Robots

Somewhere in the last few years, without a formal announcement, the age of robots simply started. Robots, autonomous and semi autonomous machines that sense, decide and act in the physical world, now hold jobs across the whole economy: humanoids running factory inspection lines and greeting car buyers in thirty countries, robot dogs patrolling substations through the night, delivery robots serving tens of thousands of restaurants and hotels, close to five million machines working the world's warehouses and cleaning fleets that verify their own work to an audit standard. What was demonstration is now deployment, measured in shipped units, order books and shifts covered.

Three forces converged to make it happen. Reinforcement learning cracked the control problems, balance, gait, grasping, that scripted engineering never solved, giving machines athletic recovery and dexterous touch. Foundation models gave them understanding, natural conversation, task planning and the ability to learn new work from demonstration in days. And mass manufacturing, led by makers shipping thousands of humanoids and tens of thousands of quadrupeds a year, collapsed prices from laboratory budgets to business cases, putting serious robots within reach of a school, a restaurant or a mid size factory.

This page is the field guide: every major robot type, from humanoids and quadrupeds to service, industrial and consumer machines, the brands that lead each, and the paths to buying them, with the complete range of robots for sale browsable through the robot catalog and organized by application in robot solutions.

The Major Types of Robots

Humanoid Robots

The defining category of the decade. Humanoid robots, machines in human form built for the world humans built, now ship at industrial volume: Unitree moved over 5,500 humanoids in a single year led by the G1, AgiBot has produced more than 15,000 robots across its acrobatic X2, athletic A3 and industrial G2 families, UBTECH's Walker S2 passed 1,000 units with the world's first self swapping battery, and EngineAI's natural gait machines walk police patrols. The category spans bipedal, wheeled, upper body and lifelike bionic forms.

Quadruped Robots and Robot Dogs

Legs for the terrain wheels cannot cross. Quadruped robots run from the world famous Unitree Go2 through the industrial B2 and explorer class A2 to Deep Robotics' substation proven inspection platforms, patrolling perimeters, reading gauges in hazardous plants and performing in synchronized troupes on the world's biggest stages, across standard and wheeled configurations.

Service and Commercial Robots

The robots the public meets. Commercial robots span Pudu Robotics' 80,000 plus deployed fleet, restaurant delivery and bussing, hotel couriers riding elevators, retail greeters advertising in motion, office mail runs, finance lobby reception, exhibition performers, security patrols and cleaning robots that document every square meter, with specialists from Keenon, Yunji and OrionStar deepening every niche.

Industrial and Warehouse Robots

The economy's muscle. Industrial robots from SIASUN's SCARA to tonne class arms and cobots share floors with the warehouse revolution: autonomous forklifts from Seer Robotics, lifting robots carrying whole racks, goods to person systems from market leader Geek+, transport AMRs like the PUDU T300 and the new warehouse humanoids working stations built for human hands, plus factory, welding, inspection and logistics specialists throughout.

Robotic Hands and Components

The dexterity layer. Robot hands from BrainCo's prosthetics proven Revo family and AgiBot's OmniHand with fingertip touch to the research standard Shadow Robot, alongside arms, batteries, sensors and the full accessories ecosystem that keeps fleets working.

Specialized and Emerging Categories

The frontier keeps widening: healthcare robots from hospital logistics to surgical systems, educational and research platforms training the field's future, agricultural robots and drones from XAG, government and emergency response machines, sports robots sparring on stage, UGVs for rough terrain and consumer robotics bringing it all home.

How Modern Robots Work

Learned Motion

The control revolution came from learning: locomotion and manipulation policies trained across millions of simulated trials, transferred to hardware, producing the balance that survives shoves, the gaits that climb rubble and the grasps that handle eggs, capabilities scripted robotics chased for fifty years and reinforcement learning delivered in five.

Perception and Navigation

Robots see through fused LiDAR, depth and RGB cameras, ultrasonic and inertial sensing, building live maps and localizing to centimeters without rails, markers or beacons, the marker free autonomy that collapsed deployment from construction projects to delivery day, certified to standards like ISO 3691-4 for sharing space safely with people.

Embodied Intelligence

Foundation models became robot minds: vision language action systems translating instructions into movement, agents planning and self correcting in closed loop, demonstration teaching that converts a human showing into robot doing, and fleet learning through which every deployed unit improves all of them, with multilingual conversation making the public facing tiers genuinely interactive.

Endurance Engineering

The deployment generation solved uptime: hot swappable packs, autonomous charging, self exchanging batteries and fleet energy rotation sustaining true multi shift operation, backed by the manufacturing scale, thousand unit runs and vertical actuator integration, that made reliability a product feature rather than a lab hope.

Where Robots Work Today

Business and Hospitality

Across restaurants, hotels, retail and offices, robots cover the shifts hardest to staff while adding experiences customers photograph.

Industry and Logistics

From factory floors to warehouse grids, robots run the material world, welding, lifting, hauling and inspecting, with documented labour savings and throughput gains behind millions of installed units.

Public Service and Safety

Security patrols, government deployments from border crossings to police support, and emergency machines entering scenes ahead of responders take robots where risk lives.

Science, Education and Sport

Research labs and classrooms worldwide train the next generation on accessible platforms, while robot sport turns capability into spectacle audiences pack halls to watch.

Field and Home

Agricultural drones and field machines stretch farm labour across more hectares, and consumer robots, companions and entertainers, bring the revolution into daily life.
