I am doing a project which will have an RC car drive autonomously using MPC. For this I need an indoor 2d tracking system. The RC car will be fitted with an IMU and I am looking to use a beacon system and combine these two using an extended kalman filter. However the beacon system has an update rate of 40 hz with a latency of 20-25 ms. How will this impact the correction part in the kalman filter, seeing as the correction data will be 20-25 ms old when it arrives?
Perhaps this was the wrong sub-forum, admin can feel free to move the thread where they see fit

I read through the "How to Build a Robot Tutorial", but I already have an Arduino Uno with a kit. I have some servos and sensors too. I was wondering if there is a beginner tutorial for those that have an Arduino already. Perhaps I have everything that I need, without spending more money?
I did a quick search, but there are a lot of results to filter through. I didn't notice a sticky.
Thank you for your time.

The server on the hosts' end occasionally had hiccups, and the MySQL db was in the middle of a write when that happened. It's like a one in a billion chance, but after 12 years it was bound to happen.
I just moved to a new server a few days ago, with an updated OS and everything.
SSL is a bit pointless as we don't really have a need here for encrypted security. No one posts anything personal or political and all purchases are done through Paypal....
I looked over Let's Encrypt, just added it to my list of things to do.

Obligatory relivant xkcd:
I'm glad to see SoR is still alive and kicking, despite lots of old timers seeming to disappear.
I do recomend that you set up an SSL Cert, you'll get higher ranking in Google, and Chrome and Firefox won't complain about unsecured connections. Take a look at something like Let's Encrypt

Thought everyone might be interested in the 2nd Annual Robot Art Competition (robotart.org), which features $100,000 in cash prizes. We're a nonprofit, and the contest is free to enter and open to any age. The goal is to challenge participants to produce something visually beautiful with robotics. It's ideal for robotic student projects involved in robotic planning and image processing, especially those who have an appreciation for art. Details, team signup, and last year's winners are at robotart.org.
Participants can use any robotic system to produce the artwork. While most teams are using existing robotic arms, the contest is open to custom hardware. Students can enter up to six paintings in each of the competition categories of "fully automated execution" and "manually (semi or tele-robotic) generated" art, where generally, there is little or no specialized software used to control the robot.
The deadline for artwork submission is April 15th. Let us know if you have any questions.
Thanks for your time,
I would like to share a video about our recent research on soft modular robots !
This machine is able to self-reconfigure into different shapes, similarly as living cells,...
ha,.. if you are interested in more info here is the link to the paper:https://www.researchgate.net/publication/312121627_Soft_Modular_Robotic_Cubes_Toward_Replicating_Morphogenetic_Movements_of_the_Embryo

Hey guys and. Gals! I haven't been on here in forever. Had some family health issues, so life took a back seat. Things have finally settled down though, and just when I decided it was time to start up playing with my toys as my wife puts it, I run across this at a scrap yard! A power chair! Paid scrap price for it too. 28.31. it's a good start! Now to take it apart to get it out of my truck. Lol

We are going to upgrade the entire server, the hardware, and the software, tonight. This will give us 3x the capability with half the operating costs.
Hopefully the entire process will be smooth and disruption minimal.
If at any time something seems odd, feel free to contact us. If you post anything, keep a backup of it for the next 24 or so hours just in case of the worst.
