Last Saturday we APE.Robotics participated in the Science Fair in Kruševac. We brought the robots with us and decided to show them to high-school students as well as some smaller folks 🙂 As you’ll see bellow, it looks like in about fifteen years, we’ll have lots of folks doing robotics 🙂
And yesterday, that is, a week after the Science Fair in Kruševac, we visited Ćurpija. Not many know, but over there, there’s a group of folks gathered around a project called Biblioteka++. We shared with them what we did this year with the competition, how we organized and tried to motivate them a bit. They themselves are programming Lego Mindstorm robots and are making very exciting things. Be sure to check out their website as you’ll find over there very interesting things regarding both robots and programming in general!
It’s been a while since we wrote you anything, sorry for that. All of us postponed much stuff for after the competition so at some point we didn’t have time for anything 🙂
For those of you who came to the competition you saw what happened, for the rest of you, here’s the outcome.
During the first and the fifth round, our big robot worked very good. The little guy unfortunately tipped over and fell in front of the stairs both times. But even so, they beat the other team both times 🙂
However, during the second through fourth round, something odd happened. At the beginning of the round, the big robot wouldn’t start at all. 😦 We tested everything in-between the rounds and everything worked perfectly for tens of times. We’re still not sure what happened, but we’ll definitely work to find out. All in all, because the robots earn points and not victories, and we got almost zero points during the three rounds, we wound up 7th place out of 13.
We’re not happy with the place on the board but once we find out what happened, we’ll be sure that we now have a robust and controllable wheel platform along with a good software, so next year we’ll have more time for mechanism development and testing 🙂
Once again, thanks everyone for their large support!
Dana 25.04.2015. napokon se odigrava dogadjaj oko koga se ceo naš rad okreće – 13. nacionalno Eurobot takmičenje! Zato vas pozivamo da pomenutog dana prošetate do bioskopske sale SPENS-a u Novom Sadu i prisustvujete okršaju robota iz cele Srbije!
Time is running out as the competition is only 25 days away. Last time, we’ve left you with only a teaser of the mechanism drawings and since then we’ve been working hard on integrating separate components together as well as designing some new stuff. Today we can finally show you a fruit of our work – in the video bellow, you can see our robot earning his first points! While the competition is approaching fast, we’ll be working on improving the current systems as well as integrating the rest of the mechanisms so our robot can handle other game elements as well! We’ll try to keep you posted with the progress so be sure to swing by now and then 🙂
Again, a large thanks to all of our friends for their great trust and support!
Designing mechanisms is by no means an easy tasks. It is because of this that we have highly skilled experts in our team ready for a challenge! Unfortunately, this time we’ll have to leave you with only a teaser but be sure to swing by soon to see these drawings turn to life! 🙂
Everything’s much easier when you have friends to support you! This time, 3d-caddit lent us a hand – though as you’ll see on the image, kind of literally! 🙂 3d-caddit was kind enough to donate us ABS filament for MakerBot. Because of that, we were able to print some components for our robots’ mechanisms. On the image on the right, you can see a robotic arm which will be used for some of the games in the competition.
Thanks 3d-caddit! Hopefully, this will help us ‘catch’ some points! 😉
No one should ever be alone, especially not robots – they don’t take it very well. That is why we decided to make another one so the two of them can hang out! We are very happy to present you with our newest teammate. He’s still shy as he’s only a few days old but even so, we managed to catch him on film. Be sure to stop by and check up on his progress as we have a very strong feeling he’ll grow into a mature robot in no time! 😉
We’re very excited to let you know that Milestone 1 is finally done!
In the video bellow you can see our little guy following a square trajectory and returning to its starting pose. This demonstrates complete software and hardware pipeline functionality as well as the precision of odometric system.
As we finally have a solid ground we can start building up. In the following period be sure to stop by and check on our status with mechanisms development!
Once again, to all of you who support us and dedicate your time and resources a large thank you! This wouldn’t be possible without your help.
Just like people, robots have brains too. What differs our brains from theirs is that ours are composed of networks of neurons while robots’ are usually made of networks of transistors. Some robots have BeagleBone Black development platform acting as their brain, and now, thanks to 012LAB, our robots also have it!
012LAB was kind enough to donate us a BeagleBone Black development platform. It’s a board featuring Cortex-A8 microprocessor and can be useful for all sorts of things. We use it as a high-level controller utilizing AI and Game Theory algorithms to instruct other, low-level controllers to turn motors and similar stuff.
012LAB is a team of experts and electronics geeks who strive to popularize this interesting science. They are a part of 011LAB company which designs and develops innovative electronics products and high-tech systems. They’re also a certified SparkFun Electronics distributor so be sure to check them out for some interesting DIY and open-source hardware products!
One step at a time we are getting closer and closer to our first milestone!
Help is coming from all around, people are being extremely kind and generous. With their help, encoder mounts are completed and our robot is almost ready for it’s first steps 🙂
Lagerton provided us with some high quality bearings while 3D-caddit was kind enough to donate us with the material for MakerBot printer. Politehnika (a school where two of our teammates currently go to and where another one used to go) allowed us to use their machines for mechanical production as well as the necessary material. All of them were very quick to respond and pleasant to communicate with, so on this occasion we’d like to thank them a lot for everything!
It’s a bit hard to share our progress with the software, so we’ll just share the photos of the encoder mounts we made, and hopefully in several days you’ll be able to check back for a video of our first run.
