This kit consists of LEGO-style bricks and a Bluetooth controller box that requires 3 AA batteries. The controller box contains 2 motors, an infrared sensor, and a color sensor. The best feature of this kit is its compatibility with other LEGO bricks, allowing limitless possibilities for building.

I ordered this set for my 9-year-old child. He had an absolute blast constructing a batmobile-style RC car, following the instructions provided in the booklet included in the box. He was able to program a simple code to make it move a certain distance, turn back, and return to its original position. In addition to the RC car, he also built the crane. However, he struggled to build it entirely on his own and required some assistance. The instructions were not very clear. For example, the instructions for the crane indicated to simply loop the cord in one pulley, which was confusing for a child as a looped cord would not hold. I had to instruct him to tie a knot instead.

Moreover, the instructions and coding tutorials do not explain how to use the infrared sensor or the color sensor properly. The code contains conditional statements like "If Infrared sensor(1-7) == x", where x can be any number between 1 to 7. However, the instructions do not clarify what each number from 1 to 7 represents. Similarly, for the color sensor, the conditional statement is "if color sensor(1-3)", but there is no explanation in the introductory course on the code about which color corresponds to each number or even that each number represents a color. Furthermore, regarding the infrared sensor, I believe the number represents how many times you block the sensor with your waving hand in quick succession. However, I will need to verify this further to be certain.

The instructions for the crane were also in a confusing order, making it more challenging to build. Parts that were assembled earlier were not reinforced, resulting in potential breakages when returning to reinforce those sections later. This kit would have been perfect if the instructions were clearer and explanations were provided more thoroughly. Additionally, the sensors were connected to the controller module with fixed wires, which tended to hang and stretch out while my child was building the projects. I am doubtful about how long these wires can hold up under frequent use. It would have been much better if these wires were modular, allowing for easier management and reducing the risk of wear and tear.

I am eager for my child to build the other 8 models that this kit offers, along with many more creations by combining it with our LEGO set. Overall, I would definitely recommend this kit, with the hope that they refine the instructions and provide better explanations for future users.
