I do a lot of hand-building too.  Mainly because I can't afford to buy manufactured parts. 🤣 

I don't have a 3D printer myself, and it's highly unlikely that I'll ever get one, simply because of the cost factor.  Not just for the printer, but for all the accessories and plastic reels etc.

Not only that, but a lot of things I see people 3D printing I could make just as easily in my woodshop or metal shop.  There's also two ways to build with metal.  I can work with bulk metal using a lathe and milling machine.   Or I can work with sheet-metal forming and make a lot of stuff from sheet metal too.

I've also been saving up aluminum cans.   I have a ton of them and I would love to get into some aluminum casting.   Especially with the lathe and milling machine where i could then just clean up a casting and do fine machining on them.

But yeah, a hand-built robot can be quite satisfying.  Thanks for sharing the video of Duce Robot. 👍 

It's obvious that you've put a lot of work into Duce.

Awesome job on the robot. Looks like a lot of hours have gone into it.

thanks! hand build certainly can be fun even if it doesn't come out just perfect and that is a good idea with the cans for casting .you could cast a strong one piece base.

Who thinks the Jetson is weak? Not for processing power but for pin outs all the power to run a big project but one i2c connection ? Boils down all this time invested ...........can't use it every module is running something except that it isn't even running any LEDs sure it has lidar ros and move it but no real way to implement it simply just not enough hook up on it for something big not nearly ! For the jetbot I'm sure its great but nothing bigger than that ! Also who thinks ai and the waist of time on it should be for a robot only seriously!? Who wants to invest time on a desktop ai project when you can be devoting that learning time to actually be using it on a robot? Isn't that what ai  is primarily used in ? Just saying I would want a robot with ai not a desk top device..👍

It is not a case of one or the other. Most useful AI can be found on a desktop or a mobile phone.

A machine doesn't have to "move around", that is, have a body in order to perform a task which if performed by a human would be considered to require "intelligence" (AI). Tasks that some current AIs are good at don't require a body. Siri for example. AI that plays chess. AI that looks for cancer in xray images. AI that identifies a plant in an image taken by your mobile phone's camera.  Accounting tasks and so on ...

Some tasks do require a body to carry them out. That is where the robot comes into play. There are simple tasks that a robot may carry out that don't even need to have much AI beyond the ability to carry out simple physical tasks with great precision and speed.

Back in ye old days I thought of robotics as being about the hardware while AI was mainly about the control system (cybernetics, steersman). This can be as simple as controlling the air conditioning in a house to something more complex like driving a car.

@robotbuilder this is true  I'm just experiencing builder frustration lol when you're on the brink but not just there yet you're grinding away on the last 38% of things that need to be done but none of it seems to be moving anywhere. I think that's where I'm at now lol👍😁

@duce-robot

And what is your end goal with this project?

There are many ways to expand the I/O capability of the Jetson Nano GPIO pins.   Same is true for a Raspberry Pi or any other SBC that has GPIO pins. I can't see that being a major problem.

If you are developing your own ai software it shouldn't matter whether or not you actually have a physical robot on hand.  Everything you learn about it will be easily transferable to a physical robot anytime you're ready to do so.

On the other hand, if you are using ai software that has already been developed by others for use in a robot, then there probably won't be much you can do with that until you install it in an actual robot.

I think it all depends on what you are trying to do.

I'm currently working on what I'm calling a Linguistic AI project.  It's all about creating a computer mind that can learn and converse using English as the language.  I certainly don't need a robot for that.  However, if I manage to create this AI mind it could certainly find a use within a robot. 😊 

In short, it could become the mind of a robot.

@robo-pi yes it certainly get tedious building a real robot but I'll put the brain in duce sounds awesome I plan on putting espeak in it if you know how to increase the pin out potential I'm all ears I don't have a clue but it seems like they should all be i2c connections parcelled out for every part of a robot drive speech arm camera in a perfect world lol .but my end goal is fun and wonderment ! Selling fun what a concept I'm certainly open for suggestions . thanks 👍😀

I'm not sure exactly what you want to do, but Bill had a video out a while back on a really nice I2C module that allows you to interface with multiple I2C lines.
