Name: ZeroG 3D
Brand: Aretech

Overview

Move freely in any direction.

Patients move forward, backward, side-to-side, and in circles. Because ZeroG 3D operates across a large workspace rather than a fixed path, clinicians can safely simulate complex, high-level activities that were previously difficult to train.

Multidirectional freedom Lateral agility drills and dynamic stepping in every plane of movement.
Reactive balance Navigate obstacles to practice reactive balance and recovery responses.
Activities of daily living Rehearse real-world tasks through simulated home environments.

Dynamic body-weight support during agility training

Dynamic Body-Weight Support + Explore

Dynamic BWS

Dynamic Body-Weight Support

Offloads a set portion of the patient's body weight and keeps it steady as they rise and lower — so demanding movements become both achievable and safe to attempt.

Functional Independence

Support stays constant through the most demanding phase of a movement such as getting off the floor, never fluctuating mid-movement. Clinicians can adjust the level of BWS to progress the challenge session by session.

Constant Support

With support that never yo-yos, patients can give their full attention to the movement itself — rebuilding strength and relearning functional tasks with confidence.

Achieve Milestones

Standing up is where it starts. By offloading just enough weight to get a patient upright, Dynamic BWS puts that first milestone within reach.

Remove Barriers

Patients feel lighter with every step as ZeroG 3D offloads a precise portion of their weight in real time. Tasks that would otherwise be out of reach become safe, repeatable parts of the session.

3-Dimensional Tracking + Explore

3-Dimensional Tracking

Tracking that moves with the patient.

Omnidirectional tracking follows the patient in any direction — supporting walking, turning, side-stepping, and complex multidirectional tasks.

Play

Turn therapy into play. Children explore their space through movement and exploration without restriction, keeping young patients engaged.

Activities of Daily Living

Room to rehearse everyday life — circling a table, reaching across a counter, and moving through a kitchen the way they would at home.

Customizable Boundaries

Shape the tracking around the session — lock the long axis into a straight-line track, open it to full 3D for free ambulation, or create a custom path or box for task-specific work.

Peak Performance

Fast enough for full-effort gait, sport-specific drills, and high-intensity training. ZeroG 3D tracks patients up to 5 mph in any direction — the fastest 3D system on the market.

Fall Protection + Explore

Fall Protection

Push limits, without the risk.

Fall protection engages by distance or by speed, configured for each patient and every activity, so patients can push their limits with confidence.

Build Confidence

Knowing a fall is caught before it can cause injury, patients gain the confidence to push their limits and attempt tasks they'd never risk otherwise.

Hands-Free Therapy

Because ZeroG 3D is the safety net, clinicians can step back and let patients take on activities that wouldn't be safe with hands-on guarding alone.

Set for Every Task

Set the allowable distance down to an inch, or engage by the speed of a fall — customized per activity so high-stakes work like stairs stays safe.

Disabled

For higher-level patients or floor-based work, switch fall protection off completely for unrestricted movement, while dynamic body-weight support stays active.

User Interface + Explore

User Interface

Operate correctly from day one.

Plain-language, plain-text controls built to FDA human-factors standards — so any clinician runs ZeroG 3D correctly from day one, with no icons to decode or new visual language to learn.

Ease of Use

Takes the burden off the clinician so the buttons do the heavy lifting.

Touchscreen Computer

A full-size touchscreen that plugs in wherever it's most convenient for the clinician.

Hand-Held Remote

For flexibility, clinicians can use the remote to change settings on the fly while remaining right next to the patient.

Installation + Explore

Installation

One team, start to finish.

Every ZeroG 3D installation is engineered in-house by Aretech, then carried out by seasoned crews who install nothing but our own technology.

Planned In-House

Aretech engineers plan each install in-house — one team, one point of contact, and full accountability.

Full Accountability

From the first site visit to the final handoff, your project never leaves our hands.

Arcade 3D

Therapy that feels like play.

Arcade 3D is a suite of adaptive, interactive games fully integrated with ZeroG 3D. Patient movements drive the gameplay in real time, combining dynamic motor challenges with cognitive tasks on a 55-inch display. Target postural control, dual-tasking, and high-intensity training while patients stay engaged in therapy that feels like play.

Postural

Postural Games

Build static and dynamic balance through weight-shifting and sway-control tasks.

Dynamic

Dynamic Games

Drive high-intensity therapy with games that respond to every step, stride, and direction change.

Cognitive

Cognitive Games

Pair movement with memory, attention, and decision-making to rebuild real-world dual-tasking skills.

Ecosystem

Built to grow with your program.

Arcade 3D is just the beginning. A suite of optional add-ons expands workspace coverage, extends clinical capabilities, and lets you train multiple patients simultaneously.

Second Robot

Double your treatment capacity in a single space. A second robot lets two clinicians run simultaneous sessions, maximizing throughput during peak hours.

Passive Trolley

Add a safety net without a second robot. The Passive Trolley is a static fall-protection trolley that mounts to the frame, protecting patients who are at risk of falling.

Extended Workspace

Your space is the only constraint. Add as much workspace length as the room allows, so patients can practice longer distances and more complex routes — all within continuous 3D support.

Pulse Oximeter

Add real-time cardiovascular monitoring. Track heart rate and SpO₂ to train within prescribed Heart Rate Zones for cardiopulmonary rehab and high-intensity work.
