Let's Make Robots!

Just made my first SMD soldering

Today I made my first SMD soldering. This is where I started:

FT232RL and SSOP28 adapter

And this is what I ended up with:

Done!

Hi everybody! First of all, I want to thank all of you guys who's robot projects and blog entries make this site such an amazing place! You all ignited my passion … Read more
If your robot is inside another room, on the floor, has the board hidden within a tube, or you want wire contact while it's driving around on the floor..
Yes, I know that this is very, very basic, now that people here are making robots that flies into space, stereo vision, multi core and all.. But I just did this so … Read more

Mr. General sensor issue.

After getting the kit together, Mr.General just wont do as supposed! When looking throu a camera only two of the infrared sensors led up? I have had a electrician look at my soldering and he could not find anything wrong.

When turning it on all green led's shine brigthly, but after a few seconds it starts buzzing from the speaker and the green led's starts blinking with the buzzing. If i then touch the wiring on the breadboard the head starts to tweak, and sometimes the green led's get solid again. Have also tried to change all the wires. Still the same!??

Please help!

Walter can play rock/paper/scissors!

We're gettin' somewhere...

This is Walter "docking" or stopping inside of a given area. I should say that in the video, Walter comes up quite short on the target. This is an issue with the beacon, not Walter. Walter judges distance from the beacon by judging the "size" of the beacon within the view of the camera. --As he gets closer, the dot of light gets bigger. When you put nice, fresh batteries in the beacon, it becomes super-duper bright and thus, Walter thinks he is closer than he is. I just need to get around to doing a bit of "regulation" on that beacon...

Enjoy...

How to use HPWM for picaxe chips.

This information is based on the chip that is used for the 20x2(PIC18F14K22) To get a better understanding of the modes, I suggest referencing this datasheet for further information on the chips features. IMages and info are referenced from both the picaxe 2 manual and the PIC datasheet for the above mentioned chip.

HPWM, what is it?

Not all Arduino pins default to input!

Every now and then I come across a problem that takes a long time to solve. When I find the solution it is usually something very simple. I hope this will save someone else some time.

Today I am writting a program for testing the Spider controller. Since all the I/O pins connect directly to the processor there is not much that can go wrong. Basically the program just needs to check for short circuits and open circuits due to bad soldering or faults in the PCB.

Review: Ro-Bot-X uServotino

Introduction

Now, for the next in a series of reviews on Ro-Bot-X's boards. This one is on the beta version of the uServotino. It is an ATMEGA328 custom board with the Arduino bootloader pre-installed. 

The Kit

Ro-Bot-X's boards are usually available in three options.

A Complete Design and install solution of mechanical, hardware, electronics, plastic injection, installation and software. 4,250 pixels under glass floor, interactive using real time Vision analysis. Plays Videos. 20 Meters x 5 Meters. R&D and implementation of a suitable Image Processing Pipeline of Fisheye Transform, Affine, Population Threshold, Crop, Blob Size Filter, Smooth Hull, Blob Tracking and Replace of Blobs and show of statistics
