GR-ROSE is a small board for prototyping robot and IoT system. Enable simplified distributed processing for robot operation with open-source software like ROS2, Arduino and AWS FreeRTOS. The physical interfaces to attach serial servos, to supply voltage and to connect sensors make it easier to incorporate into robots. In addition, AWS FreeRTOS enables multi-task programming and easy connection to AWS IoT.

How to Program

Sketch Reference


3D Data for Fusion 360

3D data that can be imported with Autodesk Fusion 360. Use it when making cases for GR-ROSE.

 

 

Fritzing Data

Data that can be imported by Fritzing. Wiring of a solder-less board can be done easily. (Designed by ksekimoto)


MicroPython

GR-ROSE can run MicroPython. (Published in GitHub by ksekimoto)

In order to run MicroPython, copy the bin file below to GR-ROSE after pushing the reset button.

Board Definition File for e2 studio (BDF)

This file can be used with e2 studio. It is useful when developing new GR-ROSE software.

GR-ROSE-v1.00.bdf (5KB)


Factory USB Firmware

At shipment, USB firmware is written into the microcomputer. When you press the reset button, it becomes storage, and copying the bin file executes as user application.

USB Firmware

After setting SW1 of GR-ROSE to "P" and connecting USB, you can write the MOT file with Renesas Flash Programmer (RFP).

The project file for e2 studio is below. CCRX is required to compile. Refer to the e2 studio product site for download and installation of e2 studio.

You can import as archive file (zip) as existing workspace from e2studio menu "File" -> "Import".

Note: This is a project exported in e2 studio version 7.2.
