Rebuilding Stabby Pt.2

I stripped Stabby down to the barest of the motor frame… I didn’t think I’d have to go this far down, but, the difference between the two track types is significant!

The new tracks are at the top, the old tracks are at the bottom. The new ones are 5 studs wide, 2 studs wider than the original ones… sooo… yeah, total redesign of the chassis to accommodate them.

Lookit all of the pieces I had to tear off poor stabby! :(

Wait a minute… is that a functional powertrain? … … … Why YES IT IS! A total redesign, but, it gave me opportunities to make improvements to the original design!

For example, I was able to better fit the rear access cover, it sits solidly now and doesn’t feel like it’s just bodged on.

Under the access panel, the battery box… looking at this picture, makes me think I need to flip it around… hmmmmmm. (It is about midnight here right now… sooo…)

And finally, a front view, the new servo motor is visible with a long axle coming out of it. I’m waiting for the third IR sensor to arrive so I can hook it up to its own channel for the speed controller on the remote. Stabby’s head stalk will have full 90° movement left and right, and, will also be able to incline his head. I haven’t worked out that feature yet, but, it will happen!

Yeah… I know! he looks so cold all naked down to his bare chassis! But, I left the design similar enough, the side panels I already have made SHOULD snap right back on.

Alright, those are the updates for today, I’ll post a video tomorrow of his movement! Whatcha all think?


Robot Guides Soybean Plant To Light

by Karin Heineman, Inside Science

What happens when you combine a soybean plant with a robot?

You get a soybot!

Developed by researchers at Purdue University in West Lafayette, Indiana, they’re on-the-go micro gardens that help indoor plants seek out light.

“They’re equipped with two sensors that measure light conditions, they move continually in the direction of the brighter light,” said Shannon McMullen, a sociologist at Purdue. Learn more and see a video below.

Upgrading Stabby...

Stabby says HI! but, he is totally going through some upgrades right now, so, he’s… in pieces… !

Disassembled Even! Poor Stabby!

But, UPGRADES! Seriously, the first main thing is a change of shoes… uhm, tracks…

On the right are the original tracks, small, dinky… serviceable, but, well, dinky and would get thrown if the little guy came across an obstacle. Also, He could not pursue anyone onto tile floors, no traction! So his main objective, slicing ankles, could not be achieved if someone retreated to my kitchen or bathroom… On the Left, are the upgrades, and, they come with rubber inserts so… there is no safety on the tile!

The next upgrade is the neck motor!

I got a Servo Motor (bottom) to replace the M motor (Top) for his neck! The M Motor is a full rotational motor, so, I had to use a clutch gear and stops so he wouldn’t spin his whole head stalk around and break the wires that light up his eyes. The Servo Motor is limited to three main positions, Center, and 90° Left/Right, if used with a toggle switch, or, if you use a speed regulator, it has 7 increments between center and full left or right.

Which leads me up to the controller!

Lookit that beauty! I have a third IR Receiver coming in, so, three remotes, Red on the left controls the left tracks, blue on the far right controls the right track. That leaves blue on channel 2, and red on Channel 1 for accessories. The Speed controller in the center, is going to be set for channel 3, and will control the head motions, turning left/right, and elevating the head up and down!

So, stay tuned! I’ll post more updates as I get the sprockets in for the new treads, the new IR receiver, and start implementing the upgrades!


anonymous asked:

yesterday my dad called roombas "lazy robots" and my immediate response was to call from across the house, "roombas aren't lazy they work very hard!!!"



N4-R4 was just a simple robot that had the misfortune of getting caught up in the whole rebellion after being hacked by some rebels passing by. Despite wanting no part in the fight, he was fiercely loyal to his new owners, until they were all wiped out, that is. multiple fights left N4 battered and full of holes and exposed wiring. 

N4 enjoys making little flying drones in his free time, which he has plenty of considering the fact that all he does is travel around in the desert with another misfit western roomba robot. Now this robot is quite the feisty one, despite being neutral in the ongoing rebellion, he’s always prepared to fight. befriending this bot is difficult but once you do, you have a loyal friend on your side, no matter how aggressive he may be.

All I needed
was a vacuum

What I got was something
easier, he said

when I made arrangements to pick it up
from the parking lot of McDonald’s
Easy as a drug deal

I put it on the floor
and as it chortled and gurgled in MIDI
I resisted the urge to pet it

I almost named it Clara
for the companion girl-gone-Dalek
but I didn’t want to be weird about it

The robot zoomed its flat circle body
exploring my hardwood floors
like Neil Armstrong

I didn’t have the heart
to tell the robot I was here

When it docked successfully
it was so proud of itself that it sang
with the fervor of Beyoncé
at the opening baseball game

There were no fireworks
which made me a little sad
but I don’t need my outlets blown

The robot is infatuated with bathrooms
The robot forgets that it cannot reach the handle
to open the door after it closes it

The first time it bit down too hard
on the rug tassels, the robot wailed
distressed and dying

Did I verbally reassure the robot
while I pulled out the poison whorls
and unwound a long hair from its works
before I set it back down on the floor?

You bet I did


The robot ate an argyle sock
The robot knocked over the cat’s water dish
The robot is too tired to clean the kitchen
The robot needs a doctor
I mean repairs

I’m sorry,
I can’t right now
I’m doing maintenance
on the robot

As I take out bread bag tabs from its bristles
I think of the man in the McDonald’s
asking me if I intended to hack it

Instead, it has hacked me

The future is here
and it is me on my knees
yanking hairballs out of a domestic droid
while it softly boops at me

Roomba Art - Long Exposure Shots of Roombas in action

These photos are made using Roombas autonomous robot vacuum cleaners. By attaching differently colored LEDs on top of them and using long exposure photography artists were able to capture the cleaning paths taken by these robots. Some of these are also as a result of programming paths, the effects are these long light paintings.

These are part of a “Roomba Art” picture series produced by multiple artists on Roomba Art Flickr & IBRoomba
