The document describes a hand gesture-controlled wheelchair that operates through tilting hand movements to navigate forward, backward, and turn. It outlines the hardware and software requirements, along with the advantages such as ease of design and low cost, and disadvantages like power failure risks. Future developments include adding obstacle detection sensors and increasing power capacity.

7. ADVANTAGES &
DISADVANTAGES

8. ADVANTAGES
0 It is easy to design and manufacture as all the
components are easily available.
0 It is portable and hence can be placed anywhere.
0 It has low cost of manufacturing
0 The C can be reprogrammed if any modification is
required.
0 Due to wireless communication data rate is faster .
0 Wireless makes ease of operation.
0 No need of lengthy wires.
0 Power consumption is less.

9. DISADVANTAGES
0 If power supply fails system won’t work
0 Failure of device/components may have dire
consequences, fatal accidents can occur.

10. FUTURE DEVELOPMENTS
0 We can also add an obstacle detection sensor in the
wheel chair.
0 Increase power capacity.
