Model 3 Robot Car DIY Starter Kit for Arduino UNO R3, STEM Robotics

We like the set and that everything is included with some really neat sensors! Some of the code has needed slight tweaking which adds to the learning or the pin diagram differs slightly from the video lesson. (We have currently completed through lesson 4 in update we are now at lesson 6) In lesson 1: the pin set up for the IR sensor differed between the video and the diagram (we followed the diagram) and it worked great. Lesson 3: the line sensor attachment has 3 sensors to follow a line. Our middle sensor was overly sensitive and causing it to have trouble reading both a single line of electrical tape on the kitchen floor and double so we erased the coding lines given for it in the lesson so only the left and right sensor are giving input. And it works great. It will follow a circle and a zig zag. We erased: "sensor_center = digitalRead (Center_Pin);" and "pinMode(Center_Pin, INPUT);" Lesson 4: we had trouble locating where to connect the pins (again the diagram and video can be different). This set is absolutely worth the money and our time! "Trouble shooting" with my son, age 13, is helping him to learn coding in a very affective way. I have no prior experience with Arduino and no coding (except a basic highschool course 26 years ago). My son, as stated, is 13 and this is his first time experimenting in coding, in robotics, and in Arduino. I highly recommend this set. I trusted the company because their 4 wheel set has good reviews but I needed to cut our Christmas expenses. I'm so glad we took a chance! Update: In experimenting with the correct wiring of the robot (lesson 4-5) and taking the battery in and out so much, the male side of the battery attachment detached from its plastic case. We kept going with the lessons because the battery still attached and "seemed" to work but we were getting errors gallor. Through working with John in customer service at Osoyoo Canada office he trouble shooted the problem and fixed (and upgraded our battery attachment). Without his help we weren't sure if there was a short somewhere or how to fix the little robot. We emailed back and forth and they offered a refund through Amazon and an entirely new kit or to mail it up to them and have them trouble shoot. We opted to pay to have it shipped and get some help. My son is very proud of his little robot and it was worth not giving up. John was very easy to work with. Osoyoo supports their customers and products 100%.

Bought Model 3 Robot Car, somehow the car only has one side motor span, I was guessing that Model -X Motor Driver might be something wrong, so wrote to Osoyoo customer support email box described the problem. To be honest, I didn't expect they will take a look, or they might take a look, but could be couple weeks or a month. Instead, they replied within couple hours, the gentleman John wrote me back and asked me to have couple tries. With the trial result, he decided to mail me a new replacement board. The new board solved problem immediately. Was very impressed by Osoyoo customer support staff, they are fast and efficient , they are the best. Thanks John.

The first two lessons went very well. However, on lesson 3 (line following) by the time we have it calibrated the 9v battery doesn't have enough power to drive the motors. We have double checked all of the wiring, it's all good. I'm using brand new Duracell batteries and I've gone through 4 of them already - I have build an Arduino robot similar to this and had no problems, my guess is the combination of the power drain of the 5 channel IR sensor, the motor driver, and the 2 motors is too much for a 9v transistor battery to drive. Update: After consultation, I used one of their rechargeable 9v batteries, wow, what a difference! I bumped up review from 2 to 4 stars, make sure you use their battery.

Easy to assemble, though the instructions were a bit misleading in a couple places. Works great, just as advertised...

I helped my grandson build a 4 wheel robot, and it was such a fun project that I bought this one for myself. The Elegoo 4 wheeled version ($89) was well documented with a nice assembly booklet and it came with the code installed. Everything worked well. You could change the robot programs with a push of a button on the remote or the phone app. This osoyoo 2 wheeled robot had no assembly instructions. There were links to instructions but they were for an older version with different components. I searched YouTube and finally found some terrible videos that matched the components for this one. They were not well documented and you have to install different programs to the Arduino for each of the robot functions. So if you want follow me mode, you have to download one program, if you want obstacle avoidance, another program, etc. The robot itself veers to the left while running. When you push the buttons on the remote, it only jumps a short distance, then you have to press it again. Pitiful programming. I was very disappointed, especially after having such a good experience with the Elegoo robot. This osoyoo robot is a complete waste of time.

It’s better to go to YouTube and learn how to build it then what it comes with

Easy to build and good start off project

Pro: - Good value for the money in parts alone - Uses well documented hardware so parts can be reused and reconfigured - Well written tutorials Con: - Code needed to be partly rewritten because it used a lot of unnecessary resources.

Ich habe den Bausatz für mich gekauft, bin schon Rentner. Ich habe Vorkenntnisse im Programmieren, war 20 Jahre lang Programmierer. Meine Windows Software hat automatisch bei der Installation des Robotfahrzeugs auf Deutsch übersetzt, ich konnte es also problemlos zusammen bauen. Was ich ein wenig doof fand, daß keinerlei Beschreibung zu den angeschlossenen Shields dabei war. Muss man sich wahrscheinlich selbst drum kümmern. Bei den Codes gibt es manchmal Fehler, sind aber nicht schlimm. Durch Fehler lernt man am schnellsten. Alles in allem absolut zu empfehlen. Der Plexiglas Geräteträger lässt sich mit etwas Geschick auch verändern, so dass noch mehr Sensoren oder ev. ein Greifarm installierbar wird. Es ist dann halt DIY. Aber dafür habe ich es ja gekauft.

Easy to follow instructions on line. Not too complicated but enough to intrest the young.

Mio figlio l'ho fa usato per un progetto scolastico abbastanza facile da montare problemi nella programmazione

Acheté pendant le confinement pour jouer avec ma fille, ça nous a occupé plusieurs soirées.

Missing Battery and also some M3 Hex Screws.. Am unable to test anything due to the missing items...
