Smart Robot Car Kit for Raspberry Pi 5/3B/3B+/4B,Upgraded AI Visual Color,QR Code,Face Recognition,Line Tracking,Obstacle Avoidance,Electronic DIY Kit for Teens and Adults(Raspberry Pi Not Included)

The instructions were a little terse, however there was a video provided by the manufacturer that my kids and I were able to easily follow along with to complete the assembly. I did have to splice a few of the black wires from the right wheel motors to the arduino so that they would reach. I may have done something wrong, but the default camera angle at start up is always a bit weird-- something I have to readjust every time we use it. Overall we've had a great time with it, and our dog loves chasing it.

Assembly written Instructions for this toy were too small and not clear and all on ONE PAGE totally not acceptable. And the DVD for additional instructions did not load even from two different machines. You're better off buying it assembled because during testing you never know if you put the hardware together the wrong or a programing problem Python or an operating system problem that was loaded wrong. So you could end up with a TRIPLE PROBLEM.

I'd like to use this review to leave some helpful tips to others who wish to buy the product.First, know that the assembly instructions that come with the robot are essentially a link to a YouTube video, in which a woman assembles the robot from start to finish. There are some subtitles to help you understand what's going on. It's about 28 minutes long, but it took me roughly 4 hours to complete the assembly. Not too bad, considering it was my first time.When you're finished, you'll want to download the app to use the robot. I used the one for iOS, so I can't speak for the Android or Windows clients. The app could use some work, to be fair. It has a 5 second ad when launched, which is annoying (I may write my own when I get time). But, if all goes well, you'll connect to the Robot's WiFi hotspot, launch the app, and be able to connect and tell it to move with the joystick controls. Unless you miraculously wired up each motor the right terminal, you may find that Forward goes to the Right, Backwards goes Forward, etc. You'll need to calibrate those by adjusting the command "strings" in the app. These are hexadecimal strings, such as FF000100FF. Change the digits 1, 2, 3, and 4 around until they match up with how you wired it.As you dig in, you'll find the video feed is pretty cool, but the camera may have the correct angles. Ensure the servo components are align right so that the camera can freely move all the way to the left and all the way to the right (90 degrees). Additionally, it may not tilt all the way forward. Fear not! The camera itself sits on a socket swivel that you can manually adjust, independent of the servo motors.At some point in your adventures, you may even want to write some Python code to control your robot. You'll need to SSH into your raspberry pi, using [email protected] (assuming your laptop is connected to the robot's wifi hotspot). Alternatively, hook up an HDMI cable and keyboard to the raspberry pi and manually log in to the Ubuntu desktop that was installed. Note, I changed the language and locale to be English. I also reset "root" and "pi" password here, so I can't be sure what the originals were. The instruction manual had one printed, but I don't know if it was accurate.Anyway, at this point, you may discover the "follow line" and "avoid obstacles" menu options and python scripts. You'll need additional sensors for those:(1) https://www.amazon.com/gp/product/B078TZRGXF/ref=ppx_yo_dt_b_asin_title_o01__o00_s00?ie=UTF8&psc=1(2) https://www.amazon.com/gp/product/B07B94C7KT/ref=ppx_yo_dt_b_asin_title_o01__o00_s01?ie=UTF8&psc=1(3) https://www.amazon.com/gp/product/B07GD2BWPY/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1Item (1) are the IR sensors, which will allow you to follow black lines on light surfaces. When it arrives, you screw those into the front holes, and connect via ribbon cables, to your IR_L and IR_R pins. You'll need to adjust the screw on each one to the distance the IR sensor wishes to measure. Turn the screw until the red light no longer detects darkness on your floor.Item (2) are the ultrasonic sensors, of which you only need one. However, you'll need the cables from item (3) to attach it correctly to your pins 17/4. The sensor itself can be mounted on the same piece that holds the camera.Overall, the price point on this robot was perfect for my needs. I can drive it around with my phone, can view what it sees, and I can write python code to self drive it, if I want to. Very cool toy for the price, and I'm overall happy with the choice I made and the learning experience. The vendor is very responsive, too.

Took me a few hours to assemble, then a few months to get connected to my phone. There are definitely better options at a similar price. Here are the tricks that helped me. Its probably obvious if you can read the documentation.- The robot is the wifi hot spot.- The robot comes with a CD that has the APK you need to connect to the robot on it. If you download the one from Google Play or where ever you'll likely get one that works with the platform but not the robot which means you'll see the webcam output but won't be able to control the vehicle. Use the APK from the DVD.Additional Notes: I was missing plastic mounting parts, I had extras of many, but lacked some that I needed. I bought a pack of cheap generic mount parts and that worked.Wheel connectivity is tricky to see in the video, but I used visual markers on the motors to figure out which wire was which and managed to get it right first try.

5 star for over all product and customer support.Product is detailed in the description, nothing is left out. You get what you get. I do not recommend this for novices. Like one of the other reviews if you are a beginner you will have a little bit of a challenge. I had a challenge with the provided CD because who uses CD's these days? They have a dropbox support for whats on the CD which was great. The only other issue I had was either the IMG file or the WinDisk Imager would crash at 5% during the imaging process. I had to use Etcher on my Mac(Mac support is not available from the dropbox provided) which then the IMG was able to be put on the provided SD card. Assembly is pretty straight forward, product is sturdy and leaves you options to add on which is nice.Customer Support is incredibly helpful. They will answer all your questions as needed. There is a grammar problem but its not an issue, they are able to help and explain the issue clear. With all my issues from above they assisted in a timely manner and pointed me in the directions to resolve my issues.The only con I'd have to say is the paper document they provide with all the info in terms of setting up and wifi info is that the font is so friggin small its hard to read. I am not nearsighted. The only way I could read it was to take a picture of it on my phone and zoom in on it.

If you are a novice to electronics, the info in this product's write up is very deceiving. It is worthless without the Raspberry motherboard! The camera that comes with the kit will not work without the motherboard, in fact nothing works without it! The pictures all show the motherboard and even some of the questions allude to the fact that the mother board is included.The serrvice department is VERY responsive, sometimes within minutes, but without the mother board nothing helps. Also, I've started getting spam type emails from companies like this one after service contact.
