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. 


T'REX robot controller


The T'REX robot controller makes controlling robots easy!

The Arduino compatible controller comes pre-programmed with sample code that lets you control it with a supplied Android app, Radio Control or with an external controller via I²C.


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:


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?

Practical Uses of Artificial Neural Nets?

I have read over the theory behind neural networks and found open source code to help implement them in various ways.

I was wondering if any LMR users out there had put neural nets to any practical uses on their projects?  What kind of neural net did you implement?  For what purposes?  Was it worth the effort?  What problems in robotics do you think are well suited to neural nets?

Hello guys,

Some of you might know that I had submitted my entry as part of the Village to Raise a Child Campaign. It's about changing the way Nepal learns through building robots.

The campaign has reached the voting phase and I am in need of your support.

T'REX tank chassis

It's been a long time coming but the T'REX robot chassis is here!

I've just been testing the final product so I thought I would post a few photos of the new chassis. The chassis is aluminium with a black powder coating. The tracks and struts are zinc with a black anodized finish. The wheels are zinc with a chrome finish.
