Brain storming

Engineers facing the world ...

Engineers believe they can fix everything and in case of failure, they are humble enough to accept carry the guilt personally and mention that it is them who can not solve the challenge, but a challenge always has a solution :-)

I like to be an engineer ;-)

:-S

I feel I got a lot to do ...

Nice quote ...

To solve any problem, here are three questions to ask yourself: 

- First, what could I do? - Second, what could I read? - And third, who could I ask?

Climbing patterns

Fast climbing with degrees from 0 - 360 degrees

Slow climbing with either upwards and downwards, or right and left

The combination of these two types of climbing can give a combination of very fast climbing plus precise climbing when needed. Also fast climbing method gives robot the chance to move to directions from 0 - 360 degrees.

Bluetooth Technology

Bluetooth uses very little energy !!! They are used in Tsunami detectors (ZIGBEE tech) ...

Advantages	Disadvantages
High throughput	Device discovery is slow in term of power usage and time
Resilience against interference	Keeping connections open is expensive in term of power usage

Infrared Technology

Using Infrared for connecting micro-controllers is one of the available choices of wireless intercommunication between micro-controllers. Here is a short list of challenges and the benefits that using such technology would provide us :
Advantages

• Very low power requirement, hence it is best suitable for machinery with limited battery capacity, like mobile robots, laptops, pads, phones, etc.
• Inexpensive -> Not a very important issue in designing a revolutionary system. The redundancy is the most important feature.
• Very secure. The data flow among the source and target is unidirectional, meaning the direction of the infrared beam ensures that there in no leaked or move to nearby devices as it’s transmitted. 

Disadvantages 

• Data transmission happens in eye sight. -> Meaning you can not have it in a big robot.
• Short range communication -> Actually this is an advantage in our case, which brings more security.
• Easily gets interrupted by obstacle  -> Meaning you can not have it in a robot with several layers between micro-controllers. Almost any kind of obstacle interrupt the signal.
• Not a good choice under extreme weather conditions(sunlight, rain, pollution etc) -> This is the most negative point for this technology not be used in an offshore robot.

Depending on the area of application Infrared might be or might not be the right choice. E.g. the short range of availability would increase our security a lot, while exactly in Walloid project the harsh weather condition is very common in future platforms. Today, there are many technologies exists that are much better than IR like Bluetooth, Wi-Fi etc.

Arduino boards LAN

A wild idea which I hope it's going to work ...
