AORTER takes its name from the Ancient Greek ἀορτήρ (aortēr): the ancient sling the Greek Hoplites used to wield their sword and shield.
The sling from which the sword and shield were hung.
Modern webbing and clips for carrying items, including limbs.
Wearable support mechanisms expanding human assistance.
The evolution of the arm sling.
A continuous bilateral pathway connects movement on one side of the body to usable support on the other. When one side pulls, the cord travels through the central mechanism and changes the connected state across the opposing side. The task remains yours, but the demand gains a controlled path through which it can be shared, resisted and returned.
Adjustable, quick-release tethering connects limbs, tools and loads through a single retractable cord, redirecting wearer-generated movement into usable support across a range of tasks without motors, batteries, air tanks or any form of added power.
Your muscles still control the work. AORTER reallocates demand rather than claiming to eliminate it. Connected working points help the arms spend less of the task holding static load and remain available to steer, manoeuvre, position and respond.
Movable sheaves, guided travel and selected resistance give repeated tool oscillation a controlled mechanical path. The resulting vibration or tremor response depends on the configured tool, cord, resistance and attachment geometry.
Research and development has reached alpha release. AORTER is ready for early adopters.
Enquire About AvailabilityAORTER routes wearer-generated movement through one continuous mechanical pathway. Feel free to explore how the endpoint configuration changes while the underlying patented architecture remains connected.
Normalized engineering model derived from ideal cord-length and pulley constraints. It demonstrates architecture, not calibrated product loads, efficiency, safety limits or clinical performance.
A single cord tracks around tension-adjustable sheaves, with free ends on opposite sides and at least one movable central sheave carried by a linear track bearing.
Fixed left/right redirectional sheaves and movable central sheaves may be adjusted independently; spring-loaded linear bearings provide resistance as the sheaves travel.
Flexible tubes guide the cord, hinged supports direct its free ends, and the cord may be anchored or stretchable according to the claimed configuration.
The lift-assist claim combines redirectional and movable central sheaves, resistance-equipped linear bearings, free cord ends and hinged shoulder routing.
Most exoskeletons begin where strain is reported: the back. AORTER begins at the hands, where the lift starts. From there, one continuous pathway connects both working sides before demand concentrates through the arms or reaches the paraspinal musculature.
The goal is not to interrupt natural movement. It is to let the pathway move with it, reducing holding demand while preserving control, adaptable fit and the wearer’s own working rhythm.
Sustained elbow flexion and shoulder elevation can concentrate demand through the biceps, brachialis, anterior deltoid and upper trapezius. The upper-forearm and wrist tether intercepts a configured portion of lift-related demand before it remains concentrated through the wrist, antebrachial region, forearm and bicep.
Through the continuous cord, downward contribution from the opposing tricep creates lift assistance on the loaded side. The vest and internal lever structure then direct the configured reaction toward the abdominal system and lower body rather than presenting it as load transferred into the shoulder.
Attachment position, resistance, spring setting and task geometry determine the response. Optional posterior lower-body anchors can extend the pathway farther toward the legs. With both endpoints carrying a shared object, the neutral 50/50 setting balances participation between the connected sides. The precise change in muscle activation depends on the task and configuration.
AORTER keeps the wearer inside the feedback cycle. Because the pathway is bilateral, fluid and body-connected, movement on one side is immediately felt through the opposing side as assistance, resistance and return.
AORTER does not remove muscular work. Its neutral 50/50 setting represents equilibrium between connected sides. Intention produces movement, movement produces support, and that support returns through the same continuous pathway.
This uninterrupted relationship between action, sensation, rhythm and response allows AORTER to feel less like an external machine and more like an extension of the body.
When arms, shoulders or backs are being spent holding instead of controlling, the attachment can be configured around the task: through the limbs, directly to the equipment or across both. The objective stays the same: share concentrated demand, preserve strength for steering, manoeuvring and finishing the work, while reducing musculoskeletal injury.
Select a position to compare how the shoulder exits can route support toward the hands, wrists or an attached load.
Two taut tethers terminate at the supported load so the hands can steer, carry and reposition it through the configured range.
Wherever the continuous cord terminates, the pathway responds to that working end. It may finish at the load, both hands or one working arm, allowing the tether to follow the movement while carrying tension through the same bilateral route. Every interchangeable pathway is configured around the task, attachment, load and working range.
Terminate the pathway at the object and the load itself becomes the working end. A configured tool or object can remain supported while the hands release, regrip or manage another part of the task.
Tools · instruments · trays · tower work · carried equipment · performance gear
Terminate the pathway at the hands or wrists and both arms remain inside the bilateral route. The tether follows lifting, carrying, alignment and positioning while the wearer remains responsible for the movement.
Material handling · assembly · landscaping · rehabilitation · sport · general task support
Terminate both tether ends around one arm and the bilateral route can be redirected toward a primary side, sustained hold or professionally directed return-to-work pathway.
Recovery · shield or tool support · side-impact drilling · gardening · asymmetric task development
The same workday can demand a prolonged hold, rapid task changes and continuous material handling. AORTER configurations are assessed around how often the load moves, how long it is held and how quickly the user must transition.
Time under tension does not have to begin with a heavy object. A lighter tool held, guided or stabilized for hours can create its own sustained arm demand. AORTER can be configured around lighter-duty as well as heavier-duty work when the tether path remains clear and the user must stay in control.
If you hold your arm or a tool in position for a specific task, bring it to us.We can help determine whether AORTER can carry part of that demand.
AORTER CORE is our flagship unit.
AORTER CRANE is our heavy-duty workhorse.
AORTER CUSTOM is built for solving unique workflows.

AORTER excels at industrial support pathways for lifting, steering, tool handling and precision work. The result is measured where the work is felt: fatigue, control, task continuity and workflow fit.
Lorem ipsum dolor sit amet, consectetur adipiscing elit.Industry testimonial · placeholder
The attachment determines where support enters the task. Arm tethering shares demand while the tooling expert keeps the equipment in hand. Direct tool tethering moves support to the equipment itself, allowing a configured tool to remain suspended when the hands release it. Hybrid routing combines both. The pathway changes with the workflow without asking the operator to surrender steering, reach or control.
The arms and held object remain one moving mass. AORTER applies assistance through the limbs, reducing the residual demand the tooling expert must carry.
The tether connects to the equipment. Within the configured support range, the tool can remain suspended while the expert releases, regrips or changes position.
Arm and tool attachments can be combined around the workflow when the task requires both limb assistance and secured equipment.
Arm-to-arm tethering supports bilateral lifting, carrying, aligning and placement as the load moves from below the waist toward the upper chest. The pathway follows multi-plane movement instead of restricting the user to one fixed lift.
Reduce the cost of inverted grip. Awkward polyaxial work and one-sided loads can force the forearm into sustained rotation while the hand maintains control. A configured arm or direct-tool tether can support part of the mass so the expert can reposition the grip without abandoning the task.
Build it into your workflow. Power-tool manufacturers, PPE and safety suppliers, industrial distributors, ergonomics teams and employers can work directly with AORTE on demonstrations, attachments, distribution and task-specific configurations.
When vibration, reach and long-duration handling collide, professional lawn care finally has support that moves with the operator. Powered equipment stays mobile, steerable and under control through the work.

AORTER takes the load of trimmers, blowers, weed eaters, powered pruning tools, hedging equipment and arborist equipment through changing angles while the user continues steering and positioning the work. It creates continuous follow-through without interrupting the workflow. Direct attachment supports the tool itself, creating a mobile suspension point instead of asking the arms to hold its full weight between movements.
Connect support to the equipment when tool weight, vibration and time under tension accumulate.
Maintain reach, sweep, trim and repositioning through a changing outdoor workflow.
Long-handled tools turn reach into time under tension. Shovels, rakes, window-cleaning poles, sprayers and similar equipment can be supported without a motorized tool interface, using arm-to-arm, arm-to-tool or tool-to-tool routing selected around the movement the job already requires.
When our lives depend on the knowledge and precision of another person, their hands and arms deserve every mechanical advantage available. AORTER can stabilize the limbs across multiple working ranges for surgery, patient handling and other precision-based applications.
Lorem ipsum dolor sit amet, consectetur adipiscing elit.Clinical testimonial · placeholder
Stationary clinical workflows can create prolonged time under tension even when the carried load is small. AORTER development pathways support sustained arm positioning, controlled equipment placement and management of tool vibration where precision matters.
Support the arms through prolonged stationary procedures without fixing them to one plane.
Assist controlled placement and handling while the clinician retains direct movement control.
Clinical collaboration. Hospitals, surgical teams, occupational-health departments and medical-device partners can work with AORTE to define a procedure, measure time under tension and develop a purpose-fit support pathway.
Care work cannot become less human just because support is added. Caregivers, nurses and porters still have to move between rooms, beds, units and homes, change direction and respond to another person in real time. Mobile configurations can assist repositioning, rolling, stretcher work and equipment handling while preserving that freedom.
When mission equipment consumes the arms, it also consumes response capacity. AORTER supports the load before fatigue takes control, preserving movement, positioning and readiness for first responders and the soldiers who protect our country.
This belongs with the Special Forces.Colonel and Base Commander
Mobile assistance can support fire hoses, stretchers, breaching tools, heavy rescue equipment and casualty movement while the responder retains steering and control. Modular quick-release pathways can shift support from approved equipment to a limb interface when the response changes, including using a stronger limb to assist a newly dependent arm or leg during extraction.
Response time matters most when the load is already in the way. Purpose-fit tethering can support protective shields, breaching equipment, non-lethal equipment, field logistics and other approved loads while preserving rapid repositioning. Public-safety and Defence integration requires task-specific assessment, validation and authorization.

Explore Rescue + Defence R&DOriginally conceived as a space-fitness system, the KRA uses balanced resistance and bilateral coordination around a 50/50 equilibrium state. That same mechanical principle can support professional sport conditioning, AgeTech, accessibility and professionally directed rehabilitation.
Lorem ipsum dolor sit amet, consectetur adipiscing elit.Sports + rehabilitation testimonial · placeholder
AORTER was first conceived as a force-output system for boxing and gravity-invariant space applications. An athlete, for example, still moves real mass: the arms, the wearable and any attached training equipment. The bilateral mechanism adds configurable tension to that moving mass without reconfiguring a weighted vest or anchoring the athlete to a cable station.
Add mobile resistance through the punch, return, guard and footwork while preserving the athlete’s freedom to move.
Configure upper- and lower-limb tethers around stride, arm drive, acceleration and coordinated force output. Hiking and cross-country applications can add upper-body resistance, support carried equipment or enable shadow-form conditioning in the off-season.
Explore supported cameras, telescopes, binoculars and field-observation equipment through steadier carrying, positioning and movement measurement.
Resistance travels with the user for walking, jogging, controlled movement and general conditioning. Outward movement creates a bilateral challenge while inward assistance can support the return pathway. Configurable assistance and resistance can support progressive movement and professionally directed rehabilitation.
Research invitation. Hospitals, rehabilitation programs, clinicians and human-performance laboratories can work with AORTE on gait, bilateral coordination, upper-limb support and professionally supervised movement research.

Measure before ordering. These waist ranges guide standard sizing. Shoulder width, chest and torso fit also determine whether the physical frame and support structure will suit you. If your waist falls in both ranges, our team will help select the frame.
Prepare your measurements. Tell us your height, intended task and the clothing or protective equipment you will wear with AORTER. Measure your actual body circumference around the intended belt position over that clothing, keeping the tape level and comfortably snug. Do not use the size printed on your pants. Send the measurement in inches or centimetres.
Check your back length. The current standard frame is intended for an approximate 17–24-inch back-length range. Measure vertically from the base of the neck, where the upper frame will sit, to the intended waist-belt position. This is a preliminary compatibility check, not a substitute for confirmation by our team.
Check the upper-frame opening. The current opening between the shoulder structures is approximately 8 inches wide. Measure the widest body or protective-equipment profile that must pass through that opening while putting the unit on. This is a straight-line clearance measurement—not neck circumference—and a measurement equal to the full 8-inch opening is not automatically an acceptable fit. Our team must confirm safe clearance before an order proceeds.
Confirm the frame with us. Before you order, we can provide the relevant physical frame dimensions and guide your chest, shoulder-width and torso measurements. Our team will confirm neck and shoulder clearance, fit, attachment position and working range. CRANE height is configured relative to the shoulder and eye level.
Need a larger or specialized frame? Standard models are limited by their physical framing and support structure. Larger shoulders, waist measurements outside these ranges, or specialized fleet requirements may need tailored development through AORTER CUSTOM. Contact us with your requirements, particularly for fleet or industrial orders, so we can assess feasibility and quote the work.
We are a small Canadian business and will work with you to get the fit right before you order. Custom sizing is assessed individually and is subject to an agreed configuration, price and development schedule.
