This kit is awesome save a few issues. The quality is very high. Everything fits as promised. The best part and worst part are the instructions. The build instructions are pretty good. Few times you have to look closely at what to do but it was easy enough. The CD that comes with the kit is broken down into sections. One section is the build and the others are about the software with sample programs. They even include videos showing it working with each software loaded. If you follow the instructions exactly some of the programs will work and others will not. The problem is that the hardware and software don't line up which I will explain later.

If you have never built a kit like this before it can be daunting. If you stumble on the technical issues or try and use some advanced features most people will NOT be able to get this to work as they are nuanced issues with how an Arduino works. Let me explain

Technical problem and FIX: The issue is around the motor drivers. They have the motors tied to pins 5,6,7,8,9 and 10. 5 and 10 control the speed of each side and 6-9 control the motor direction. If you just use pins 5 and 10 to go full speed using a digital "HIGH" setting then everything will work. The issue is that this speed is too fast for some things and not as fun as variable speeds. If you try to control the speed using PWM and a setting below 255(0-255) it will not work. This is easily found in the wall avoidance(maze) sample code. It has the car go slow using analog PWM on pins 5 and 10 so it doesn't go so fast that it cannot avoid an obstacle. When you slow it down using PWM on a digital pin 10 AND try and use the servo library you have an issue. Int his case the servo library is used to control the "eyes" to see the walls.

New review. I had the opportunity to test out the updated version of this product and to do a direct comparison to the previous, which I already own.
The Pros: The mounting plates used are now both made from a thick acrylic. All of the parts come in neatly labeled packaging and the instructions include high quality photos. The batteries have been upgraded to two 7.4Wh Li-ion that fit smoothly into cell box. The ArduinoUno R3 works great but you may need to unplug any extra peripherals before flashing codes to it. The included Sensor Shield has several unused pins which means there is plenty of room for your own additions to your build. Everything you need to make this project work, including Arduino example libraries, are in an impressively packed little container. The Elegoo Support Team is very helpful and responsive to concerns.

The Cons: I would rate the necessary experience level at about a 2 or 2.5 out of 5. A novice with patience can do it but having at least some knowledge of what the parts are and how to put them together may come in handy. If you can sort through instructions then you will likely do fine. If you have OCD you may need to be patient while looking through the literature, as the instructions are translated into English and can occasionally seem short or direct. The pictures definitely helped me more than the written but that is not to say that they are bad. More-so that I am a perfectionist.

Conclusion: I have been enjoying this project and it has made learning about Arduinos and programming more interesting to me. I get to write code and then see my progress work on a physical machine instead of just a screen. While toying with the IR codes I changed one "if" to a "while" and turned my smartcar into a remote controlled IR car. Apparently the car was having to much fun driving itself so I needed to take control back. Anyways hope this update helps.

This is a great little kit for someone who is wanting to get started with programming an Arduino and learning how to use analog sensors such as sonar and line followers. When I opened the box I was impressed with the quantity of parts that were included. The kit assembled easily with what I thought were some pretty decent instructions on the CD that was included. I do wish that they had a sheet of paper with a link to some downloadable instructions along with the CD since I use a MacBook Air and do not have a CD drive. It was a hassle borrowing my wife's computer to copy the files to a jump drive so I could open them on my computer.

I assembled the robot in one evening, after celebrating by birthday with a few beers at dinner, so it cant be that hard. The one thing I did not like was that the motor control board, the Uno, and the infrared sensor all mounted directly the robot cars chassis and with various lengths of soldered legs sticking through the bottom of these circuit boards they all mounted out of level, and would crack the printed circuit boards if tightened too much. I used side cutters to trim the protrusions on the bottom side of the motor control board because it was a detail that was bothering me, but I would not expect most people to do that. This issue could be corrected by providing stand-offs like they included for mounting the line followers.

The teaching modules for programming are okay, but could use a bit more elaboration for beginners, I would also recommend trying Modkit Micro for a Scratch based drag and drop programming language that will work with the Arduino.
