Sarcomere Dynamics

Sarcomere Dynamics Inc. is a Canadian robotics company based in St. Albert, Alberta that designs compact, high-dexterity robotic hands sold under the ARTUS brand. Its flagship product, the ARTUS Lite, is a five-fingered, roughly human-sized dexterous hand with 20 degrees of freedom that can grasp, pinch, and manipulate objects and bolt onto most industrial robot arms with little modification.^[1][7] The company grew out of a University of British Columbia (UBC) engineering design project that set out to build an affordable upper-limb prosthetic, and its name refers to the sarcomere, the contractile unit of skeletal muscle, reflecting an actuation approach that imitates muscle using bundles of shape memory alloy (SMA) wire.^[2][4] Sarcomere positions the ARTUS family as a lower-cost alternative to established research hands for industrial automation, teleoperation, and eventually prosthetics.^[1][5] It should not be confused with Sarcos, a separate United States exoskeleton and robotics firm; a widely shared robotics infographic mislabeled the ARTUS Lite as a "Sarcos" product.

History and origins

Sarcomere Dynamics traces its origin to an undergraduate engineering design project at the University of British Columbia. Avtar Mandaher, who completed a bachelor's degree in integrated engineering at UBC in 2019, led a student team that built a prosthetic hand actuated by shape memory materials, work that won a departmental award for best design project.^[2] The goal was a more sophisticated yet economical upper-limb prosthetic: high-end myoelectric prosthetic hands can cost on the order of tens of thousands of dollars, and the team wanted to bring that capability down in price.^[2][13]

The startup was formally founded in 2021 and passed through the entrepreneurship@UBC accelerator that year, later completing the HATCH Builder program (2022) and being named to New Ventures BC's Top 26 Spotlight.^[4][3] An early demonstrator hand weighed about 300 grams and delivered roughly 11 degrees of freedom, close to half the articulation of a human hand, which is often described as having on the order of 25 degrees of freedom.^[4]

The company then pivoted from prosthetics toward industrial robotics. As Avtar Mandaher later described it, the higher-dexterity hands the team built proved difficult for amputees to control, while industrial customers facing labor shortages showed strong interest in a compact, capable end-effector: "wherever there's a human hand that is required to do dexterous work," there was a potential application.^[1][2] The company has said it intends to return to prosthetics once the underlying hand technology matures, targeting a prosthetic priced well below existing devices.^[2][13]

Early corporate activity was centered in British Columbia (the company appeared at events in Abbotsford, and 2023 coverage placed it there), but Sarcomere is now headquartered in St. Albert, Alberta, in the Edmonton metropolitan area, where it has become a visible member of the region's advanced-manufacturing and defence technology community.^[3][6][12] The three founders are members of the Mandaher family: Avtar Mandaher serves as chief technology officer, Harpal Mandaher (a 32-year veteran of the Canadian Armed Forces) as chief executive officer, and Nancy Mandaher (a retired nurse) as chief operating officer.^[1]

The ARTUS and ARTUS Lite hands

Sarcomere develops a portfolio of robotic hands offered in 10, 20, and 24 degree-of-freedom configurations, meant to scale from simple pick-and-place grippers up to hands capable of human-like parts assembly.^[1] All models are designed to be compatible with one another, so that machine-learning, kinematic, and control data developed on one hand can be transferred to a newer model.^[5][9] The best-documented product is the ARTUS Lite, described by the company as its entry-level hand for "dull, dirty, and dangerous" tasks and marketed as an agnostic, universal end-effector that replaces fixed-function grippers.^[5]

The ARTUS Lite is a five-digit hand (a thumb plus four fingers) built to a human scale, with 20 degrees of freedom split into 16 actuated and 4 under-actuated joints across roughly 20 articulated joints.^[8][9] It is built from carbon fiber, aluminum, and silicone and weighs about 1.4 kg, with a footprint near 186 mm long by 80 mm wide.^[7][8] Sarcomere rates it for a payload of about 5 kg per hand, with custom options up to 20 kg on request, and a fingertip force near 1.5 kg; some trade coverage cites a working payload of 6 to 7 kg per hand.^[8][7][9] Open and close cycles run at roughly 1 Hz; a later Mark 7 revision has been quoted at about 0.9 Hz with 2 to 2.4 kg of fingertip force for delicate, precise manipulation.^[9] The hand's development has proceeded through numbered marks, including Mark 5 (initial release, late 2023) and Mark 6 (2024).^[6]

Actuation: a muscle-inspired approach

The company's name is a direct reference to its actuation concept. A sarcomere is the basic contractile unit of skeletal muscle, built from overlapping myosin and actin filaments that shorten by sliding past one another. Sarcomere Dynamics' hands use novel actuators based on shape memory alloy, a metal that contracts when heated and relaxes when cooled, arranged in a biomimetic fashion that echoes how natural sarcomeres and myofibrils bundle together, for example by placing an additional fiber at the center of a bundle of SMA wires.^[4] This "artificial muscle" approach is what lets the hands pack many actuated joints into a lightweight, compact package without the bulk of conventional motor-and-gearbox drives, and it underpins the company's central claim of near-human dexterity "at a fraction of the cost" of competing technologies.^[1][4] Sarcomere's shipping product datasheets describe the mechanism only as a proprietary actuator technology; the specific identification as shape memory alloy comes from the founders and from earlier coverage of the UBC prototype.^[2][4] The actuation hardware is supported on the back (dorsum) of the hand, a layout visible in product imagery.

Sensing, control, and teleoperation

Rather than relying on a skin of fingertip tactile sensors, the shipping ARTUS Lite uses internal sensing of finger-joint position and force, giving it real-time force feedback without external sensor hardware.^[5][8] Sarcomere describes the hand as "AI-ready," and it can be upgraded with integrated shear-force sensors in the fingertips for tasks that need finer contact sensing.^[9][10] The company has also said it is developing a full-surface artificial skin with a German sensor firm, which would extend tactile coverage beyond the fingertips; this remains a development effort rather than a shipping feature.^[13]

The hand is controlled through Sarcomere's software stack: a Python library (ArtusAPI, requiring Python 3.10 or later), a ROS 2 node for integration with the wider robotics ecosystem, and a graphical control interface.^[6] For teleoperation, ARTUS supports real-time position streaming and integrates with the MANUS haptic data glove, using a roughly one-for-one mapping so an operator's finger motions drive the robot hand directly; feedback can be relayed to the operator through the glove.^[6][10][13] Electrically and mechanically, the ARTUS Lite mounts on a standard ISO 9409-1-50-4-M6 robot flange and communicates over CANbus, RS485 serial, USB-C, or WiFi, running from a 24 V supply; the company advertises plug-and-play compatibility with major industrial arm brands including Universal Robots, FANUC, ABB, OMRON, and Hans Robot.^[8][6][10]

Applications and markets

Sarcomere aims the ARTUS hands at work "wherever there's a human hand" doing dexterous tasks, spanning industrial automation, teleoperation of remote or hazardous processes, and humanoid robot end-effectors.^[1][5] The company's own materials list pick-and-place automation in greenhouses, warehouses, and recycling; teleoperation for precise remote manipulation, including trials aimed at military and autonomous-systems use; and dexterous end-effectors for humanoid robots.^[5] Reported target sectors include biopharma, aerospace, nuclear, and advanced manufacturing, along with food packing, electronics assembly, and hazardous-materials handling.^[9][1]

The teleoperation and hazardous-environment angle is a recurring theme. Sarcomere has demonstrated the hands at the World Nuclear Exhibition and, in 2026, joined an Edmonton-region delegation at Eurosatory in Paris, one of the world's largest defence and security trade shows, positioning ARTUS for nuclear decommissioning, bomb disposal, chemical handling, and other tasks too dangerous for people.^[13][15] Because the hand is designed to serve as a general-purpose replacement for fixed-function grippers, Sarcomere also markets it to system integrators building general robotic cells rather than to a single vertical.^[5][10]

The prosthetics origin remains part of the company's stated roadmap. Sarcomere has framed the same core technology as a route to a much cheaper myoelectric bionic hand, citing a target price on the order of a few thousand dollars against a market where advanced prosthetic hands can cost tens of thousands.^[13][2]

Recognition and funding

Sarcomere Dynamics won first place in the Robotics category of the 16th Innovation World Cup (2025), an international competition for connected and embedded technologies, an award tied to the ARTUS Lite and its promise of human-like dexterity for automation, teleoperation, and hazardous-materials handling.^[11] The company has also been recognized through Canadian startup programs, including entrepreneurship@UBC, HATCH, and recognition in New Ventures BC's Top 26 Spotlight.^[4][3] It is a frequent exhibitor at major trade fairs, having shown the ARTUS Lite at Hannover Messe and, in 2025 and 2026, at events such as Computex and Innovex in Taipei as it pursued Asian manufacturing and supply-chain partnerships and embodied-AI collaborators.^[17][13][9]

Detailed financials are not publicly disclosed, and third-party startup databases give differing totals. Reporting on the Edmonton startup ecosystem listed Sarcomere Dynamics among notable 2025 funding rounds, citing roughly $13.8 million raised, while some investment databases record smaller cumulative figures; these numbers should be treated as approximate.^[14] Sarcomere is federally incorporated in Canada and operates from an office on St. Albert Trail in St. Albert, Alberta.^[16]

Not to be confused with Sarcos

Sarcomere Dynamics is unrelated to Sarcos (Sarcos Technology and Robotics Corporation), a United States company best known for powered exoskeletons such as the Guardian XO and for teleoperated robots. The two firms have similar-sounding names but different countries, products, and histories. The confusion appears to stem from a robotics infographic that incorrectly credited the ARTUS Lite to "Sarcos." The ARTUS and ARTUS Lite hands are products of Sarcomere Dynamics.

Limitations

Independent, peer-reviewed benchmarking of the ARTUS hands is limited; most specifications come from the company, its resellers, and trade coverage, and some figures (notably payload, which is variously quoted at about 5 kg or 6 to 7 kg per hand) differ between sources. Shape memory alloy actuation, while compact and lightweight, is generally slower than direct electric drives and depends on heating and cooling cycles, which can constrain actuation speed and thermal management; the roughly 1 Hz open-close rate is modest next to fast servo-driven grippers. The shipping ARTUS Lite relies on internal joint-level force sensing rather than dense fingertip tactile sensors, with fuller skin-like sensing still in development. As with most emerging dexterous hands, real-world autonomy still leans heavily on teleoperation, and the company's stated return to prosthetics, including regulatory clearance and clinical validation, remains a future goal rather than a shipped product.^[13][9]
