Benefit Of Onboard Computer
Hello to all the members of the community here.
I am starting to build an InMoov robot project using ezb controllers and want to understand what if any is the benefit of adding a onboard computer to the project is? Also what computer configuration would be best to use?
Currently I am going to be using a IoTiny in the head and two ezb4’s in the chest.
Related Hardware EZ-B v4
Now I need to decide how I want to power it. I was going to go with a 6V 50A switching power supply to power everything and use a BEC set 5.1v for the LattePaanda and powered USB Hub.
Does anyone have any comments or input on the power setup?
That will be a hefty power supply. Enough for the servos for sure. Be cautious of wiring to ensure the cables can carry the current.
I use a single ezb v4 via usb to the onboard computer. The ezb has an ssc32 connected for extended servos. That gives me 66 servos capability with one ezb.
I use a usb camera. For speech recognition I use a Jaba audio conference speaker/mic combo mounted on the front waist.
originally I had the camera in the eye. But since then I realized it makes more sense on the chest. People don’t know that it’s on the chest, but it allows the robot to track objects easier.
Can you tell me what USB Hub you picked to use and helper board for the USB EZB4?
As soon as I start my ARC Pro subscription I will start posting details about my build under the robot section of this sight.
I don't know what USB <-> uart I am using. Any that works with Windows 10 will suffice. The internals always seems to be the same.
I don't use a USB hub because I only have three devices connected: a USB camera, sound, and ezb.
I'm not sure what power supply the inmoov has - but Jeremie might chime in if he sees this post. He found it for me.
They are common, you should be able to google it, or you can use an ATX power supply if you have one. Obviously the 5V rail.
I also got to thinking after my last post that I don’t think I need the IOtiny in the head if I install the pc because I should be able to use 8 ports on the GPIO to run the servos. If that does not sound correct please let me know.
I have so much to learn and I really appreciate your guys help putting me on the correct path on this project.
Can you you make the latte panda boot without pressing the on/off button on the board?
I want to mount the board in the head of my inmoov but that is not going to work if I have to turn it on by pressing the button on the board.
Also can you make it auto load an ARC project when it starts up?
Thank you in advance.
You can have ARC startup with projects etc. Here's the support section link: https://synthiam.com/Support/Tips-to-Make-a-Robot/Load-project-on-Windows-startup
Also, be sure to follow the guide to install windows for performance, or you'll be kicking yourself later :): https://synthiam.com/Support/Tips-to-Make-a-Robot/Overview
How to switch on/off the Auto-boot function in LP v1.1/v1.2:
1.Press [Esc] or [Del] once just boot up the system to enter the BIOS
2.Go into Boot->Machine Status AC/Battery In
3.Change it to Power On/Power Off
So thank you for pointing me in the right direction! As far as all the performance settings I have also done them per your recommendations.
Leonardo, Micro, Yún. 3, 5, 6, 9, 10, 11, 13 490 Hz (pins 3 and 11: 980 Hz)
one way is to try a port and see if it works
ok well thanks for your validation DJ.
i know some things but I don’t know all things haha
I would love to be able to talk to you about ARC programming for a few mins on the phone to try and get a better understanding how thing are designed to work with each other. Let me know if that is something that maybe we can do.
