Sumbu has announced its Exo-S3 line of dual-vector exoskeletons designed for the general public: the Exo-S3, Exo-S3 Pro and Exo-S3 Ultra.
The announcement was made at the CES 2026 event in Las Vegas.
The series is the world’s first commercially available dual-vector exoskeleton designed to support human movement across real-world terrain. This release establishes a new market for lightweight, AI-powered wearable mobility products.
The Exo-S3 ($1,199) is designed for daily mobility support, and provides lower-limb muscle strength primarily for domestic and urban environments. It is intended to be an accessible, cost-effective entry point to wearable mobility robotics.
The Exo-S3 Pro ($1,499) is for active injury prevention during intense activities and outdoor endurance athletes looking to minimise energy expenditure while reducing muscle soreness and joint fatigue.
The Exo-S3 Ultra ($1,999) is built for outdoor explorers and professionals, and optimised for maximum battery life, providing extended mobility support.
“Our human-centric design approach means Sumbu’s users now have a consumer-grade exoskeleton option that adapts to their needs,” said Martin Hsu, founder and CEO at Sumbu.
“The dual-vector drive means their exoskeleton automatically adjusts between power modes for uphill climbs, using stairs, and cycling.”
Using intelligent assistance to support users’ legs and minimize physical, the Exo-S3 series features a dual-vector power design, and are ergonomically engineered to boost movement efficiency by 20% – reducing fatigue for users. They also analyse shifts in users’ posture, and can automatically switch user movement modes.
The unites have an automotive-grade energy cell, a high-capacity EV-grade battery for extended range and performance, as well as a light-weight, ergonomic design. The exoskeletons also are dust-tight and water-resistant to ensure reliability against the elements.
The Exo-S3 series will be available for purchase in June, 2026 at www.sumbu.tech
