ELEGOO Smart Robot Car Kit Compatible with Arduino IDE with UNO R3 Board, Robot Toys for Kids age 8+, Educational Science kits Programming for Boys Girls Adults

Arduino Based Smart Car, with a huge range of features 🙂
Teaching Artificial Intelligence at Undergraduate level and seeing many student projects involving Robotic Cars, I was curious what this Kit by Elegoo would be capable of for the money, and whether I could potentially use it for teaching purposes, or for helping my Children (6 and 8 years of Age) understand how these “SMART” cars work.So I was excited to get started with the Elegoo ROBOT CAR Kit (SMART) V2.0 when it arrived.Upon receiving the kit, I noticed how well made the box was that the kit came in (as shown in Figure 1). Having bought kit before from other manufactures wrapped in plastic, or just put inside a jiffy bag, it was nice to see this kit securely and safely housed inside a bright orange box.Upon opening the box, I was pleasantly surprised to see a very well packaged kit, with key components such as the all-important Arduino board wrapped in anti-static bags to prevent them getting damaged by electrostatic voltages. Also inside was a nice key to contents in the lid, and a CD ROM ready for me to use as shown in Figure 2.Assembling the CarInserting the CD I opened “Lesson 0 Assemble The Car” and proceeded to build the car.The care took approximately 52 mins for me to build, and at times I had to double check the instructions as at times they were slightly unclear, but still 52 minutes to assemble the car seemed reasonable to me, I’m comparing this to a Lego Robot I built recently that took me 2+ hrs . The completed car can be seen in Figure 3.Making the Car Move Backwards & Forwards**************************I started with the “Make The Car Move” tutorial but quickly realised the batteries supplied were flat, I’m not sure if I was a novice user I would notice that, but the car just won’t work if the batteries are not charged. So best to put these on charge when you first unpack the kit (You cannot use standard batteries). Also though it says in the lesson to unplug the Bluetooth module when uploading a program, it is very easy to forget to do this and as such the program won’t send to the Arduino. So I had to unplug the Bluetooth each time I wanted to upload a program.• So I charged the battery.• Opened up the Arduino program (Sketch)• Ran the sample code• Happily, the car quite happily moved backwards and forwards which was good • I pressed the rest button on the board when I had seen enough The lesson itself is actually very detailed on how the motor driver works and so is definitely worth a read.Making the Car Move Bluetooth**************************I suspect me along with most users are going to find it long winded to get the .apk file from the disc onto the android phone, as such it would have been helpful to have put an app inventor QR code, an app inventor program or simply a google store application up for me to download. As such I skipped this lesson.Making the Car Move Infra-red.**************************For this I needed to unzip the 2 libraries included “Arduino-IRremote” & “IRremote” and put them into the libraries folder of the Arduino software on my PC.After running the software, I realised the car moves quite quickly as such, it would be really helpful if the example code made the car move a lot slower, which is easily possible, but less so for a novice user I noticed that unless the remote was pointed exactly at the infrared receiver, I got some random results and nothing seemed to happen, I found this out by opening the Serial port on the PC and watched what was happening.Making the car move obstacle avoidance**********************************I uploaded this to the car and put a bin in front of the robot, nicely it scanned, backed away, but then carried on backwards. I can see what it is trying to do, and It’s a Robot Kit so I’m happy to experiment with the software to get this to behave the way I think it should, but It would certainly have put off other users.So My Final Thoughts.******************I have lots of robots from the toy shop that work as I would expect out of the box, and they are fine to experiment with. But this isn’t a toy! It was a different proposition for me, I wanted a kit that I could build and learn from, a kit I could experiment with and be able to improve myself over time with code, and I think that is where this kit excels. If I was after something that assembled into a final car that just worked without any coding then this would be something I wouldn’t buy, but as an electronics, software, robot buggy development kit I really liked it. With some time and patience, it’s a lovely piece of technology for the adventurous electronics/robotic hobbyist to work with an Arduino based Robot Car. Sure the instructions could be improved on for assembly, the speed could be reduced, and an App could be available on the Android store to make it easier to control, but they are things I can do myself, and do quite easily with a little experimentation. Debugging is easy if users are happy using the Serial Window in the Arduino Sketch, and it would be good to see a tutorial to allow users to work through an example in case the car doesn’t work.Overall I would recommend this to a friend, and even get a few more to see if they could work together.The kit is controlled by the Arduino Uno, and this is an excellent embedded board to learn on as it is very versatile.
