The scientists use a radio transmitter and laptop to send commands to a receiver strapped to the rat's back which sends the signal to the implant.
In experiments, scientists managed to make the rodents run, turn and jump to command.
They even did an obstacle course involving running down a ladder, sprinting along a narrow ledge and squeezing through a hoop!
Scientist Dr Talwar reckons rats move more easily than robots can, which makes them perfect for the job.
And he says they could even train the rats to sniff out humans in rubble from earthquakes in the future.
