Low-cost Wheelchair with Robotic OS Developed by Kerala Students

A low-cost self-driving wheelchair developed by student researchers from Kerala, India. The wheelchair works on Robotic Operating System (ROS) and uses smartphone app for navigation.

A low-cost self-driving wheelchair named "Self-E" has been developed by the students of Amrita Vishwa Vidyapeetham, Kerala, India. It works on Robotic Operating System (ROS) and a smartphone app can be used for navigation.

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.

Robotic Wheelchair That can Now be Controlled With the User's Thoughts
US scientists have developed a machine that enables people to navigate a robotic wheelchair through their thoughts.

‘Users can have complete control over the wheelchair and do not need anyone's help. In case, patients have a problem using a smartphone, a friend or family member can use the Android app to transport them without being physically present to push the wheelchair.’

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.

Experimental Device Allows Paralyzed Individuals to Drive Wheelchair With the Flick of Their Tongue
A new study published in the journal Science Translational Medicine reports on the development of an experimental device.

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.

Ms Wheelchair New York Challenges Stereotypes
Ms. Wheelchair New York, Danielle Sheypuk has challenged stereotypes by proving that being disabled does not mean an absent social life.

"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.
