Hi , here we go for a new hackerspace in Pitesti , Romania and we have already a place for working but we need money for tools
So we started a campaign on Indiegogo for financing this , maybe you can help!!!
Please like an share , you can help.
Hi, LMRians. I've been reading up on this Wavefront Algorithm Navigation and I understand bits and pieces of it, but not everything. I'm trying to learn up on it so I can use it in my next robot : Project 4L-FRED (Alfred), a butler robot. The robot is suppose to navigate around the house from the dining area to the living room and serve drinks to guests. The robot will have pre-recorded messages like greetings and stuff like asking what drinks the guest would prefer.
Hi all.
I am really new to robotics, and only just recently got my arduino uno. i've played around a bit here and there to learn how to control servo's and such, so i figured it's time for me to build my first robot. but in the design, i've come across a few problems:
I've picked up an arduino to start working with, and have currently slung together a bit of code to toggle the on-board LED over serial. I've also modified one of the Processing demos to use as a GUI to turn it on and off. However, my arduino is on COM6, and if I try to change the port on Processing to anything other than 0, it comes up with an error. I know the arduino code works, as I've tried it with the arduino serial terminal, however the processing app doesn't want to play ball.
Looking for a way to network enable your Arduino projects without wires? Look no further, you need the Arduino WiFi Shield available in the Maker Shed! This shield fits atop your Arduino and will connect to an 802.11b/g network with relative ease. The shield comes completely assembled and uses pass [...]
This polar graph draws some amazing shapes on a dry erase board. Part of that is due to the mounting brackets used for the two stepper motors and the stylus. But credit is also due for the code which takes velocity into account in order to plan for the next set of movements.
The Go language is used to translate data into step commands for the two motors. This stream of commands is fed over a serial connection between the RPi board and an Arduino. The Arduino simply pushes the steps to the motor controllers. The inclusion of the RPi provides the horsepower needed to make such smooth designs. This is explained in the second half of [Brandon Green's] post. The technique uses constant acceleration, speed, and deceleration for most cases which prevents any kind of oscillation in the hanging stylus. But there are also contingencies used when there is not enough room to accelerate or decelerate smoothly.
You can catch a very short clip of the hardware drawing a tight spiral in the video embedded after the break.
Hello again everyone, my name is chickenparmi.
As suggested by ChuckCrunch I am making this blog post to give you a brief explanation of my past experience/knowledge in robotics and all the things I have made. I will post all my old stuff in this blog and stuff that I dont think to be worthy of a robot post as to avoid post spam.
It's a nice shop for getting some inexpensive robot kits like some arduino stuff.Maybe the customer service there isn't that good at robots,but the products they sell are great.
Let me introduce you to my Moth Car! The Moth Car is made from the chassis of an old RC car I found out in the shed. Forgotten and deteriorating away I decided to give it a new life.
I carefully de-soldered the wires from the battery pack and DC motors and kept the receiver for another day. Using the Adafruit motor shield for the Arduino Uno I connected the cables. Making sure that everything was connected properly and operational I uploaded some test code and thankfully it all worked.
Rebuilt my lucky cat: whenever a page of my website is loaded, the cat will be waving its arm. There’s a light sensor so when its dark, the cats RGB-LED is changing the color instead of waving the arm. Changing the color of the LED is also possible with one of the buttons on the cats ears. The other one is the reset button. Used an arduino ethernet, a servo, two buttons, an RGB LED and two small yellow LEDs. The seven segment display is one that I harvested from an old stereo. It’s driven by the arduino and two shift registers. unfortunately I’ve soldered that one together for an older project, so that it doesn’t fit into the cat too. It shows the number of pageviews of the website.
