Improved pedal cycle rickshaw(IMPRA)
IMPRA has three-speed gears, reduced length of long chain drives, back-wheel shaft braking, better suspension and less aerodynamic drag than the existing ones.
The weight of IMPRA is 85 kg compared to 90–95 kg of the existing rickshaws. Its life is estimated to be between 7 and 10 years.
Motor-assisted pedal cycle rickshaw(MAPRA)
It is a rickshaw with a Motor attached to it so that it can assist their pedaling whenever they(rickshaw puller) experienced load, or while going uphill. The extra power may also allow the rickshaw pullers to ply the rickshaw for longer distances and thus increase their earnings per day.
With increased pollution in cities of India and various courts passing strictures on polluting vehicles, there is a need to introduce environmentally sound transport systems on the roads.In addition to the CNG-powered buses and three-wheelers, quite a number of major companies have introduced electric-powered three-wheelers. However, all these vehicles are expensive, with their prices ranging from Rs 2.75 to 4.28 lakhs. I therefore feel that small transport systems like rickshaws are more suited for electric vehicle development. Thus reasonably priced, small size, indigenous batteries have been used to power the MAPRA.
What will it take for your project to be successful over the next three years? Please address each year separately, if possible.
We feel that the following technological and policy issues need to be looked at for the MAPRA to spread and become a viable transport system in India.
1. There is need to develop a low cost sensor/controller for sensing the load of the MAPRA and to switch on and off the motor accordingly.
2. There is need to develop a low cost battery charger based on switch-mode power supply (SMPS) technology, which should be rugged and could be mounted on the MAPRA, so that the batteries could be charged anywhere. Presently, such rugged and low-cost battery chargers are not available.
What would prevent your project from being a success?
Nothing can prevent this project from being a success beacuse it will solve prolem of employment, pollution and environment.
