The 'ultimate mosquito killer' uses lasers and AI — custom model trained to detect and lock lasers on these pests

A mosquito.

A computer vision and robotics expert has created and trained what he boasts is “the ultimate mosquito killer.” Steven Cheng shared details of his high-tech bug zapper project on social media. Key innovations here include the use of computer vision and deep learning technologies to detect and lock onto mosquitoes so the laser ‘artillery cannon’ could do its work.
