Prototype component details:Interview with representative
– Thin iron sheets/aluminum as a base material
– Standard (global) wheelchair dimensions used for prototype design
– Can be driven using both a throttle and torque sensor pedal
– Solar charger kit required to charge the battery bank.
Electrical or mechanical workshops with professional and expertise mechanics are capable of providing technical support to any wheelchair malfunction. If any motor or battery malfunction occurs, the user will have to take the wheelchair to the after sales service center or to the manufacturer.Interview with representative
Unknown if components are replaceable or designed specifically for the wheelchair.
The wheelchair is expected to have a lifetime of 36 months with everyday outdoor use. The warranty of the wheelchair depends on the warranty of the electrical components within the wheelchair.Interview with representative
Battery: 2 years
Hub motor: 1 year
Service warranty: 1 year

None. CARC will begin certifying the wheelchair after the end design is developed.Interview with representative
Laboratory testing was conducted on various components of the prototype wheelchair in the CARC laboratory at BRAC University. Field testing is ongoing by the Center for the Rehabilitation of the Paralyzed patients and doctors.Interview with representative
This product was featured in an article on Engineering for Change’s website, where the designers and company representatives answered questions about the wheelchair and its plans for the future. The wheelchair is currently being developed, and will soon launch its second edition with edits and modifications determined from field testing and feedback.
