Introducing the ReFlex Hand

Bring your research to the cutting edge with the ReFlex Hand. It is built on over a decade of research in the Harvard Biorobotics Lab and the Yale Grab Lab, and it leverages the best insights our team gained from creating the top-performing design in the DARPA Autonomous Robotic Manipulation program's Hardware Track[1].

The hand provides three mechanically-intelligent underactuated fingers, highly sensitive tactile feedback, and a solid interface designed by the Open Source Robotics Foundation (of ROS fame).


The system consists of: a 3D-printed palm filled with Dynamixel servos; a smart palm and smart fingers equipped with tactile sensors and encoders; an interface circuit board; and a basic software driver to publish motor commands and read sensor values. The software will be developed as an open-source project under the BSD licence. This ensures that the core functionality can be shared and improved by the ReFlex community.

ReFlex hand is compatible with a variety of robots including WAM, Universal Arm, and Baxter.

Beta Program

The ReFlex is currently closed, with hands shipping to ten top universities on four continents.

ReFlex SF

A low-cost version of the hand is available for order now (lead-time 8 weeks) including all the mechanics of the ReFlex, but no sensors. Cost $4999. Trade-up program provides $4K discount on ReFlex Full product.

ReFlex Pre-Orders

We are accepting orders for the ReFlex hand for $14999 for shipment in 2015. Priority will be given to ReflexSF customers. features subject to change
