## Indications for Use

The iBOT® Personal Mobility Device ("iBOT® PMD") is intended to provide indoor mobility to persons restricted to a sitting position who meet the requirements of the user assessment and training certification program. The device allows for the option to climb stairs. Companions who are required to provide assistance during Assisted Stair Climbing Mode must meet the requirements of the training certification program. The iBOT® Personal Mobility Device ("iBOT® PMD") Occupied Transport option is indicated for providing persons, unable to transfer from their wheelchair into a standard factory motor vehicle seat, the option for transportation while seated in their iBOT® PMD wheelchair.

## Device Story

iBOT® PMD is a multi-mode powered wheelchair for indoor/outdoor mobility; enables stair climbing, curb traversal, and obstacle navigation. Input: user commands via joystick/controller; internal MEMS sensors/absolute position sensors monitor orientation/stability. Operation: active stabilization system maintains balance in various modes (Standard, 4-Wheel, Balance, Stair-climbing, Remote, Docking). Output: powered movement; elevated seat height for daily living activities. Used in home/community settings; operated by patient or trained companion. Healthcare providers use device to facilitate mobility/independence. Benefits: improved accessibility, eye-level interaction, and safe occupied transport in motor vehicles. Updates from predicate include helical gear train for noise reduction, redesigned brake release, and occupied transport capability compliant with ISO 7176-19.
