Turtlebot 3

Post by dbc » Thu Oct 13, 2016 6:44 pm

I note that the new Turtlebot 3 has an STM32F746 of some flavor:

Presumably this is to handle the hard real-time tasks of motor control, servos, etc, because the robot is targeted at running ROS, which requires Linux and an MMU. ROS does run on a RasPi, however, so I expect most people playing with the Turtlebot 3 will use a RasPi, at least to start. The board and microcontroller firmware are supposed to be open source, so maybe we have another interesting platform for a MicroPython port?

I'm not sure how to get hold of one of these units yet, but when the OSRF people get back from the conference in Korea I'll quiz them a little more.

I read on HBRobotics mailing list that it will be available in early 2017:

TurtleBot3 was also announced on the ROS mailing list: http://discourse.ros.org/t/announcing-turtlebot3/623

This page: http://spectrum.ieee.org/automaton/robo ... nd-modular
has a picture of the controller board which includes the STM32F746

Yeah, Camp is quoting press releases. The photo link is the same one I posted. If Tully shows up to board game night tonight I'll ask him about it, but I suspect he stayed on in Korea for IROS after ROSCON ended.

What isn't clear from the picture is which model of STM32F746 is used on the board, the 1M or the 500K flash version.

The OpenCR board is the control board for Turtlebot3 and main mcu is stm32f746zgt6.
It doesn't have SD Card interface on the board. It is important to use MycroPython on the board?

There are source codes and hardware files on github ( https://github.com/ROBOTIS-GIT/OpenCR/ ) but it is not the lastest files yet.
