METHODOLOGY
1. Studies- Conduct research through Internet, Books and Annual Report of
wheelchair companies
2. Discussion Group
- Brainstorming among the group members to decide the bestconcept for the motorized wheelchair
2. Prototyping- Build look alike models and obtained feedback about our concept
from expertise i.e lecturer and lab technician

LOOK LIKE MODEL
Figure 1: Initial Model
Insufficient strength properties of the materials- cardboard too soft- axels materials (wooden sticks)- arm rest (plastic tube with wooden sticks fills)
Too many wheel designs
Wheels size too small for intended load
Anthropometry miscalculations
