Cognition and R & D technology of micro robot

If there are robots that can work instead of humans , Then humans will be a lot easier , The current development has obviously begun to attack this field . Application of micro robot technology , It can make all kinds of aerospace measurements lighter , Household appliances such as tape recorders will also become smaller and more versatile , The TV screen can be made big and thin , The brightness of each point on it , It can be automatically controlled by a micro robot . Micro robots will also revolutionize Mechanics . The application fields of micro and ultra micro robots are very broad , It can be used for navigation 、 Agriculture 、 signal communication 、 Aerospace 、 Family and medical care .
for example : Drop thousands of micro robots to chew shellfish and moss on the bottom of the ship , It can save navigation energy . Scatter thousands of micro robots in the potato field , Let them kill pests , Make potatoes have a good harvest . Flying micro robot carries hygrometer and infrared sensor to fly in the field , When drought is found in farmland , It landed on the valve of the irrigation system , Transmit drought information to the sensor , Open the valve , To observe the environment where humans cannot reach , Store or transmit images . When the underground cable is broken , Let Cheng Gan crawl along the cable with tens of thousands of micro robots , When climbing to the broken head , Then put your hands on the front broken head , So the micro robot becomes a connecting wire , Permanently left on the cable .

Micro robots can clean 、 Repair the space telescope , Check the spacecraft heat shield , De icing the aircraft cover . If a large number of flying micro robots are deployed on other planets , The robot can send back all kinds of required information .
Micro robots can be released every night to keep watch near stores and warehouses , Prevent thieves from entering . The micro robot can also remove dust in the shelter of the house , Enter the internal inspection and maintenance of household appliances .
The evaluation criteria of micro robot capability are : intelligence , Refers to feeling and perception , Including memory operations 、 Compare 、 To identify 、 Judge 、 Decision making 、 Learning and logical reasoning ; function , Refers to variability 、 Universality or space occupancy, etc ; Physical energy , Finger force 、 Speed 、 Continuous operation capacity 、 reliability 、 Combination 、 Life, etc . therefore , It can be said that micro robot is a three-dimensional machine with biological function .

Robot navigation is a classical problem in the field of artificial intelligence , AI scientists have designed a series of algorithms , Hope to give unmanned cars 、 Robot spatial cognitive ability , Let the unmanned car 、 Robots can find their way in strange environments , Determine your position .
“ Unmanned aerial vehicle (uav) 、 Robot navigation requires a lot of expensive sensors , Huge computing resources are also needed in the process of travel , Even so, there is no guarantee that we can cope with emergencies in a dynamic environment . however , Mice can jump up and down with just a few peanuts , Escape the encirclement, pursuit and interception of natural enemies . How to make a driverless car 、 Robots adapt to dynamic environments like mice ？ Over the past half century , Researchers in the field of brain science have found that mammalian navigation is accomplished by the cooperation of a variety of nerve cells encoding spatial information .
The researchers first found a set of coding locations in the hippocampus of the mammalian brain “ Location cells ”, The cells can remember important locations such as nests and food sources . Then , A set of neural circuits responsible for spatial cognition was found near the hippocampus —— Entorhinal cortex , Among them “ Grid cells ” Be able to integrate another group with the function of representing the direction of motion “ Head toward the cell ”, To encode the location you have visited 、 Direction and distance . This dynamic mechanism can integrate multiple perceptual information , Make the driverless car 、 Robots build a set of cognitive maps in real time 、 It is possible to calculate the optimal probability of its own orientation and motion , And finally realize the autonomous navigation in the absence of external positioning information .
Another option for brain like intelligence or adult industrial intelligence . Current AI research , Focus on deep learning , Powered by computing power , Learn from big data , Complete speech recognition 、 Image understanding 、 Character recognition and other tasks .

Brain like intelligence provides a new possibility for the research of artificial intelligence . Brain like intelligence is based on the internal neural mechanism of the brain , To inspire new artificial intelligence algorithms and systems .“ Brain like intelligence is a feasible way to promote artificial intelligence to break through many bottlenecks at this stage .
in summary , In general , In the face of a strange environment , Unmanned vehicle 、 The robot needs to use sensors such as lidar to build the surrounding environment map . If there is no car 、 The robot needs to further complete tasks such as delivery and express delivery , You can plan a path from the beginning to the end according to the built map , Then move along the planned trajectory , And constantly reposition 、 Plan your route 、 Real time detection and obstacle avoidance , To ensure a smooth arrival at the end . however , The efficiency of these seemingly reasonable methods is far less than that of mammals such as mice .
