We know that chairless-chairs like the Archelis are not a new technology thanks to Ray Hu at Core77.com has a phenomenal article on the 40-year history of the Chairless Chairs: Who Knew? The Wearable Chair Was Actually Invented 37 Years Ago. These types of exoskeletons are based on prior research going back many decades to allow people to sit in nearly any situation. The Archelis and similar devices have been recorded being used in factories, surgical rooms, and public transportation. It is designed to reduce fatigue from standing in place for too long.
While the concept may be old, the potential for ROI is there. As people get fatigued, our concentration on the task we may be performing decreases. Imagine a brain surgeon performing a delicate procedure for multiple hours standing over you. Would you want to have the surgeon pay undivided attention to you or have them think of how much their legs are starting to ache?
The design intent is for the Archelis to:
- Allow the user to work prolonged periods of time while standing without any burden on their legs & lower back
- Maintain freedom to walk and move while wearing the exoskeleton
- No battery or other energy source is required, this is a purely mechanical device
- To be worn on various body shapes with a simple adjustment
The different variations of the Archelis weigh between 5.07 lb to 5.95 lb (2.3 kg to 2.7 kg). It can accommodate users ranging from 4.9 to 6 feet in height (1.5 to 1.8 m) and up to 176 lb or 80 kg for the larger model.
The Archelis supports three modes of operations:
- Free Mode: Easier to walk than other modes, allows for the knees to bend freely and there are no restrictions to the legs. However, it does not support standing position.
- Archelis Mode: allows for walking and for body support with the knees slightly bent.
- Standing Mode: supports the body while standing. On the outside, it may appear like the user is just standing in place but the passive exoskeleton is actually supporting them.
At the start of 2021 the Archelis is both sold as a product and as a 12/24/36 month rental.
