Yahboom Jetson Nano SUB 4GB Robot Kit AI Smart Robotic Car Tank Chassis for Adults 3DOF Camera Programmable Electronics Science Project Autopilot (with Jetson Nano sub)

Difficult installation, especially the screw nuts parts. The instruction says not to roll the steering engine during hardware installation, but it always hard not to do so. Dark rivits for fixing the light stripes cannot fit the mounting hole, which has a lose end, see the pic. The installation instruction turns out to be super messy with some mistakes such as the order red-blue-black plug-in, even worse, there are steps not shown, only if you compare carefully with some individual pics, or watch the tutorial videos can you find these hidden stetps. Also the instruction for first trials are quite confusing, such as 'Method A: Plug the network cable into the Jetson NANO board.' for connecting network to Jetbot, the rest of this method is missing, I has to figure out how to do the rest by myself. This is super unfriendly for beginners. Moreover, there are some underlying conditions, such as, you cannnot use a charger Micro-USB but one Micro-USB for data transmission, or the display monitor cannot be a laptop etc. The most disappointing of this product is the power plug which is too tight for easy damage after plug in and out.
