Vision and Conceptualization
In 2020, a Mechanical Engineering student at MIT sought to bridge the gap between his technical expertise and his passion for trekking the rugged terrain of the Colorado mountains. During the development of his graduation project, he conducted extensive research into performance-enhancing gear. While traditional equipment like trekking poles and specialized footwear offered marginal benefits, he identified a significant opportunity in exoskeleton technology.
Historically, exoskeletons were primarily confined to the medical rehabilitation sector, characterized by high costs and limited functionality for able-bodied users. His vision was to redefine this technology by integrating advanced sensors capable of recognizing diverse terrain and gait postures, allowing a high-torque motor to adjust dynamically and reduce physical exertion for hikers.
Engineering Excellence and Collaborative Development
The project’s rapid transition from concept to prototype was fueled by a multidisciplinary team, including experts in Electrical Engineering. This collaboration allowed the team to overcome complex R&D hurdles, such as developing proprietary circuit boards and calibrating sensor-motor feedback loops under diverse environmental conditions.
The final design features a sophisticated, brace-like structure with a centrally located motor at the knee, ensuring unrestricted movement and easy folding. To facilitate seamless human-machine interaction, four high-precision sensors are strategically positioned to monitor distance, force, and spatial orientation in real-time.
The Power Solution: High-Discharge Industrial Battery Integration
To meet the demanding requirements of the 1000W motor—which requires powerful, short-burst currents to drive assisted movements—a specialized power system was required.
We collaborated with the team to design a customized battery solution tailored for high-performance industrial applications:
-
Cell Selection: The Sony VTC6 18650 was selected as the preferred cell due to its exceptional energy density and ability to handle 40A high-discharge pulses.
-
Ruggedized Hardware: We engineered a compact, IPX7 waterproof battery housing equipped with a secure 5-pin output port, ensuring reliability in unpredictable outdoor environments.
-
Smart Monitoring: The pack features integrated communication protocols, enabling users to monitor State of Charge (SOC) and estimated remaining runtime via a mobile app.
-
Rapid Charging: To maximize uptime, we developed a series of ultra-compact fast chargers, facilitating quick turnaround times for multi-day expeditions.
Market Success and the Path to Medical Certification
The initial prototype was met with high acclaim within the climbing community, receiving a 75% positive feedback rate. This invaluable user data allowed the team to refine the system for mass production. By 2022, the project achieved significant commercial success, securing over 10,000 pre-orders through its official platform.
Looking ahead, the team is expanding into the clinical and medical equipment sector. To meet the rigorous safety standards required for healthcare applications, the next generation of devices is currently undergoing comprehensive certification processes, including FDA, IEC, and UL compliance. This evolution marks the transition of the project from a niche hiking aid to a world-class assistive technology.
