What a dexterous hand costs per actuated degree of freedom
Dividing public prices by actuated DOF gives a range of $129 to $1,500, an 11.6x spread that tracks control electronics, not finger count.
The short version
Five hands with a public price and a published DOF count land between $129 and $1,500 per actuated degree of freedom. The cheapest per DOF is the LEAP Hand at $129 and the most expensive is the Unitree Dex5-1 at $1,500, so per-DOF cost is a floor for the mechanism, not a proxy for what the hand can do.
Five hands on this site carry both a public price and a published actuated DOF count. Divide one by the other and they land between $129 and $1,500 per actuated degree of freedom. That is an 11.6x spread inside a category where buyers often compare spec sheets as if the numbers were commensurable.
The figure is not a quality score. It is a floor: the money that buys the motors, the structure that holds them, and the wiring that reaches them. Everything a hand is judged on in a lab, from tactile arrays to force control, sits on top of that floor and varies independently of it.
| Model | Cost per actuated DOF | Low price as published | DOF |
|---|---|---|---|
| LEAP Hand | $129 | $2,066 | 16 |
| Leadshine DH116S | $383 | $2,299 | 6 |
| Allegro Hand V5 | $812 | $13,000 | 16 |
| Inspire RH56DFX | $933 | $5,600 | 6 |
| Unitree Dex5-1 | $1,500 | $24,000 | 16 |
Where the ratio comes from
Each row divides the lowest published price in the price panel by the DOF count in the model's record. No averaging across channels, no conversion between currencies, no adjustment for what ships in the box. The LEAP Hand record carries three US observations between $2,066 and $4,550; the $2,066 figure is used here because it is the published entry price for the v1 assembly kit.
Two of the five are kits or near-kits. The LEAP Hand ships as printed parts and servos that the buyer assembles, which is why 16 DOF clears under $2,100. The Leadshine DH116S record is a finished six-DOF hand at $2,299, so the per-DOF number is higher even though the sticker is barely above the LEAP kit.
Why industrial hands cost more per DOF
A finished hand at $800 to $1,500 per DOF is not being marked up for the same mechanism. The difference shows up in three places.
- Control electronics. A six-DOF hand can run off a single controller board. A sixteen-DOF hand needs distributed drivers and a bus that holds timing under load.
- Sensing. Encoders at every joint, and in some models tactile pads, add cost per DOF rather than per hand.
- Integration and support. A dealer who keeps a replacement on a shelf in Ohio is selling a service that a kit does not include, and the RH56 channel spread shows what that service is worth in the same year.
The exception that proves the rule is the Unitree Dex5-1: $24,000 for 16 DOF, or $1,500 per DOF, in a product positioned for a humanoid platform rather than for a research lab buying one unit.
The RMB rows do not belong in this table
Two records on this site publish in RMB. The LinkerBot O6 lists 3,900 RMB for six DOF, which is 650 RMB per DOF, and the PaXini DexH13 lists 98,000 RMB for thirteen. Neither is converted here, because converting at today's rate and publishing the result would create a dollar figure that no vendor ever quoted and that the next reader cannot reproduce. The method page explains why the record keeps currencies apart.
How to use this in a quote
Ask for the DOF count in the same sentence as the price. A vendor who quotes a per-finger number, or who counts joints rather than actuators, is answering a different question. The DOF primer covers the distinction; the RFQ template puts both fields in one email so the answers can be compared.
Three questions turn the ratio into a decision:
- Is the quoted price for a kit, a finished hand, or a hand plus controller?
- How many of the published DOF are actuated, and how many joints follow the actuator mechanically?
- What does a replacement cost, and who pays freight on a failed unit?
None of that requires a lab. It requires the same four numbers from every channel, written down.
What this measure cannot tell you
Per-DOF cost does not predict grasp quality, repeatability, or how long the hand survives a million cycles. A hand at $129 per DOF and a hand at $1,500 per DOF can both fail on the same tendon, and the cheaper one may be easier to repair because the parts are printed and the servos are commodity stock.
It also cannot compare a hand with no public price. The Shadow Hand and the ORCA Hand are quote-only and not-published respectively, and a ratio built on an estimate would be a guess wearing a number.

Questions
Is a lower cost per DOF always better?
No. Per-DOF cost only compares the actuated mechanism. It says nothing about tactile sensing, encoder resolution, control electronics, backlash or the warranty behind the unit, and those are where the expensive failures happen.
Why does the LEAP Hand come out so cheap per DOF?
It is sold as an assembly kit with 3D-printed structural parts and Dynamixel servos, at $2,066 for 16 DOF. Assembly and wiring move to the buyer, which is why the price per DOF is $129 while a finished industrial hand sits above $800.
Should DOF or joints be used in the denominator?
DOF. A finger with three joints driven by one motor is one actuated DOF with three joints, and dividing by joints flatters the hand by a factor of two or three. Compare like with like and say which number the vendor published.
