I am working on a Humanoid style Robot as seen here. I ran into a dead stop yesterday as the Arbotix Pro Robocontroller appears to have up and died on me (R.I.P. Arbotix Pro: 2016 - 2019). I contacted Trossen Robotics to see what my options are due to its age (1.5 - 2 years old, don’t remember exact purchase date), while waiting for a reply I was planning on purchasing another Arbotix Pro. I found that the Arbotix Pro is no longer listed for sale on their website. I searched high and low and can’t find any for sale online, not even on the manufacturer website. They only list the Arbotix-M for sale which brings you to Trossen Robotics.
So here’s the issue. I have a Arbotix-M already, but I don’t know how to get it connected up with the Raspberry Pi 3B or 3B+. The next concern is, if I can get it connected, will it run the code that I already have in place with maybe a driver tweak. This needs to control 20 DYNAMIXEL AX-12A Actuators and eventually a camera for head/color tracking that will be added in the future (possibly other sensors later). I searched the web and have been unsuccessful at finding the guidance I am looking for.
Is there a better way? The software code is a direct copy of the HR-OS1 from here.. This is for a Raspberry Pi 2. I fully updated the image using:
sudo apt-get update && suds apt-get upgrade
After that, I used git to clone the repository to the RaspBerry Pi 3B, then installed all required libraries and compiled node.js (took nearly 3 hours on the RaspBerry Pi).
Since I have an HR-OS1, I swapped the Micro SD card with the one I am building to confirm it all works, and as suspected it worked. Trossen hasn’t released an updated image since 2016, their latest image doesn’t work with the RaspBerry Pi 3B out of the box.
Any ways, I now have no immediate way to solve this and am looking for ideas. My knowledge here is still limited but growing. Looking for a method to get this robot running.
- How do I successfully connect the RPi3 to the Arbotix-M?
- Anyone have a link to purchase another Arbotix-Pro?
- Anyone have a working Arbotics Pro they want to sell for a reasonable price?
- Is there another method to accomplish this task? (I know there is but what actually works)
Any help would be appreciated.
