Hmmmm looks very interesting is this going to be like a rover? Or a geological science robot ? Cool design.

Um, it's a toolbox

@spyder

A robotic tool box? Or just a tool box

I work at a video game arcade about half the size of a football field, and the goal is to have it follow me around so that I don't have to push a toolbox like the other techs do

@robo-pi

Yea, umm, exactly

?

The latest work on the toolcart1

I'm not entirely displeased with it so far

It's almost ready for the motors, but, I haven't got the computer bits sorted out yet ? 

After hefting this thing around, I've decided that it's just gonna be way too heavy for the axles I've got currently installed, so I ordered some beefy ones (and a few other replacement wheel things)

Which means that after I remove these I'm going to have some spare wheel parts, and I know just where I want to put them

They're going into the tank

The tank was supposed to be nothing more than an experimental test bed for ROS

But it keeps growing

While waiting for the Jetson to come back from the Nvidia Doctor's office, I'm busy making the head for the toolbox (yes, it looks like K-9. That was my plan all along)

It's 16 inches, so I had to break it up into sections to print it. Obviously I haven't connected the pieces yet. I'm making it out of translucent white to match the rest of the body cuz I wanna put lights inside it so it glows. And I left a big hole where the eyes go cuz I'm gonna print them in the new spool of translucent red that just came in the mail today. And with the touch sensors on the Adafruit Crikit Pi HAT I've got, I'm hoping that when you pet it, parts of it will light up

Although, now that I think about it, I'm not sure how good of an idea it is to give customers an incentive to touch it

Oh well, I'm not at that point yet. I've still got time to ponder the ramifications of incentivizing total strangers to lay hands on a tool that I have yet to understand how the programming will respond to said touching

Good thing I didn't design any teeth into it

@robo-pi

ill take 3 and one of whatever she was advertising 

I finished printing and hot gluing (and burning the **** out of myself) together the last of the K-9 head pieces, and was about to start printing the eye module from the spool of translucent red I thought I had ordered, but when I opened the box, it wasn't red filament I was looking at. It was a kind of whitish kind of color, so I looked at the box, and it said "glow in the dark red"

First I was ticked off at myself for ordering the wrong thing, but then my curiosity got the better of me, and I thought "I've never heard of RED glow in the dark. I thought it was always a greenish color"

So I grabbed a light, aimed it at the spool, and then turned off all the lights, and wow, it glowed RED

I still can't use it right now, but it's a cool thing to have, so I put it on the shelf and went about ordering a spool of translucent red (after, of course, carefully reading the description)

So, bummer that I ordered the wrong stuff...

And, cool, I got something new that I didn't know existed that I have no idea what I'm going to do with, but will be happy to make some space on my shelf of filaments for some project that has yet to identify itself

Okay, The head has been glued together. I printed the eye module. Now it needs lights, camera, sensors... maybe a laser

The nose and mouth are still open, so I can stuff things in there

And I can still modify and reprint the eye module. I haven't glued that in yet. I have an idea for an Adafruit Crickit HAT for a Pi

https://learn.adafruit.com/assets/62099   (a very cool thing I think)

that has 4 touch sensors on it. I was thinking that it would be cool if, when you pet the bot, some lights would flash in sequence, but I haven't completely figured out the Crickit HAT programming yet. Also, the string lights are an issue. The advert said that they were "individually addressable", but I haven't exactly been able to do that yet

What it looks like is that you CAN address them (sort of), but you have to reload the entire sequence of lights, not just one at a time, so I must be doing something wrong, cuz that sounds terribly complicated

The whole thing looks like a stack of pancakes, with the Pi on the bottom, and a 4 motor controller on top of that, and the Crickit on top of that. I've tested it, and I can control everything so far while they're all stacked together

Well, not everything. I haven't tested the speaker yet, but, that's not really a concern at this point as I have no idea what types of noise I want it to make yet, and even if I do, I think I'm gonna wanna use SNIPS to make it talk, which would be a different Pi altogether. But, again, I'm not there yet, although, I do have a PI with SNIPS loaded on it, along with a sound card. Haven't had much time to play with it lately tho

Getting closer

Testing out functionality of motor control and lidar... looks good so far

ROS is working as far as RVIZ

Still needs a brain

Spider,

You Inspire me! Man that is really cool, I like the PI and the Nano! K9 Toolbot looks great! Sonar and lidar wow it can see and hear better than me (lol) and a camera to boot! Awesome! I just have a couple of questions... What did build him out of? What did you use for motors? He moves so quietly! You said he takes a lot of batteries Can I ask what kind?

Like I said that's awesome!

Um by the way it was the Scarecrow that wanted a brain the lion wanted courage. I got what you meant though.

Thanks
