Epson Sensing System Sensors

Contents

The ROS drivers are intended for evaluation of the Epson IMUs on a ROS1 (or ROS2) system.
There are different Epson 6DOF IMU models with various sensing ranges that can be evaluated in a ROS based system.
These are performance-oriented products with a combination of low power consumption and small size.
G3xx models are intended for board-level integration using a SPI or UART interface
G552PR models are intended for remote cabled mounting in harsh environments exposed to moisture or dust connected using an RS422 UART interface
For more detailed product info & specifications please refer to Epson Sensing System

* These ROS drivers are available for download from

The ROS drivers have been tested on the following host platforms:
- Intel PCs running Ubuntu 16.x Xenial, Ubuntu 18.x Bionic, Ubuntu 20.x Focal
- Raspberry Pi 2 or 3+ running Ubuntu Mate 16.x, 18.x, 20.x
The latest ROS1 & ROS2 drivers have been tested using:

  ROS1:        Melodic & Noetic
  Description: Ubuntu 18.0x & 20.0x LTS

  ROS2:        Dashing & Eloquent & Foxy
  Description: Ubuntu 18.0x & 20.0x LTS

There are two separate driver packages for each type of serial interface connection to the Epson device
Use the correct ROS driver package based on the serial connection type: SPI or UART
For G552PR choose the UART version of the driver
- The ROS system must have a RS422 I/O compatible UART interface (UART protocol over RS422 Physical Layer) for connecting to the G552PR IMU
