Adeept Mars Rover PiCar-B Smart Robot Car Kit for Raspberry Pi 4 3 Model B+ B, Speech Recognition, OpenCV, Real-time Video Transmission, STEM Educational Robot with PDF

Mars Rover Picar-B - It's an amazing kit. I have had need to contact support twice and they answered my emails within a few hours. Be aware it is not a snap together remote car that will do cute tricks. The kit itself is of high quality and took me an afternoon to put together. Look on the Adeept for the PDF tutorial on how to put it together and also the video on YouTube - consulting them side by side helped me to put it together no problems. There are batteries for it on Amazon and you of course do need a Raspberry Pi to make it work - the Raspberry Pi 4 with Buster works fine. Now I have it installed and working the fun starts. I will do basic stuff "out of the box" but the idea is to learn to program in Python to make it do load more stuff. If you are after a learning project. 100% recommend

I built the Mars Rover PiCar-B and the problem is that the sensor head (the big head with the Ultrasound and camera) starts to rattle around as soon as it moves, only holding it or moving to the end of the servo movement stops it. It's like the servos can't hold it in position, it also makes the impression it is not very stable on top on that one tiny servo, which seems to be overwhelmed with it.I've now bought myself upgraded servos, or better said "suitable servos". The servos in the box seem to be either fake Tower Pro, or absolutely overwhelmed with this robot car.I've tested the servos with a servo tester, one was already broken and probably caused more pain for the other one in the head. If I wouldn't love to build those things, I would be super angry about such a low quality, or let's say unfit for purpose part in this kit, because I had a lot more hours to make it work! The new servos are from the same manufacturer "Tower Pro" but the model is the MG90D, with a lot more power, metal gear and digital, so very precise.I paid £7 per servo, so that was an extra £21, but now I can have a calm mind and work properly with this robot car. If other models are equipped with the same low quality, I would think twice before I buy, and if only with a discount so I can pay for the other servos.Hope this helps others!

If you’re expecting to receive this and have all clear instructions and an easy set up guide with everything working quickly and easily… this is not the kit for you. I know it’s not much to ask for in this day and age, even for a cheap kit but I would recommend it still. I’m an engineer and it gave me a few head scratching moments but someone with patience will get through it. Read some Q&A when you get stuck, the end result is good. I had a couple of broken bits of plastic but was easy to fix. The one that surprised me was all three servos supplied where all faulty. I didn’t even think to check them before installing them and once I tried a test program, thought I must be doing something wrong. I had a servo tester and sure enough, all three not working. Either not moving, moving very slowly with no power or jittering over to one side. I bought a pack of SG90 servos (the size used for this kit) and tested them first before installing, then all good.Installation instructions and software setup instructions are on the adeept.com website. I found using a combination of using the V1 and V2 instructions to build it as although they not 100% the same, they are close enough and between the two instructions to work out what to do. When it comes to the software for the raspberry pi (which you need to supply) one set says to install the latest version of raspbian but the adeept software hasn’t been updated for the way the camera system is handled in the new version. You need to install raspbian 2021-5-07 for the software to work with the car correctly.That said, once it’s done, it is very good and works well, great for plenty of AI and robotic experiments.

This is the second robot kit I bought in Adeept. I completed the construction bit by bit within a week, and it took about 10 hours in total. During the process, I encountered some problems, but I overcame them and gradually completed the projection finally. I gained a great sense of accomplishment from the manual, but I have to say that there are some spelling errors in it, though it is correct in general.

Was looking forward to this as a present to my son.The instructions contain spelling mistakes, incorrect diagrams/pictures and broken links. The kit parts do not match the instructions and the YouTube instructions video is miss out building steps/parts - deliberately I suspect. All round disappointing purchase. Avoid adeept products in the future and at all cost!

I am buying it for some machine learning applications.There are many pi rovers for home projects. However, this is one of the best made and documented products at this price range. I spent one evening assembling all parts and ran several tests. All components worked for the first time. I had great fun while doing it.The product does not come with a manual. However, you can simply google the "adeept mars rover-b" and find the PDF version. Remember to use *the 2nd version* of the manual which fixed many typos in the 1st version. The document is reasonably well-written and in hindsight, many of my problems could have been avoided if I had followed the manual at the beginning.I would also recommend connecting all motors/LEDs to the control board to have a "dry run" before the full assembly, which saves you the trouble of disassembling later.The structure is also very robust. My pi-car fell off from my desktop (75cm) and only one servo motor suffered slight damage (which is then fixed using the provided spare motor).
