Its appearance design is unique, and the aluminum alloy material makes it feel very solid. However, it was very difficult to assemble the chassis. I repeatedly checked the instructions, installed the video, and disassembled it countless times before I completed the assembly. I have to say that if you have no experience in structural construction, it will be very difficult for you.
I encountered some minor problems during use, but the email response was very fast and helped me solve the problem.

The packaging of the product is OK, with basic protective measures, but the protection is slightly insufficient. The outer white packaging box was slightly deformed during transportation, but the product itself was not damaged. The delivery speed is medium, not particularly fast. There is room for improvement in packaging and transportation.

I am testing it according to the instruction manual, hope everything goes well.

The packaging and accessories are very neat.

The assembly is very simple, the chassis looks complicated, but it has been assembled.
The instructions and online tutorials are very detailed (but the English level is a bit poor), and you can complete it smoothly by following the steps.

The combination of the robotic arm and the Tank car is very interesting, and many intelligent functions can be realized through programming, such as obstacle avoidance, path planning, etc.

It has a sturdy chassis material, exquisite design, and easy installation.
I am using it to implement my automatic navigation project and the results are very good. The track system performs well on various terrains and moves very smoothly. I am very satisfied with this purchase and recommend it.

The quality of the parts is very good, the chassis has been assembled, which saves us a lot of time, and we quickly completed all the steps according to the imperfect instructions.
The design of the robot arm is very sophisticated, but it is too short to be extended.
The crawler design allows the car to easily cope with various complex terrains, increasing the diversity of use.

Using Raspberry Pi as the control center, through programming, we realized various functions of the car, including remote control, path planning and automatic obstacle avoidance. However, during use, we found that sometimes the grasping accuracy of the robot arm is not very high, and manual debugging is required. In addition, for beginners, the initial setup and programming may be a bit complicated, requiring patience and a certain amount of learning time.

The battery life of the car also needs to be improved, and it needs to be fully charged in advance before each long-term use.
