A IMU helps to make localization much more stable by providing accelerometer, gyroscope and some even magnetometer data. cartographer can easily be setup with IMU to improve localization.

• MPU6050 - IMU sensor combining a MEMS accelerometer and a MEMS gyro on a single chip.

A LIDAR (Light Detection and Ranging) can create an accurate representation of its surroundings by utilizing a laser and a light sensor to measure TOF (Time of Flight). Devices are available as 2D and 3D variants, although the 3D variants are still pretty expensive and do not add much value to the "robot vacuum" use case.

• camsense-X1 - Unofficial reverse engineering of a Chinese LiDAR. GPL-3.0
• RPLIDAR A Series - 360 Degree Laser Scanner with ROS integration and up to 16K samples per second.
