Mechanical 4WD Robot Arm Smart Car Kit - STEM/Graphical Programming Robot Car Compatible with Arduino IDE - Tutorial Included

Grandson loved this !

I bought for my step daughter who wants to be a electrical engineering like her stepfather. It was a great starting point for her to understand the building process and coding.

Good toy for adults with patience and time. Mine broke.

Very low quality. Broke during assembly. Returning.

One plastic part went broken when I assembled robo. I think that I do it from alumine material because plastic is so difficult place in a car. Of course you can send me other part!

Be carefull , large plates ( top and accessories ) are not painted in black and are row You have to buy a spray black paint for finish the look of the product I claimed AMAZON to get a discount , rather to try a replacement because I not sure to get a full painted robot

Instructions could be better but I managed to assemble it and tested all the programs except the Bluetooth part because the pin out doesn't match between the hardware and the instructions manual. I didn't want to risk destroying the electronic so I didn't connect the Bluetooth module. Everything else works fine. You will need to buy 2 18650 batteries and a button cell for the infrared remote controller. To have the robot follow the line, you must use the included electric tape.

Doesn't come with batteries or charger, which was not clear from the product description. Some parts of the arm are very prone to breaking. Assembly requires many screws of many different sizes, which makes it difficult. They need to improve the quality of the design for ease of assembly, and the quality of their parts for strength. Also, the instructions are not well translated into English, making some parts unclear.

México, Septiembre 2022 Es un buen producto para aprender o reforzar tus conocimientos en programación con ARDUINO, te ayuda a mejorar tu coordinación ojo mano y mejorar tus habilidades de construcción. Me gusta que tiene varios modos de trabajo. Incluye todo lo necesario para armar, tiene todas las lecciones bien explicadas para que las sigas paso a paso y no te pierdas en el proceso. NO TRAE baterías, te recomiendo usar un porta-pilas para 4 pilas AA con broche o una pila de 9 volts con broche, o cualquier otro conjunto de pilas que no pase de 9 volts, pueden ser las 18650 o cualquier otra. Llegó en buenas condiciones y antes de lo esperado. En cuanto lo arme subiré fotos del armado y un video del funcionamiento.

Falta una de las piezas grandes de madera, solo llegó una de ellas

Instalación placa fotodiodo sobre microcontrolador, servos 360°, detector colores, conexión Bluetooth a celular
