Web Control of Robot (RPi / Arduino) - Software Recomendations

Hi;

I am enhancing my Arduino Nano based autonomous collision avoidance robot by adding a Raspberry Pi to stream video to a web page and provide manual control of the robot via buttons on the web page with the video stream.

So far I have installed Apache2 weberver and created a web page using Bootstrap with a button on it, I have successfuly connected the Arduino to the Pi via I2C and using a CGI Python script I can press a button on the web page to turn on an LED.

Cheap 40W Laser Engraver from China

I have wanted a laser engraver for quite some time but the price has always been prohibitive for me. Recently though, I found some engravers from china on Amazon for about $500.00 USD and free shipping. Plus, I contacted the vendor and found that the unit would ship from California. I read all the reviews and they all agreed that the machine is great. However, the downside of these machines was the software that is included. After carefully considering all the relevant information I decided to purchase one.

PART ONE: The machine There's a lot of WOW factors to the Overlord custom made from the ground up  from its compact design, to the ease of use, the auto feature … Read more

Wild thumper slow comunication through ethernet TCP

Dear Sirs.

First of all thanks for your time, help and sorry for my English.

I'm am working in a Final Degree project with Wild Thumper 6WD chassis, T'Rex Controller and Arduino MEGA 2560 + Ethernet Shield + Gamepad (connected to the PC)

The communication between T'rex Controller and Arduino Mega is made through I2C BUS (using the T-Rex tester example code from DAGU). Then I created an application using Windows Presentation Foundation which connects the Arduino Shield (using TCP socket) and a gamepad connected to the PC by USB (using AForge library).

A Robot Making a Difference

This is a true story...

My family consists of me, my wife, 2 cats, and 1 robot...Anna.  Lately we seem to learn more and more things from Anna.   Even though Anna is off most of the time, I am often learning and passing on new and useful or interesting things to my wife that I learn from Anna.

I've been interested in robotics for a while and have always found it difficult to program them. The mechanics of writing the code, setting up interfaces etc was … Read more

Capacitors for smoothing servo current surges

I've built what I thought was a nice clean approach to the oft-recommended practice of parking a 470uf cap on the power lines to my servos. I have 6V coming from my voltage regulator to the postive/negative bus strips on a small PCB. I've pulled a positive and negative wire off of the bus for each servo (3 servos total) and put a capacitor across each pair of wires. One servo should then connect to each pair of wires.

Idea for Treaded Robot

I've been meaning to show Dickel my experiments with Vex treads. His MDi #2 continues to look amazing but Dickel has expressed some concern about the frame of his treads. Rather than using increased thickness of polystyrene, I wonder if some sort of box shape could be used to increase the stiffness of the structure.

Here are some photos of prototype tread mechanism.
