A Bengaluru Startup Uses Cane To Build Prosthetic Legs 

Cane is usually used to build lightweight furniture. Robotics engineer Arun Cherian makes cost-effective prosthetic legs out of it.

“It was curiosity. If cane is a spring and human leg is a spring, can I make a leg out of it? One thing led to an another,” said Cherian, 32.

The Journey

After a master’s degree in mechanical engineering from Columbia University, Cherian was pursuing a doctorate in mechanical engineering at Purdue University when he quit to start Rise Legs.

Cherian came up with the idea during a vacation back home and reached out to local artisans to find out if cane could indeed be used to make prosthetic legs. Once the craftsmen gave him the desired mould, the next step was to run mechanical trials, he told BloombergQuint in an interview.

“I ended up at the aerospace department of Indian Institute of Science (IISC) in Bengaluru and they had the right machines to test it. The results turned out to be far better than we had expected,” he added.

Rise Legs tied up with a non-governmental organisation (NGO) – Association of People With Disability – in Bengaluru and started making prototypes tested by volunteers from the association.

Arun Cherian, Founder, Rise LegsThey performed very well. An adult who had lost both the legs started kicking a football on the third day and went on to participate in a marathon.

Now, just over a year old and with 50 customers, Rise Legs can also customise prosthetic legs for the agile or those interested in sports.

“Prosthetic leg is not just a functional device but an extension of oneself and has a human element to it. We give the customer choices from having a naked structure to the one that is cosmetically covered and can be colour-matched to the skin tones or art works,” said Cherian.

The basic prosthetic leg costs Rs 4,000, far cheaper compared to the imported ones.

Rise Legs is now also working on developing wheelchairs for athletes and dancers.

Building An Ecosystem

People from as far as Australia, the West Indies, Uganda, Tunisia Mexico and Argentina are now reaching out, said Cherian. The aim is to grow in a phased manner and not at the cost of quality or after-sales, he said.

The objective, he said, was to build an ecosystem which would create awareness programmes to encourage users to take up activities like dancing, sports and fitness. He did concede though that its still hard to get doctors, cane artisans and amputees in the same room and get them to agree to do such a thing. But technology, said Cherian, talks for itself.
