Wisson offers the patented Pliabot® technology, aiming at the above emerging needs of service robot applications, based on over a decade of scientific research. The core of the Pliabot® technology is the deployable structure pliable robotic muscles made from compliant materials, driven by pneumatics or hydraulics by the proprietary integrated motion control platform SlimDrive , paired with intelligent algorithmic platform SlimEngine . Together they form a groundbreaking paradigm of using compliant materials and fluidic drive to make safe, flexible, dexterous, lightweight, but strong and accurate robotic manipulators specifically for service robots.
Dexterity and flexibility. The Wisson Nimbo series manipulators were developed on the proprietary Pliabot® platform technology, following a completely distinctive core structure from conventional motor-based robotic manipulators. Instead of having multiple electric motors as joints, a series (often dozens) of flexible Pliabot® muscles form a network, parallelly into joints and sequentially into a manipulator. Kinematic redundancy could easily be achieved by stacking multiple joints each containing a corresponding number of muscles, allowing the manipulator to posture infinitely in space to reach a particular target of operation. With the muscles being compliant, the pneumatic actuation medium being compressible, and the kinematics being easily redundant, the resulting Nimbo pliable manipulators could have substantial dexterity equivalent to 6-to-7-DoF or above in rigid motor-driven manipulators, as well as inherent flexibility and impact safety even with controller failure or power off.

Ultra-high payload-to-weight ratio. Payload-to-weight ratio reflects a robot’s workload capacity per unit weight. Due to material-level and structure-level innovations, Wisson Nimbo series pliable manipulators could achieve over 1:1 payload-to-weight ratio, and topping at 3:1 maximum ratio at certain postures, approaching and surpassing human-arm capacities. Compared with Cobots (0.2-0.3:1 typically) and industrial manipulators (0.1:1 typically), the Nimbo pliable manipulators have substantially lower inertial but remarkably higher strength per unit weight, making them safe and energy-efficient by manifolds, ideal for mobile applications and close-proximity deployments with humans.
Interaction safety. The core to service robots is interaction. Interacting with people, environments, handling objects, performing inspections, cleaning various surfaces, service robots are destined to maneuver through complex environments handling random situations while frequently performing physical interactions. This calls for unconditional, guaranteed interaction safety under all circumstances. With the patented Pliabot® core technology, Wisson Nimbo pliable manipulators are based on flexible muscle structures paired with SlimEngine tri-loop advanced feedback control, ensuring timely and effective adaptation to both routine task interactions and unpredicted environmental incidences; and under the worst circumstances such as power down or mechanistic failure, the natural compliance from both the material and structure could ensure bottom-line safety to avoid damages to both the environment and the robot.
Outstanding environmental resistance. With virtually no seams and gaps typically seen in conventional motor-based rigid robots, Wisson Nimbo pliable manipulators could achieve a list of remarkable characteristics of high durability and environmental resistance: waterproof, moisture-proof, dustproof, radiation enhancement, corrosion resistance, ultra-high voltage resistance, etc. Designed to endure hash environments, Nimbo could be deployed outdoors for long-term operations. It could be particularly suitable for extreme environments such as dust, muddy, oil, electromagnetic radiation, hydraulic pressure, etc.
