Aerial Robot is also commonly known as Unmanned Aerial Vehicle (UAV) or Drone. In this context, robot (Arial, Ground and Underwater) can play an important role. The knitting of information and modern electronic technology with agricultural production system to determine, analyze and manage the critical temporal and spatial factors of farm for maximizing profitability, sustainability and environmental protection is need of hour.
SMALL KNAPSACK MANUAL
The concept of transforming manual operated to battery assisted weeder was found satisfactory for wide row crops. The machine is gender-friendly with simple in design and technology and has potential to be adopted by small and hill farmers with reduced drudgery. A brushed DC motor of 250W powered by 24V-14Ah battery with sweep type weeding tool performed satisfactorily in the field for weeding operation up to 147N draft.The operators are to only guide the weeder up to 147N draft while they need to apply their muscle power beyond 147N to prevent slippage.The average field capacity with this machine was 0.0554 ha/h at walking speed of 2.52 km/h with 97.5% weeding efficiency. The developed machine consisted of brushed DC motor, DMSC, battery, power transmission system, drive-wheels, front wheels, frame and swinging handle. Mechatronics concept was incorporated in development of a battery-assisted four-wheel weeder for weeding operation in wide row (more than 30 cm) crops.
Mechanical methods of weeding are preferred over other methods of weed control because of their added advantages of simple construction, low cost and environmental friendly.
