How to make two way communication between Arduino and C#

Hi Guys,

I have been trying to get the value of a few sensors on C# from Arduino and pass a value from C# to arduino for a motor. That is 

Sensors---> Arduino ----> C#

&

C#---> Arduino --- > Motor

I am able to do these two things individually, but not together. The reason being that the serial is able to hold only one set of data at a time. Is there a solution to it, or will it be that I will have to use one arduino for sending and one arduino for receiving the data. Please help me through this situation. 

Thanks,

Wafers handling robotics arms

Hi to all the forum members, my questions for this tread are correlated to the robotics arms for wafers like the robotics arms that are in this website:

www.kensingtonlabs.com

1. why is so important to build very very accuracy robotics arms, Wafer Handling Systems , in the machines of semiconductors industry that arrive to 1 micro meter accuracy? in other words why the semiconductors industries invest a lot of money in research and development of very very accuracy robotics arms? and how it will make the chips for the CPU of the computers or smartphones better?

ComMotion Shield for omni and mecanum wheel robots

After building my first omni wheel robot I realized how difficult it can be to monitor 4 encoders and drive 4 motors so I designed the ComMotion shield. As the name suggest the shield is designed for motion control but as I ended up with 2 spare serial ports I decided to add communications abilities to the shield hence the name ComMotion.

Easily create a linear slide motion

You can now build linear slides with our Actobotic beams and gear racks!

Picaxe Programming HELP!!

Hi guys, if someone coud make a sample picaxe program for me to use and message it or post it in this forum it woud be greatly appreciated, as i cannot find a program for my system anywhere.

Accelerometer.. Which to buy?

I wanna get an accelerometer for my bot.

Need help with Rover 5 robot

 

I had Rover 5 robot with dimensions below

 

Gearbox ratio: 86.8:1

Encoder type: Quadrature

Encoder resolution: 1000 state changes per 3 wheel rotations

 

Can I build any other robot types with this kit?

I recently got the make: it robotics starter kit but I was wondering it there any other things I can create with the starter kit only and maybe a few extra parts? The two robots are kind of boring now. I have provided the Radio Shack link so you can see the parts it comes with!

A history lesson

 

I took these video's to show school kids a piece of history. But I thought you guys would find them interesting as well. Since we are a technology based group:

 

Using the INT pin on a DS3231SN to power/kill an arduino

Hello all,

First off, let me thank Geir Andersen and Oddbot for their excellent work on datalogging shields, mosfet circuitry and other answers to my silent questions, reading through the articles was great fn and a good learning experience.

Presently, I'm trying to make an Arduino datalogger based around the Arduino Pro Mini, running 8Mhz on an external crystal/resonator. This, in conjunction with an LDO regulator, SD card and RTC should allow me to build a logger and lo and behold, it works!

Inverse kinematics

Been trying to understand inverse kinematics for programming my quadruped Crap-Crab. I started out by reading Wikipedia's version, which lost me completely (WTF?). But then I found the explanation by this guy and it turns out, as I thought to begin with, that it's simply a matter of applied trigonometry.

Here is exactly what I need in a nutshell:

Arduino / ultra sonic sensor

I have not posted for a while good 2-3 years now as feel of ladder broke back,ribssss,concussion,blood clot spinal cord long time recovering but up and about now.Night mare few years

Trying to get back  robot building again,

having problems with Arduino Uno an my ultra sonic sensor HC-SRO4 

The program i used before does not seem to run them any more.

I have updated my libary with Newping...

Hexapod queries

Hi everyone,

I have been thinking of building a remote controlled hexapod from scratch including the code. However having never built anything like it and having basically no experience with arduino, I have a number of querys I would like your opinions on.

A robot shop in a van?

I'm curious. If I were to choose to be living in a van, how much of a robot shop could I take with me in a usable form?

I'm talking general tools including basic woodworking and metalworking. A 3d printer goes without saying.

And yes, I'd need enough space left over to live and perhaps even entertain in.

The budget for this thought experiment is $50,000 US and includes the large van or small Winnebago. At most two people would have to live and work in this. Any help in figuring out if this is possible and how to do it would be appreciated.

How to change the robot direction in Picaxe

Hello everyone ,

                I am new to picaxe , i am making a two and a three whell robot , i am stuck in a problem of rotating the robot body to other directions using picaxe commands . I need some help .
