INFORMATION COLLECTED AND REQUIREMENTS INFERRED THROUGH BASIC SURVEY AND CUSTOMER INTERACTION:
| SERIAL NO. | OBSERVATION FROM LIT. SURVEY | IDENTIFIED REQUIREMENTS |
|---|---|---|
| 01. | All sorts of seeds need to be sown. | Robot should be capable of digging - holes of appropriate size, inserting - seeds one by one, filling - the hole, and, water - the seeds a little. |
| 02. | Wireless interaction with the robot is required from long distances without using any conventional remote control systems. | A gesture operated interactive system is suitable. |
| 03. | Robot should be economically feasible. | Cost of the device should not exceed Rs. 5000. |
| 04. | Robot should function in almost all terrains and environment. | Tracks and sprockets are needed instead of conventional wheels. |
| 05. | Prolonged and continuous operation is imminent. | Robot needs high battery and storage backup with tough and stable design. |
