Robotic weeder
Weeds lower crop yield to a great extent. Globally, a huge amount of herbicides are used to control weeds. But many of the herbicides are getting resistant to weeds. Moreover, the chemicals used as herbicides are very poisonous and harmful to human health, soil and environment. So, to control weeds more effectively and safely, scientists are working to develop some sustainable devices. Chemical-free, power-efficient robotic weeders have been developed for controlling weeds on crop fields, particularly of high value crops.
I think this technology should be introduced in Bangladesh and a modified version of the tool be released after proper designing and testing at agricultural research institutes.
