how to make a fling robot

Hey friends

i want to know how to make a robot fly since i can make simple robots . I want to make a robot which can fly at higher altitude

6 wire RC steering servo?

Hi All!

This is my first post so go easy on me. :)

I am trying to build an obstical avoidance robot and decide to salvage a chasis from an old Radio Shack RC truck. The main board is fried. when I got to the se=teering mechanism I discovered 6 wires coming form what I would think is a servo. I was expecting three wires so I'm not sure how to hook it up to my motor shield for an arduino.

I discovered that if I applied a voltage to two of the wires the wheels turn on direction and if I reverse them they go the other way.

How to program Dagu t'rex motor controller

I was just bought Dagu t'rex motor controller From Online i konw how to write sktch and how  to upload it on controller bu i dont have any idea about how to connect t'rex motor controller to Arduino Softwere. Do i need to connect t'rex motor controller via Arduno board or something like that??? 

Intel Edison Arduino Expansion ---> dymanixel motors

I was wondering what the best method to control DYNAMIXEL AX-18A motors from an Intel Edison with arduino expansion board would be, I have teh Arbotix-M, the UartSBee, the Edison with Arduino Expansion Board, and the Arduino Uno. I really want to make it so that I can use the Intel Edison w/ expansion board, and send that to the Arbotix-M. Can you help me?

 

How to build your first robot?

Dear: LMR

Just to let you know guys it wasn't that long ago I asked my Dad if we could start a robot club at school. My dad brought it up to my princible and he did not have a problem with it. This robot club is probably going to teach people in highschool to build there first robot. I have no idea what robot I am going to teach highschoolers to build.

DIY laser cutter

Reading about all those lucky people that have access to a laser cutter, i was wondering: can we make one? I mean, build a custom (cheap) laser cutter?

I think it should be something like a plotter, so with a couple of fine-grained steppers and a frame structure (maybe some old scanner) that should be ok.

The problem is the cutting :P where can one find a good laser? i thought about CD-Writer but they have about 100 mW.. I don't know, maybe it's enought for a small dark acrylic sheet.. But i think the optical stuff won't fit :)

Affordable 3D printer? (For small robotics)

Lately I've been getting frustrated with cutting, sanding and drilling wood. It takes lots of time and the quality is low. Im thinking a 3D printer is exactly what I need. Anything from the $300 to $500 range? Cheaper the better? 

Pi!!!

Just got my Raspberry Pi today :)

Can't wait to use it!

IN-16 Nixie Tubes on the way from Russia!!

 

So, I've been looking at these amazing tubes for some time now, and today I just bought six pieces... Straight from Russia!

 

18$ is what I had to give. Not bad at all.

I got them on Ebay. There was another offer, 100 tubes for 300$.. I almost hit the button, but sanity caught up with me :D Sadly!!

I love old tech!

Robotic Vision Question

Hey everyone,

I'm essentially building a glorified pan, tilt camera that will hopefully one day shoot a laser.  I was originally thinking about using a WIFI camera.  I was going to have the video stream sent to a laptop and imported into a JAVA application.  Now I've never done something like this.  My hopes is to have the robot controled remotely, and there is no onboard CPU, only an arduino controller.  I really dont want to use a USB webcam.

Does anyone have any suggestions?
