-GYRO
Gyro or mechanical gyrator is a vehicle which enables easy and safe transport of the differently abled and aged citizens. There by bringing them to mainstream of the society.
Technology in locomotion and mobility for the differently abled has progressed worldwide, but India continues to use antiquated tricycles and wheelchairs as mobility devices.
The project serves as a helping hand for differently abled since they are confined to their own bed due to insufficient technological advancements. GYRO tries to eliminate all the existing difficulties faced in using conventional mobility systems.
For solving the mobility problem the vehicle should process the following characteristics.
1. Able to control with least effort;using one hand
2. Convertible seating arrangement
3. Minimum turning radius
4. Better driving ergonomics
5. Safe
Basic concepts were created to incorporate the basic functionality of the vehicle. Different versions of sketches were explored and from that a few concepts were selected for further modelling.
After selecting the final concept sketch detailed system level design and detailed design was carried out. And the CAD-model of the vehicle is prepared using Solidworks.
Structural analysis of the critical components(gear,shaft and cross member respectively) were carried out and the dimensions and material specifications of the same were optimized.
Prototype of the proposed concept was made and it was taken for testing. All the component optimization and specifications were accommodated in the design.
Rim of 28 inch diameter was purchased without spokes. The load bearing members used were two MS steel bars of diameter equal to that of the rim. Since the steel rimes were inappropriate for welding ,angle plates were bolted to the rims. The two load bearing members where then crossed and welded to the angle plates. Wheels where centered by using the compass made by using two bolts and a rectangular cross section member.(insert picture of the compass) The bolts were bolted at a distance equal to that of the radius of the rim. Initially a centre was approximated on the MS bar. It is then punched. Bolt on one end was fixed on the approximate centre and the compass was rotated about that centre. The centre was adjusted back and forth in order to find the exact centre of the rim. Similarly centre is found for the other rim. Small hole is made at the exact centre by a drilling machine for the later fabrication works.
