  Inexpensive Cat-Following Robots (Require Extra Equipment) Budget camera cars from about $30 to $100. Most stream video over Wi-Fi to a laptop that runs the cat detector, and two have an AI camera that spots a cat by itself. They follow a cat in view but cannot map the house. 7 robots · Keyestudio KS5017, Freenove (ESP32), Maqueen Plus V3 + HuskyLens, ACEBOTT QD001 + QD002, ELEGOO V4.0, PiCar-X and Roboduino V2

  Cat Following Robots (Onboard CPU) Robots under $1,000 that run the detector on their own computer, with no laptop needed while running. Most carry a lidar for mapping and ROS 2 navigation, so they can search other rooms for the cat. 7 robots · Bittle X, MentorPi M1, ROSMASTER M1, XGO-Rider2, UGV Rover, Mini Pupper 2 and PuppyPi Pro

  Cat Following Robots (Onboard CPU / Depth Camera) Rovers from $459 to $995 that add a depth camera to the on-board computer and lidar. The depth camera spots low clutter such as a book or sock on the floor that a lidar misses, so navigation can steer around it, and it measures the distance to the cat. 7 robots · RDK X3 Robot Car, ROSOrin, ROSMASTER M1, UGV Rover, ROSMASTER M3, ROSMASTER R2 and MARS
