LAS VEGAS—In a groundbreaking demonstration at CES 2026, the Dephy Sidekick robotic exoskeleton offered a glimpse into the future of personal mobility. As the first journalist to test this innovative device, I found myself both intrigued and impressed by its potential to transform everyday activities.
Developed by Dephy, the Sidekick is designed to assist with walking by lifting the heels with each step. Priced at $4,500, the device is set to begin shipping on January 25. The Sidekick features a proprietary shoe equipped with a carbon fiber plate, which connects to a battery-powered exoskeleton strapped to the calf. The setup process is remarkably quick, taking only about 15 seconds per leg.
How the Sidekick Works
Once activated, the Sidekick analyzes the user’s gait and provides a gentle, battery-assisted boost with each step. This technology is powered by a brushless electric motor, Inertial Measurement Unit (IMU) sensors, and a controller, all housed within the exoskeleton. A removable battery powers the motor, ensuring the device remains lightweight and unobtrusive.
“The calves are really the unsung heroes of mobility,” said Dephy CEO and Cofounder Luke Mooney. “This first product is targeting experiences—walking the dog, going to the store. We’re really just trying to help people move in the ways that they used to be able to.”
Design and User Experience
The Sidekick’s design is reminiscent of popular athletic footwear, such as Hoka sneakers, offering good arch support and comfort. Unlike other exoskeletons that attach to the hips or knees, the Sidekick’s calf attachment makes it less noticeable and more comfortable for extended use. During my trial, I wore the device around The Venetian lobby for about 20 minutes, experiencing a subtle yet supportive boost with each step.
Similar to e-bikes, the Sidekick offers multiple levels of assistance. On medium power, I encountered a few moments of instability, but overall, the sensation was one of enhanced support. A brief learning curve is involved as both the user and the device adapt to each other.
“There’s a low-level learning curve where you’re still adapting, and it’s adapting to you,” Mooney explained.
Implications for Mobility and Accessibility
The introduction of the Sidekick at CES 2026 represents a significant step forward in the field of assistive technology. By targeting everyday activities, Dephy aims to improve the quality of life for individuals who may struggle with mobility due to age, injury, or disability. The device’s unobtrusive design and ease of use could make it an attractive option for a wide range of users.
As the first product of its kind to hit the market, the Sidekick sets a precedent for future developments in wearable robotics. Its potential applications extend beyond personal use, with possibilities in rehabilitation and physical therapy settings.
The Road Ahead
As Dephy prepares to launch the Sidekick, the company is likely to face competition from other tech firms exploring similar innovations. However, the Sidekick’s unique design and focus on everyday mobility set it apart from existing products.
Looking ahead, the success of the Sidekick could pave the way for more advanced models, potentially incorporating features such as enhanced stability controls and increased battery life. As the technology evolves, it may become an integral part of daily life for those seeking to maintain their independence and mobility.
The Sidekick’s debut at CES 2026 marks the beginning of a new era in assistive technology, offering a promising glimpse into a future where mobility challenges are met with innovative solutions.
