Abstract
“Robot" as an "apparently human automation, intelligent but impersonal machine..." A ratbot or roborat is a rat controlled through implants in its brain.Guided rats controlled through implants in their brains could one day be used to search for landmines or buried victims of earthquakes, scientists say. An extraordinary experiment has seen researchers steering five rodents - so-called ratbots - through an obstacle course by remote control. Writing in the journal Nature, the scientists say the ratbots could reach places inaccessible to humans or machines. "One can think of the guided rat as a very good robot platform capable of traversing terrain that modern robots are unable to do," Dr Talwar said The rodents in the first experiment wore a small electronics backpack that linked to electrodes in their brains. They received radio commands from a laptop that would stimulate sensations in their whiskers and reward/pleasure receptors to manipulate them into following pre-programmed routes. Some researchers propose using them to search for landmines or buried victims of earthquakes, as they can much more efficiently scout such areas than human rescuers or existing robots.The rats also quickly learnt to associate the stimulation of their brains' reward centres with simply walking forwards, even if this involved climbing or descending ladders or steps, or moving into the centre of a brightly lit room - something that most rats would avoid.
