I am working on a soccer robot for robocup competitions. I have found some interesting omni directional wheels for my robot which has some significant advantages. It is thinner and lighter than the most of the other omni wheels. Moreover it has a good friction and I could move my robot very easily and efficiently.
I want to suggest you to see these interesting omni wheel
the website is :www.gtfrobots.com
does anyone have use them already?

I would suggest checking out Webbotlib and WebbotlibStudio, but that's just what I use with AVR boards.
The USB cable is nothing special; just a USB Mini connector.
That said, these days I just use a 6pin ISP programmer and avrdude to write the .hex files to my boards, rather than using the bootloader (especially since the FBOOT.exe file is flaky on newer Windows OSes, iirc)

Along with the advance of the times and development of technology, our material life has been greatly improved, people have become more and more particular about toys. Therefore, traditional toys are unable to satisfy the current "little adults", the children need more challenging, playful toys. Intelligent robot, the new era of toys that can accompany children, interact with children, are gaining popularity. Through interaction with the children, it can develop their intelligence, and cultivate children's ability to think, analyze and solve problems independently, at the same time, parents can also be involved in children’s growth, narrow the distance between parents and children.
All parents want to give their children the best things, including toys. Like Cookid intelligent humanoid robot from Shenzhen Cookid Technology Co., Ltd. we firmly believe that high-quality toys are not only safer, but also have a unique positive aspects on early education. Especially in the era of intelligent robot, children are become more fascinated with entertaining robot. Because of the birth of the robot, there is a new change for the family communication, the childrens’ taste of science and technology. However, there is a problem of overpricing and homogenization in the market at present, in the intelligent robot blowout period, Cookid humanoid robot with functions of intelligent companion, entertaining and so on.
Cookid intelligent humanoid robot, belonging to Shenzhen Cookid Technology Co. Ltd. , is born in such fast changing environment. Cookid robot can complete a variety of complex actions, such as dancing, doing gymnastics, performing kung fu, it can also be controlled by PC, tablet, mobile phone, meanwhile, it also has functions of video surveillance, intelligent home, video call
The important function of intelligent robot is accompaniment , those parents who are busy with working have little time to accompany their children, with the development of science and technology, intelligent robots can be better used to accompany children. The intelligent robot can not only help busy parents, but also work as a warm playmate in childrens’ growth. Although the robot can not replace the love of parents, but in a certain extent, they can solve the problem of children’ loneness.

Good afternoon everyone,
I am using the MaxBotix MB7092 sonar
I've been doing my homework and have been stumped on trying to get underwater ranging finding to work. I've looked at the numerous threads
(& followed his video
on it) that Admin & others have made yet I'm still having trouble.
I know that temperature and salinity can affect the readings and I've been actively trying to compensate for that in the code by measuring temperature from a separate sensor and multiplying the analog reading from the sonar by 4 on average (Fresh water @ 20°C) and still no luck. I've also tried compensating for it from the Serial output of the sonar to no avail.
End goal is to get it measuring the depth from the bottom of a boat to the lake/pool bed between atleast 1m upwards to 20m range (As the min & max distances of the sonar are multiplied by 4 atleast according to this blog post
Has anyone had luck with these water resistant MaxBotix sensors underwater and if so can I see their code and hear their methods as I'm stumped.
Fortunately, even after applying the Silicone Sealant around the transducer to seal it, it still works just fine in open air with no loss in precision.

HI EVERYONE HERE.
I LIKED THE DISCUSSIONS GOING ON HERE AND I HOPE MY QUERIES WILL BE SATISFIED OVER HERE.
I AM MAKE AN AUTOMATED CONVEYOR BELT SYSTEM FOR MY FACTORY AND I HAVE TO MOVE THE FINAL PRODUCTS WITH SLOW AND CONSTANT SPEED. PLEASE HELP ME WITH CIRCUIT DESIGN WHICH HAS PWM CONTROL FOR DC MOTOR.
MY SPECIFICATIONS ARE AS UNDER.
MOTOR : 24 V DC MOTOR
MOTOR SPEED TO BE CONTROLLED IN THE RANGE OF 2 RPM TO 50 RPM.
IT'S 240 V AC SUPPLY IN INDIA AND HENCE AC DC ADAPTER .
HOW TO DESIGN CIRCUIT FOR THE WHOLE THING.

I'm curious as to the thoughts on cyber security for embedded Linux? How important is cyber security in your applications? What methods do you use?
I think this topic is going to become more important over time as the use of Linux becomes more pervasive in IoT, Robotics, and other embedded applications. Let's start a discussion.

For Dutch national television I am working on the research for a new TV-show about robots and AI. For this show we are looking for people who are very enthusiastic about robots. About building them, spending time with a robot or people who have a remarkable story to share about their experiences with robots. Do you know someone like this or do you have such a story to share? I would really like to hear them. You can post them here as a reply or send me a PM directly or mail me at j.koning(AT)vpro.nl.
Some info about the show if you're interested. Our show host is Jelle Brandt Corstius, a Dutch author and TV-journalist. He is curious to learn about the world in which his baby daughter will grow up. Will she date a robot? Will she still has to work in a job or has AI taken over most tasks? The show will have 6 episodes and we'll try to follow the course of life: birth, education, relationships, work, healthcare and death/immortality. The broadcast company is called VPRO and you can find info on the company here: http://www.vprobroadcast.com/

Hello people. It's been about 6 years since I last came on here, or indeed, played with robots.
About that time I made an ERP clone, but never got around to programming it, but have now finished construction and want to try some of John's ERP routines.
As time moves on, I am now using Windows 7 64bit, and am having trouble connecting to the Axon with Tera Term. (I haven't even got around to boot-loaders yet!!).
I have made sure the Port and speed (115200 baud) are the same on both, and the Axon lights up when I connect battery. But I get nothing on Tera Term.
Does anyone have any ideas? I have to say, I can't find the original USB lead that came with it, does that matter? ( Oh, as an aside, I'm using AVR Studio 4.18.716 )
Any help will be much appreciated, as I love the Axon 2.
