I first stumbled across these researchers in 2016 when their project was known as “Wearable Lower Limb Anthropomorphic Exoskeleton (WLLAE).” In my January 20, 2016 posting, “#BCTECH: being at the Summit (Jan. 18-19, 2016),” an event put on by the province of British Columbia (BC, Canada) and the BC Innovation Council (BCIC), I visited a number of booths and talks at the #BC TECH Summit and had this to say about WLLAE,

“The Wearable Lower Limb Anthropomorphic Exoskeleton (WLLAE) – a lightweight, battery-operated and ergonomic robotic system to help those with mobility issues improve their lives. The exoskeleton features joints and links that correspond to those of a human body and sync with motion. SFU has designed, manufactured and tested a proof-of-concept prototype and the current version can mimic all the motions of hip joints.” The researchers (Siamak Arzanpour and Edward Park) pointed out that the ability to mimic all the motions of the hip is a big difference between their system and others which only allow the leg to move forward or back. They rushed the last couple of months to get this system ready for the Summit. In fact, they received their patent for the system the night before (Jan. 17, 2016) the Summit opened.

…

Unfortunately, there aren’t any pictures of WLLAE yet and the proof-of-concept version may differ significantly from the final version. This system could be used to help people regain movement (paralysis/frail seniors) and I believe there’s a possibility it could be used to enhance human performance (soldiers/athletes). The researchers still have some significant hoops to jump before getting to the human clinical trial stage. They need to refine their apparatus, ensure that it can be safely operated, and further develop the interface between human and machine. I believe WLLAE is considered a neuroprosthetic device. While it’s not a fake leg or arm, it enables movement (prosthetic) and it operates on brain waves (neuro). It’s a very exciting area of research, consequently, there’s a lot of international competition. [ETA January 3, 2024: I’m pretty sure I got the neuroprosthetic part wrong]

Time moved on and there was a name change and then there was this November 10, 2023 article by Jeremy Hainsworth for the Vancouver is Awesome website,

Vancouver-based fashion designer Chloe Angus thought she’d be in a wheelchair for the rest of her life after being diagnosed with an inoperable benign tumour in her spinal cord in 2015, resulting in permanent loss of mobility in her legs.

Now, however, she’s been using a state-of-the-art robotic exoskeleton known as XoMotion that can help physically disabled people self-balance, walk, sidestep, climb stairs and crouch.

“The first time I walked with the exoskeleton was a jaw-dropping experience,” said Angus. “After all these years, the exoskeleton let me stand up and walk on my own without falling. I felt like myself again.”

She added the exoskeleton has the potential to completely change the world for people with motion disabilities.

XoMotion is the result of a decade of research and the product of a Simon Fraser University spinoff company, Human in Motion Robotics (HMR) Inc. It’s the brainchild of professors Siamak Arzanpour and Edward Park.

Arzanpour and Park, both researchers in the Burnaby-based university’s School of Mechatronic Systems Engineering, began work on the device in 2014. They had a vision to enhance exoskeleton technology and empower individuals with mobility challenges to have more options for movement.

“We felt that there was an immediate need to help people with motion disabilities to walk again, with a full range of motion. At the time, exoskeletons could only walk forward. That was the only motion possible,” Arzanpour said.

A November 15, 2023 article (with an embedded video) by Amy Judd & Alissa Thibault for Global News (television) highlights Alexander’s story,

…

SFU professors Siamak Arzanpour and Edward Park wanted to help people with motion disabilities to walk freely, naturally and independently.

The exoskeleton [XoMotion] is now the most advanced of its kind in the world.

Chloe Angus, who lost her mobility in her legs in 2015, now works for the team.

She said the exoskeleton makes her feel like herself again.

…

She was diagnosed with an inoperable benign tumor in her spinal cord in 2015 which resulted in a sudden and permanent loss of mobility in her legs. At the time, doctors told Angus that she would need a wheelchair to move for the rest of her life.

Now she is part of the project and defying all odds.

“After all these years, the exoskeleton let me stand up and walk on my own without falling. I felt like myself again.”

There’s a bit more information in the November 8, 2023 Simon Fraser University (SFU) news release (which has the same embedded video as the Global News article) by Ray Sharma,

The state-of-the-art robotic exoskeleton known as XoMotion is the result of a decade of research and the product of an SFU spin off company, Human in Motion Robotics (HMR) Inc. The company has recently garnered millions in investment, an overseas partnership and a suite of new offices in Vancouver.

XoMotion allows individuals with mobility challenges to stand up and walk on their own, without additional support. When in use, XoMotion maintains its stability and simultaneously encompasses all the ranges of motion and degrees of freedom needed for users to self-balance, walk, sidestep, climb stairs, crouch, and more. 

Sensors within the lower-limb exoskeleton mimic the human body’s sense of logic to identify structures along the path, and in-turn, generate a fully balanced motion.

SFU professors Siamak Arzanpour and Edward Park, both researchers in the School of Mechatronic Systems Engineering, began work on the device in 2014 with a vision to enhance exoskeleton technology and empower individuals with mobility challenges to have more options for movement. 

“We felt that there was an immediate need to help people with motion disabilities to walk again, with a full range of motion. At the time, exoskeletons could only walk forward. That was the only motion possible,” says Arzanpour. 

The SFU professors, who first met in 2001 as graduate students at the University of Toronto, co-founded HMR in 2016, bringing together a group of students, end-users, therapists, and organizations to build upon the exoskeleton. Currently, 70 per cent of HMR employees are SFU graduates. 

…

In recent years, HMR has garnered multiple streams of investment, including a contract with Innovative Solutions Canada, and $10 million in funding during their Series A round in May, including an $8 million investment and strategic partnership from Beno TNR, a prominent Korean technology investment firm.
