Delhi kid with cerebral palsy inspires Iron Man-like suit for disabled
A Delhi child with cerebral palsy inspired the development of the first commercial exoskeleton for children with disabilities by two young Indo-Canadian engineers.
Manmeet Maggu and Rahul Udasi, both 26, who first met as students of mechatronics engineering at the University of Waterloo in Ontario, have set up the fledgling start-up, Trexo Robotics, to roll out the exoskeleton.
Maggu, born in Chandigarh, was influenced by the film Iron Man, and robotics was “a natural pull”. Initially, he looked at building an upper body exoskeleton as a side project during his years as an undergraduate.
However, his project turned personal after his Delhi-based brother Upinder’s son Praneit was diagnosed with cerebral palsy, a disease that greatly impairs motor function.
“I found out my nephew has cerebral palsy and he might never be able to walk. That really pushed us to consider our purpose as mechatronics engineers. And it became the motivation for us to build something for my nephew,” Maggu told Hindustan Times.
Maggu and Udasi bonded and roomed together and subsequently moved to Toronto, where Maggu completed an MBA at the University of Toronto’s Rotman School of Management while Udasi finished a Master’s in Robotics.
Now, with an office located in Mississauga, a suburb of Toronto, they will formally release the device this quarter.
The two decided to build the exoskeleton around a walker that the child used in India after spending last summer at Upinder’s house in Delhi .
“Last year we watched my nephew taking his first steps using our device. It was an incredibly proud moment. It was proof of concept that showed us this can work,” Maggu said.
“Our current version is the final version that children will be able to use, while there are some features we want to add in the future,” Udasi said.
The exoskeleton and the metal and plastic-based casings for the legs are powered by batteries and help ease the process of walking for a child.
“It’s a robotic device that can provide the child with rehabilitation and mobility,” Maggu said.
Often disabled children get tired easily and develop an awkward gait. ReX is intended to address that.
“Their body has never been taught the correct gait and they naturally fall into a lowest energy gait cycle. So, if one leg is weaker, you’re putting a lot more force on the other leg. When the exoskeleton is attached onto the walker, firstly it’s going to move your legs in the correct gait pattern. Secondly, you can adjust the parameters, so if one leg is weaker than the other, you can adjust the settings accordingly so that both of them are being exercised at the same time. Thirdly, it can actually help you walk longer periods. So, our vision is this can actually be a wheelchair replacement,” Maggu said.
The device will also allow such children to enjoy walking outdoors, which is problematic with walkers. At this time, they have prototypes of the device at clinics in the region, and have parents bring their children to their office to try them out.

A lot of the fabrication is being done in India, with Maggu’s brother involved in that process. Part of the effort is to make the device “cool” for the child, from the Iron Man vibe to “gamifying” it and having an interactive interface with a tablet which can also play the kid’s favourite cartoon to keep them “engaged”, Maggu said.
These are, in a sense, the first steps for the young company.
“We envision that our technology can be used to build a pathway for all those with disabilities, not just children but adults as well. We envision a future where exoskeletons can be used to augment any sort of human effort. That’s not restricted just to disability but even to increasing the ability of the individual as well,” Maggu said.
But for now, the focus is on getting the device in the market. And just as importantly, getting it to its prime inspiration as Maggu said, “I’m going to take it to Delhi for Praneit.”
A no-confidence motion tabled by the Opposition against Sri Lankan President Gotabaya Rajapaksa was defeated in Parliament on Tuesday, media reports said. The motion by Opposition Tamil National Alliance MP M A Sumanthiran to suspend Parliament's standing orders in order to debate an expression of displeasure over President Rajapaksa was defeated with 119 MPs voting against it, the Economy Next newspaper reported. Only 68 MPs voted in favour of the motion, it said.
The United States hopes “India would reconsider” its decision to ban wheat exports which “will make the current global food shortage even worse”, an envoy said on Monday amid concerns with no end in sight for the Ukraine war. Agriculture ministers from the Group of Seven nations on Saturday also emphasised that India's decision to ban wheat exports would worsen the global food shortage.
Canada will quickly ratify the membership of Finland and Sweden in the North Atlantic Treaty Organisation (Nato), as and when it has been approved. Speaking to reporters during the course of a teleconference from Brussels, Canada's Minister of Foreign Affairs Melanie Joly said such ratification has support from across party lines in Canada.
The United Kingdom on Tuesday accused Russia of being prepared for artillery use against inhabited civilian areas in Chernihiv, to the north of Ukraine's Capital, Kyiv, pointing to what it said was the 'scale of damage' to residential buildings caused by Moscow's troops in the region. The UK also projected that Moscow, in a bid to regain momentum in its advance in the Donbas area, would keep relying 'heavily' on massed artillery strikes.
