An articulated robot is the type of robot that comes to mind when most people think about robots. Much like CNC mills, articulated robots are classified by the number of points of rotation or axes they have. The most common is the 6-axis articulated robot. There are also 4- and 7-axis units on the market. Flexibility, dexterity, and reach make articulated robots ideally suited for tasks that span non-parallel planes, such as machine tending.
Articulated robots can also easily reach into a machine tool compartment and under obstructions to gain access to a workpiece or even around an obstruction, in the case of a 7-axis robot. Sealed joints and protective sleeves allow articulated robots to excel in clean and dirty environments alike. The potential for mounting an articulated robot on any surface e. The sophistication of an articulated robot comes with a higher cost compared to other robot types with similar payloads.
And articulated robots are less suited than other types of robots for very high-speed applications due to their more complex kinematics and relatively higher component mass. Whilst it is true that invention of robots initially commenced with heavy focus on utilitarian use production or services , we cannot neglect the existence of cool entertainment robots!
These types of robots are widely accessible and available for public, contrast to others on this list. An example is a digital pet, Aibo the robotic dog that replaces real-life domestic pets. It is able to replicate many actions that provide owners with realistic experiences of owning a dog.
This can be a perfect alternative for those who would like company but have unfavourable circumstances e. As such, entertainment robots are not deemed as essential, but definitely forms an important part of robot development in the modern world for increasing quality of life for many.

Today, advanced robots are popping up everywhere. For that you can thank three technologies in particular: sensors, actuators, and AI. So, sensors. Machines that roll on sidewalks to deliver falafel can only navigate our world thanks in large part to the Darpa Grand Challenge, in which teams of roboticists cobbled together self-driving cars to race through the desert.
Their secret? Lidar, which shoots out lasers to build a 3-D map of the world. The ensuing private-sector race to develop self-driving cars has dramatically driven down the price of lidar, to the point that engineers can create perceptive robots on the relative cheap.
Lidar is often combined with something called machine vision—2-D or 3-D cameras that allow the robot to build an even better picture of its world. You know how Facebook automatically recognizes your mug and tags you in pictures? Same principle with robots.
Fancy algorithms allow them to pick out certain landmarks or objects. Sensors are what keep robots from smashing into things. Without actuators, robots would crumple like rag dolls. Even relatively simple robots like Roombas owe their existence to actuators.
Self-driving cars, too, are loaded with the things. Actuators are great for powering massive robot arms on a car assembly line, but a newish field, known as soft robotics, is devoted to creating actuators that operate on a whole new level. Unlike mule robots, soft robots are generally squishy, and use air or oil to get themselves moving. So for instance, one particular kind of robot muscle uses electrodes to squeeze a pouch of oil, expanding and contracting to tug on weights.
Unlike with bulky traditional actuators, you could stack a bunch of these to magnify the strength: A robot named Kengoro, for instance, moves with actuators that tug on cables, allowing the machine to do unsettlingly human maneuvers like pushups. At first, university robotics research teams struggled to get the machine to tackle the basic tasks of the original challenge and the finals round in , like turning valves and opening doors. But Boston Dynamics has since that time turned Atlas into a marvel that can do backflips , far outpacing other bipeds that still have a hard time walking.
Unlike the Terminator, though, it does not pack heat. Boston Dynamics has also begun leasing a quadruped robot called Spot, which can recover in unsettling fashion when humans kick or tug on it.
Robotics seems to be reaching an inflection point, where processing power and artificial intelligence are combining to truly ensmarten the machines. Seven robots you need to know Pointing the way to an android future. Grasping an object. Some of the hardest problems in robotics involve trying to replicate things that humans do easily. The goal? Creating a general purpose robot think C-3PO from Star Wars rather than specialised industrial machines.
Here are seven existing robots that point the way towards the humanoid robots of the future.
