of 50 |
| Walking speed | Normal walking or driving speed, in metres per second. | 7 of 50 |
| Top speed | Fastest speed the maker states, often running. We show the maker’s own label. | 18 of 50 |
4. What spec sheets leave out
- Noise, and how it handles stairs, rugs and cables.
- Whether demo tasks need a remote operator.
- What data it sends to the maker.
- Repairs, parts and software support after purchase.
Our spec tables use only the maker's or an authorized seller's figures. Reported figures from news are shown separately as dated facts. A dash means it isn't published, not zero. See how we verify. Checked Oct 24, 2026.
Example: walking speed is not top speed
The 1X NEO lists a walking speed of 1.4 m/s and a max run speed of 6.2 m/s on the same page. A table that shows one number as "speed" hides that difference. We show each speed with the maker's own label, and compare top speeds only when both makers state one.
Example: one name, several editions
The Unitree R1 comes in 3 editions: R1 AIR ($4,900, 27 kg, 20 joints), R1 ($5,900, 29 kg, 26 joints), R1 EDU (Contact sales, 29 kg). Only the R1 EDU can be programmed by owners. The cheapest price and the full spec sheet often belong to different editions.
