6. NeuroArm: the first robotic neurosurgeon
In 2008, a Canadian woman became the first person to have a robot's hands inside her head. Controlled by a neurosurgeon at a computer workstation, neuroArm worked for nine hours to remove a tumour from Paige Nickason's head. NeuroArm, developed at the University of Calgary, has a sense of touch, a necessity in brain surgery, where surgeons judge how to proceed by how soft the brain is. And for precision, the two robotic arms are peerless.
