Humanoids / brief

The only soft hand a humanoid can carry.

Humanoids don't work in controlled cells. They work everywhere else. Soft fingers with precise electric control are the only end-effector designed for that reality.

The problem with rigid

Rigid fingers are built for structured environments. The real world isn't.

Industrial grippers work because the environment is engineered around them — fixed positions, known objects, repeatable presentations. Humanoids inherit none of that. A general-purpose robot has to handle a coffee cup, a bag of groceries, a door handle, and a fragile patient — in any order, in any setting.

Every pick is unknown.

Rigid fingers need exact object models and repeatable positions. In a home, hospital, or retail environment, neither is guaranteed. Any variation in pose or shape becomes a failure.

Rigid means dangerous.

A rigid jaw applies its programmed force regardless of what is in its path. Around people — especially vulnerable people — that is not a feature. Safety has to be intrinsic, not programmed.

The environment won't adapt to the robot.

In structured automation, you engineer the object presentation to suit the gripper. With a general-purpose humanoid, you can't. The hand has to handle what it finds.

The solution

Soft compliance. Precise control. Neither alone is enough.

Soft fingers handle what rigid ones can't — they conform, absorb variation, and operate safely around people without a cage. Electric actuation then adds what pneumatic soft grippers lack: precise force and position feedback, readable grip data, and no compressor to carry.

Inherently safe and adaptable.

Soft silicone fingers deflect under unexpected load instead of transmitting force. They conform to shape variation without explicit grasp planning for every new object.

Precise force and position control.

Programmable grip force, set per task on the fly. Individual control and readable feedback on every finger. The precision of a controlled actuator with the feel of a soft hand.

Runs on what the robot already has.

24 V DC. No compressor, no air lines, no external infrastructure. The same power and data interface as every humanoid platform shipping today.

Already shipping

We've been building the right hand for years. The market just caught up.

Ubiros has been deployed in production cells at Tier-1 suppliers, food processors, and labs since 2021. The control stack, the silicone formulations, the Python API — none of it is a prototype.

Built for the humanoid spec sheet

A finger that fits the body.

Power 24 V DC. Same battery system as every humanoid platform on the market.
Mass Sub-kilogram per finger pair. Mounts at the wrist without unbalancing the arm.
Force range Programmable from 0.1 N (eggshell) to 50 N (door handle). Set per task, on the fly.
Compliance Soft food-grade silicone tips. Adapts to any geometry without explicit grasp planning.
Interface Digital I/O or Ethernet over Python API. Plays cleanly with ROS, the dominant humanoid stack.
Maturity 1.5M+ documented cycles in production. Not a roadmap item.
