And finally its setup... Working well with four.. hopefully would convert it to 1x4 instead of 2x2....

The fact you’re older doesn’t give you the right to call other people’s 8-months’ engineering effort “shit work”, especially if you didn’t even see the code...
Sincerely,
Your tech lead - me :)4 -
That time I joined the robotics club and made the pid loop for the robot was one of my favorite projects. I learned ROS, and I created the entire chain of software and hardware to control six motors. That one project set up my experience for the next 4 years and led to a few jobs. I miss robotics.

Did you know?
Ubuntu 16.04 can't build ROS.
Fsck!
I look retarded running a VM of Ubuntu 14 in Ubuntu 165 -
There are legal companies in my home country who make a living by selling pirated games and software for only 2$ each...

That moment when you change your mindset from "I'll probably leave the office by 6pm" to "I hope I'll leave before midnight"1

While working on my localization algorithm, I also set up a baseline I can compare my results to. I chose AMCL which is the go-to localization package everyone uses in ROS.
I took a peek at their code and found this atrocity - "ad hoc weighting scheme" where probabilities that are not mutually exclusive are added together, and also taken to the power of 3 because why the hell not!
6 -
My anxiety levels skyrocket when my hypothesis is actually verified in experiments. It gives me that haunting feeling of "I must have done something wrong at some point."3
-
So I integrated the second Lidar, and did a small quantitative evaluation - the localization succeeded in 133 out of 135 scenarios.
The next step is to tentatively port all my python code to C++. So I started this today, and while I always hate on Python and say I like C++, porting all this code looks so damn painful....10 -
My day:
5:30AM - 2yo son wakes me up, I send him back to his bed
6AM - wakes me up again, gotta grab a coffee
7:30AM - leaving towards the office
8:30AM - finally arriving to the office, after horrible traffic.
*continue working on major schema change I started yesterday*
12:30PM - Lunch + Beer
1:30PM - Tequila time!
*back to work*
7:30PM - Finally done with coding, leaving the office
8PM - home at last
9:30PM - Beer time
9:31PM - "I'll just write a couple of more lines"
12:30AM - "That's it, no more code for today"
12:31AM - "I'll just scroll through devRant"1 -
So I made an ancient robot work with ROS2, and revived the motion capture system so I can collect (and sync) Lidar scans, odometry and GT pose. But the worse is ahead of me...

left the office early today to see my 2 years old son before he goes to bed.
it's 11pm and I'm working from home, gonna wake up around 5:30am to commute to work.
I really need to move closer to work3 -
First results from my work on the YouBot - Localization based on lidar and wheel encoders. My algo is still over-confident, and I need to improve it. But just getting all this shit to work together in ROS was so hard...
For now it's in Python, but when I am sure of its correctness I re-write it in C++ and ROS2-compatible

ROS is on top of that list. It's a disappointment that has turned into an industry standard.
If ROS can make it, you can make it too!12 -
I can't share details of ongoing research projects (NDA-esque) which is frustrating because I do want to rant about them.
Let's it just be said I'm frustrated with ROS and packaged built on top of it about five times a week.7 -
on one hand- got a new job, on the other hand getting a new MacBook pro just before they release a new generation2
-
So I've been working on collaborative localization, which means robots in a team help each other improve their pose estimation!
We submitted a paper to a robotics conference (fingers crossed), and you can find a video from the demo here:

I might be pushing my 4 years old macbook pro too hard with 2 IDEs, 1 instance of datagrip, and tons of open browser tabs, all on 4gb of RAM..6
-
what the fk how hard can it be to have a working version of the software on the master/ ros-version branch? Why is this thing always broken?! HOW?!
Had to update today unfortunately, and man, I have been "installing" this shit for over 3 hours now. Use the .install they said. It will be fast they said. Ye sure, my ass. The Dependencies are broken and incomplete as always and the tutorial is not up to date. Big suprise. I get it, it's a lot of work to keep these things up to date. But please if they are this broken and incomplete why are they released in the first place.
And then they wonder why I don't manage to do my work on time. Yeah, cause I'm stuck debugging this shit <.<'1 -
Multi-rant incoming!
1.
Stereotyping.
When did that shit become the norm?
2.
I'm lost in ROS smach. Does anyone do multi-threading in ROS services, or should I flip a table on smach? 😒11 -
Teammate turned my neat minimal service architecture into dog's breakfast.
Now I don't know which one I hate more. Him or ROS.4 -
I love robots and I so-fucking-much love working with them... But for some reason, which may very well be exhaustion, I am not looking forward to tomorrow and writing ROS services for the currently packaged stuff.
*sigh*1 -
Brewmaster.
I've been brewing my own beer for about 6 months now and super positive feedback keeps on coming :)2 -
developer oriented saas? well yeah, you could've at least develop a decent SDK for one language, or just let people send JSON payloads instead of XMLs..a**holes

Python file truncate instead of actually deleting file contents...
there goes a weekend of log backups.. FML -
Soo I've written some python code to test things for my soon starting bachelor thesis. I work with a little robot car I share with other people and use 2 cameras on it. Today I make the extra effort to go to the lab to test my things as there were too many people busy with the available cars yesterday.
Set it all up with ROS and my project as per usual just to see whether python fucks me over again ... nothing, ok what a surprise.
Good part: my python code seems to work flawlessly
Bad part: cameras don't work, although they don't throw any errors. Quick check with rqt_image_view ... everything seems fucked up, but not broken. Cameras not accessible as they should be, only 1 view available instead of the normal million modes and a blank grey camera stream on the screen. But no errors, nothing.🙄😪
I also wanted to capture some footage to test at home, well that's gone to shit. Now I had to simulate that using my phone camera ... while crouching.
Fuck ... me.1 -
Goal for 2019
- finish project I started in Q4 2018 and launch website with it
- maybe find some non invasive way to monetize this and earn some money
If I got time and power left :
- learn more autodesk fusion,
- design robotic arm using above tool
- print it in 3d
- program it with ROS arduino/rpi
- put it on some wheels
- make it driving around my flat
- make it pick up stuff for me -
Going over some NodeJS code, and I feel like the scene from "Dude Where's My Car" - "And then....And then..."
Coming from almost three years of 99% python, this hurts my eyes so much1 -
So I developed this proxy server that will throttle down API calls to one of our providers so we don't get blocked for TOS violation...
Some dude had a tool running all day long which crashed 2 minutes before I left work.
This literally ruined my day until I recalled it's all cached!!!!
Mood is back again and I deserve my beer! -
Just spent a lot of time on custom building an Ubuntu docker container, and forgot to save the image before I accidentally reset the whole thing to blank1

So I've been on vacation for a week now, still two days to go until I get back to work.
It's been super fun, but I am getting pretty stressed about the shit-ton of work I have to do when I come back.
How do you let go?2 -
Make your code available for your team members, please.
So we're working on this robotics project using ROS, a framework that enables multiple nodes in a network exchange their functionality among each other through tcp connections. Each node can be implemented and executed on your own machine, and tested with dummy inputs, but in collaboration they make a robot do fancy stuff.
The knowledgebase needs data from the image processing unit, providing this data to others with semantic context to high level planning, which uses this semantic data for decision making and calling the robot manipulation node with meaningful input, to navigate the robot's components in the environment. We use a dedicated machine, which pulls the corresponding repositories and is always kept configured correctly, to run each node, such that everybody has access to each other's work when needed.
So far so good. We tried to convince the manipulation guy (let's call him John) to run his code on our central machine, not a week, but since the first day, 5 months ago. Our cluster classification has been unavailable for 2 months, but my collegue fixed that. We still can't run the whole project without John's computer. If his machine blows up we're fucked.
Each milestone feels like a big-bang-test, fixing issues in interfaces last-minute. We see the whole demo just moments before our supervisors arrive at the door.
I just hope he doesn't get hit by a truck.2 -
Playing around with a POC I'm doing for work, and it works so well I got an IP ban from one of my favorite websites for a massive amount of requests they got from me

Getting started with Python's asyncio is probably the worst experience I've had with the language in 2+ years I've been using it.2

Any terminator experts here?
I want to make a setup of multiple split windows starting things on launch. I got so far that I get all the windows with the layout option but I cannot launch what I want via custom commands.
I want to launch multiple ros launch files like that.
Any ideas?8 -
Trying to build a ros workspace inside VMware...
Called up the teammate who put it together:
Me: hey the workspace isn't building for me, do I need to setup anything before I type "make"?
Him: nah dude just type make and ur good, why what error are you getting?
Me: *describes error*
Him: oh lol I never got that error before, idk maybe your machine is just dumb
Me: *uh ok sure dude* let me try some other stuff
*Boots to native install of Ubuntu*
*Build successful*
Me: oh huh that's weird it built on my native installation but not on the VM
Him: oh lol that's not my problem
Seriously dude? First off, screw you Ros for not being able to build in a VM. Secondly, it's entirely your problem! Linux is nice to use, sure, but it's a bit of a problem when the entire team runs off Mac!
😲😲😲😣😥😫😓 -
All I want to do is build a robot. ROS is slow as crap on a raspi when you're trying to do SLAM. The chassis isn't big enough for a second raspi, and I can't print a bigger electronics tray until the end of my week off.
Also, Ubuntu just doesn't want to work right on my Surface. Emulation too slow.
So much for building cool things on vacation. -
Wasted 5 hours to implement video recording with cv2 in python. Followed the tutorials and searched SO for help. The video file I need to produce just doesn't get produced. It's a camera stream from ROS. Yet no errors that might help. Or even any errors. Thanks.
It's for my bachelor thesis. Fuck.4 -
Installing the entire system on new machines. Too many configuration files and too much manual work. (New workplace, haven’t automated it yet)
-
Writing DAL code that I am 99% sure will be replaced really soon along with the database schema.
Angry coding is almost as good as tipsy coding - AMAZING. -
Finance lady keeps turning the air conditioning off.
It's either sticky note on the controller or R&D vs. finance lady on an on/off battle...
What do you say? -
So I just refreshed LinkedIn and it has a new look.
It's so bad I can now remember Microsoft bought LinkedIn a couple of months back every time I look at it1 -
Ex-manager keeps trying to boss me around. Not only that- he now tries to get fame for a project I’ve been doing for six months that he actively avoided managing...

on one hand - softlayer is way less intuitive than aws...
on the other hand - when your boss tells you you can bring up up to $1000 monthly valued servers, you can forget about the first hand

No rants about new MacBook pro generation? Obviously one must rant about the absolute need to buy adapters to connect keyboard&mouse (let's be honest, BT devices out there are mostly nowhere near ergonomic)1

Camembert cheese in the fridge is great, but how can one survive without the stronger Nespresso capsules ;(

Read about concepts that are new to me and try to implement them.
Code reviews with experienced devs -
Ros melodic in a strictly python 2.7 environment mixes horribly with a PyTorch based RL module... Time to work around with terminal calls from the latter
*sigh*1 -
*builds workspace*
rosjava: error
.....
*build workspace 5 min later*
successfully build
?! Why is rosjava like this I didn't change anything!!! wtf can it please stop <.< -
So I spent about a day on this brilliant priority calculation formula just to come to the conclusion that FIFO would be a better approach for now1
-
POCing a neural network thing.
Luckily it's a shallow network, but it's taking a frickin' eternity to train :( -
so they brought a senior engineer to our (very small) dev team. I feel like poking my eyes with a nail looking on his code.1
