PhoeniX is a lower body-powered hip exoskeleton designed to assist people with mobility impairments.  It is being developed by SuitX, formerly US Bionics.  The company was created by Professor Homayoon Kazerooni, who has founded and inspired other exoskeleton companies in the past.

The PhoeniX is especially engineering to be inexpensive and accessible.  It is currently undergoing testing.


The PhoeniX is being developed by SuitX (trademark of US Bionics, Inc).  The main design goal for the SuitX is to be the least expensive of the powered gait rehabilitation exoskeletons.

The PhoeniX sports a lightweight design, further simplified by having actuation only at the hips.  This brings the cost and weight down.  The exoskeleton knee component locks in place while standing or bearing weight and unlocks during the leg swing phase.

The exoskeleton is also compatible with traditional orthotic devices.  You can use your own orthotic and just add actuation at the hips.  As a tradeoff, the PhoeniX is not capable of providing full assistance while climbing stairs.

Initially, the device will be available only to rehabilitation centers until regulatory approval is acquired.

Design intent:

  • Modular
  • Total weight of only 12.25 kg (27 lbs)
  • Maximum recorded speed of 0.5 m/sec (1.1 miles/hour, this is usually used to determine if the suit allows for enough time to cross a traffic light)
  • Four-hour battery life while in continuous use
  • Comfortable to wear while in a wheelchair (due to its small size)

    One question,
    In the picture, the PhoeniX seems to have a pair of wireless crutches. Am i right?

    • Bobby Marinov

      Hello Anna, to my knowledge the Phoenix is controlled using via the crutches which use wireless communication, most likely Bluetooth. For the exact details, however, it would be best to contact SuitX. For the record, I have not seen crutches with direct wires running to the exoskeleton in any of the modern exos.

      Your best bet is to contact suitX directly.
