Kerala students develop low-cost self-driving wheelchair with Robotic OS
Coimbatore, July 4: Student researchers from the Amrita Vishwa Vidyapeetham here, have developed a low-cost self-driving wheelchair that works on Robotic Operating System (ROS) and can be navigated using a smartphone app.
Named "Self-E", the revolutionary wheelchair uses ROS to create a map of the surrounding space, along with static and dynamic obstacles, using a laser sensor and displays it through a smartphone app.
The user can then touch any point on the generated map and the wheelchair will drive to that place automatically without user intervention.
"The unique Self-E self-driving wheelchair now needs to be tested in different environments like hospitals and airports with patients and wheelchair users. We hope to commercialize the product," said Rajesh Kannan Megalingam, Assistant Professor at the varsity.
Self-E works by mapping the surrounding environment, including dynamic and static obstacles such as people, walls, pillars, tables, chairs, etc. using a laser sensor called LiDAR.
The map is automatically loaded onto an Android smartphone or tablet through a specially developed app.
Self-E's autonomous operation allows users to relax and sip a cup of coffee, read a newspaper or chat with friends as the wheelchair takes them to the desired destination point on its own.
"Users can have complete control over the wheelchair without anyone's help. On the other hand, if some patients have a problem in using a smartphone, a friend or family member or assistant can use the Android app to transport them without the need to physically push the wheelchair." said Chinta Ravi Teja, a student at the varsity.
Teja, along with Sarath Sreekanth and Akhil Raj have developed the Self-E wheelchair.

India to get first national security semiconductor fabrication plant
Wilmington (PTI): Under a transformative collaboration with the US, India will get a national security semiconductor fabrication plant that will produce chips for use in military hardware and next-generation telecommunications.
The India-US joint project was announced following talks between Prime Minister Narendra Modi and US President Joe Biden in Wilmington on Saturday.
A joint fact sheet on Modi-Biden talks said the two leaders "hailed" the semiconductor project as a "watershed arrangement".
It will be the first ever India-US semiconductor fabrication partnership.
It is the first time ever the US military has agreed to do a partnership for these highly-value technologies with India and it is a watershed moment as it is as significant as the civil nuclear deal, people familiar with the matter said.
"President Biden and Prime Minister Modi hailed a watershed arrangement to establish a new semiconductor fabrication plant focused on advanced sensing, communication, and power electronics for national security, next-generation telecommunications, and green energy applications," the fact sheet noted.
It said the "fab, which will be established with the objective of manufacturing infrared, gallium nitride and silicon carbide semiconductors, will be enabled by support from the India semiconductor mission as well as a strategic technology partnership between Bharat Semi, 3rdiTech, and the US Space Force."
The Fab becomes not only India’s first, but one of the world's first multi-material fabs for national security, the people cited above said.
The fact sheet said Modi and Biden praised combined efforts to facilitate resilient, secure, and sustainable semiconductor supply chains including through GlobalFoundries' (GF) creation of the GF Kolkata Power Center in Kolkata.
It said the project will enhance mutually beneficial linkages in research and development in chip manufacturing.
"The leaders welcomed steps our industry is taking to build safe, secure, and resilient supply chains for US, Indian, and international automotive markets, including through Ford Motor Company's submission of a Letter of Intent to utilize its Chennai plant to manufacture for export to global markets," the document said.
It said Modi and Biden commended ongoing efforts to build more expansive cooperation around 5G deployment and next-generation telecommunications.
This includes the US Agency for International Development's plans to expand the Asia Open RAN Academy with an initial USD 7 million investment to grow this workforce training initiative worldwide, including in South Asia with Indian institutions.
