We initially looked into the DFRobot 4WD Arduino Mobile Platform
because of its low cost and feature set. Ultimately we chose
another product instead. However, after doing an extensive review
of this product we realized that we made the wrong choice!
Once we received the DF Robot 4WD Arduino Mobile Platform we
quickly opened up and began the review process. What we noticed
right away when we opened the the kit that it had NO INSTRUCTIONS.
We were a bit thrown back because every kit we have ever used came
with instructions. Needless to say - we found that the reason why
was because the the kit was so straight forward one could do
without them.
Yet another thing we noticed is how much this platform resembled
another platform we have worked on (Lynxmotion). The kit is comes
with solid components and is easy to put together.
Overview
The DFRobot 4WD Arduino Mobile Platform provides a 4 wheel drive
system complete with 4 DC Motors. The DC Motors are not your
typical robotic actuators. Rather, they are basic DC motors that
can be picked up at your local Radio Shack for a few bucks a
pop!

Quick Review
Our aim here is to talk about the high level view of this robot
kit. We have created a video that quickly gets you up to speed with
the robot kit and makes everything clear. We are uploading our videos as we speak
Assembly and Construction
To make this part as easy and straight forward as possible we have
recorded a multi-part step by step video of how to assembly and
work with the DFRobot 4WD Arduino Mobile Platform.
The Kit
Support
We gave DFRobot a 4 for support. One of the main reasons is because
we have never needed any with their products. Imagine that. A
product that does not require support. We would have given them a 5
but we did not have the instructions included in the kit. Even
though the kit was easy to build - we think it would have been a
good idea to have the assembly instructions included. More
specifically when it came time to wire up the unit to the DFRobot
Arduino Romeo microcontroller. It was straight forward for us to
assembly - but may not be to the typical consumer.
Conclusion
Overall this is a great kit to get started with. This kit can be
used by beginners to advanced users. We truly thought the quality
of the construction of the kit was superb. Especially for the
price. You just can't beat it! We have yet to find any other
robotic platform on the market that is as good and broad as this
one for the money.
There are some some snags along the way you may encounter. Here is
just a few of the "snafoos" we found:
Missing Assembly Guide
Wiring the DC Motors
Wiring the DC Motors to the DFRobot Arduino Romeo
Mounting the DFRobot Arduino Romeo to the chassis
Thats about it. We recommend this kit as a good all around kit to
be used indoors only.
I have installed Arduino on my Fedora 17 system, but am having problems with some of thee header files and libraries being found. I guess I could do the compilation by han and pass in the includes and libraries, but would rather have arduino workin properly.I installed arduino using yum install arduino.I can get simple programs to compile as long as the don't need methods from other libraries or header files.Anyone know where the header and libraries get configured, i know of the ones in…See More
Before reaching the professional trader forex robot, it is important to understand how the forex market. It is also important to know why a robot to replace human operators. The robot kit is actually a script coded with a forex trading strategy. Forex is a big problem. But to summarize in a few words, what happens is that traders buy and sell currency pairs specific and make money from currency fluctuations respect. Buy a currency pair is called give and sell the position is output. This is…See More

Automated forex software is a very necessary piece of kit? One thing to keep in mind is that you need not use it before, why the sudden change? Take a look back in the days before the flash automated forex software. Fees vary considerably began after the fall of the Second World War, the Bretton Woods Monetary Stability Pact in 1970. The agreement had other major currencies pegged to the dollar, but fell after the decision of former President Nixon to take the U.S. dollar to the gold standard.…See More

Not quite sure what to make about these little guys. But you gotta admit there is some appeal to their appearance. Maybe they are viable telepresence or security watchdogs per say for organizations. Or maybe just some other cool robot that does not spectacular.See More
Always buy a remote controlled helicopter with a minimum of 4 channels - whatever less makes it hard to operate and wont fly in all directions. 4 channels are more inspiring but once you have got the hang of it the flying palpate is a thousand times great and will stand you in good stead should you ever wish to move to a more advanced helicopter. advanced models being 6 channels or more can be the next step up or a first purchase when you have adequate support. Buy a helicopter with good back…See More
As if we didn't have enough. These robo-boats do a rescue mission. The use of a Traxxas pick up RC car, a custom QUAD Copter, a few robot boats with a platform top - and to top this all off KEN - Barbies hubby. The robots links together and have ballasts to maintain stability. Its pretty impressive. Reminds me of the replicators for Star Gate. See More
