Several factors are responsible for reducing the crop productivity in worldwide. Among those factors, weed infestation is the major biotic constraint. Weed free condition during the critical period of crop weed competition is absolutely important for getting maximum yield. Weeds can be effectively managed by cultural, physical, chemical and biological methods. Among all those methods, hand weeding is an effective method of weed management. At the same time, increased labour wages and unavailability of agricultural labour during peak period of farm operations create pressure on researchers to find alternative method. Agricultural productivity is drastically decreasing in recent days mainly by delaying of timely operations due to labour unavailability. In this above context, chemical method is most effective and economical way of weed management. However, in recent days, excessive and inappropriate uses of chemical herbicides have gradually resulted in the wide problems of food and environmental contaminations. To manage the labour shortage, fasten the timely agricultural operation and precise application of agrochemicals is the new research area in agriculture. Over the past few years, several autonomous robotic technologies available for precise farming, manage the labour shortage, enhance the productivity and maintain the ecological balance. From the above review, it could be concluded that, introduction of artificial intelligence enabled agricultural robots is the potential and promising technique for mange the labour shortage, precise application of agrochemicals, speeding up the farm operations and increase the agricultural productivity. Undoubtly, this promising new generation technology will rule the modern agriculture in future.
