Comparison
Inspire RH56 vs LEAP Hand: five fingers or sixteen motors
One is a sealed product built for integration. The other is an open kit built for experiments. The price overlap is narrower than the numbers suggest.
The RH56 wins when the hand has to arrive, bolt on and work, and when five fingers matter for the demo. The LEAP Hand wins when the work is research, the hand will be modified, and independent finger control is the point.

The price overlap is an illusion
At $5,600 the Inspire hand looks like a $3,500 premium over a LEAP kit for a sealed five-finger product, which is reasonable. At $20,599 it looks absurd. Both prices are real and neither is the list price, because Inspire has no published export price. The RH56 price record keeps all four observations instead of averaging them, and that is the first thing to settle before comparing anything else.
Six motors against sixteen
The RH56 has six actuators driving 12 joints. The fingers curl in coordinated patterns through linkages, which is enough for power grasps, pinch grips and the ordinary work of moving objects from one place to another. It cannot move one finger independently of its neighbours, and no amount of software changes that.
The LEAP Hand has one motor per joint. That is what makes it the standard platform for reinforcement learning: the action space is 16-dimensional and every dimension is real. It is also why the hand is heavier and why there are 16 servos to fail.
What the choice actually turns on
- Does the hand need to look like a hand? A five-finger anthropomorphic shape matters for teleoperation, demonstrations and anything shown to a customer. Four fingers with a thumb works fine for grasping.
- Will anyone modify it? Once a lab starts printing fingertips, the open design stops being a nice-to-have.
- Who supports it? A sealed product with a vendor SDK shifts the integration work to the supplier. A kit shifts it to you.
- Where does it ship from? Both have channel structures that change the landed price, and the landed-cost guide covers what gets added.
Questions
Which is better for teleoperation?
The RH56, for the five-finger shape and sealed hardware. The LEAP Hand is usable but the four-finger layout limits retargeting from human hand data.
Can the RH56 be used for RL research?
Only within a six-dimensional action space. If the experiment depends on independent finger control, it cannot.
