So much to tell you about. This kit let me create the crawler robot I was looking for. It's a toy and it's a serious investigation tool all rolled into one.Freenove delivers a versatile and functional robot that has a wide range of motion, sonic ranging and live, real-time video. It took me about 5 hours to assemble never having assembled one before.The provide a digital tutorial guide with the best illustrations I've ever seen for a tutorial guide. There are a number of YouTube videos too that take you through the step by step process, just like the guide, assembling the robot.You may have to re-read parts and/or re-watch video segments - who cares. It's all there. Every bit of the assembly.In the video, the lady assembling it has a large work area. I've included photos showing my assembly work area. Very small by comparison. Yet, I did it with little trouble. I kept a small carton near my table and moved parts from the table to the carton and back as needed. If you have a large work area, you can leave everything there.You can see it assembled on my work table. My very small work table. With it's legs folded in it takes most of the space. I built it there, in that spot.Once I ordered the kit, I watched the assembly video and noticed the lady used an electric screwdriver (for small driver bits) and I thought, yes, an electric screwdriver could make this easier, so I ordered on for about $28. I show the box in one of the pictures. Get this or another that has at minimum a few small Phillips bits. You only need one bit.The other photo shows the electric screwdriver I bought for this build. Amazon sell these and many others. I'll write a separate review of it. The point is, an electric screwdriver will reduce your build time and save your wrist.What can this robot do?1. It has adjustable height.2. Moves in any direction.3. Has a movable "head" with the sonic sensors and camera.4. Measures distance from it to an object.5. Transmits real-time video.6. Has a buzzer for simple beeping sounds.7. Has an array of programmable color LEDs.It communicates over WIFI. You'll start in your home with your own Wifi network. Out in the wild, you can establish one with your laptop, tablet or phone.There's a nice app for Windows, Mac and Linux, as well as one for IOS and Android phones/tablets.This robot is an investigation tool for me. I'm thinking of a use of legged robot and this one fits the bill nicely. It's not going to stand up to tough use, however, to test out certain ideas I have, I expect it will work nicely.Since I built it, I should be able to service it too. Need a part, I have the list. Break something, I have the list. This is one of the benefits of building it yourself.Who is this for? An adult obviously. A older kid that can be responsible and not abuse it for another. Its inappropriate for a young child to build. To operate - maybe. I'll leave that up to you to image if the person you'll buy it for fits that description.Since the programming for it is all Python, changes to the code that comes with it is completely possible. Adding new apps is easy if you know Python. If you don't, they give you a little direction to get you started. There are many free tutorials on the web for Python.You don't need to know any code at all. Build it and use it as-is. Want to experiment, it's completely possible.Customer support? They make a big deal about it. Any question - write them. I didn't need them so I don't know. I suspect they mean it. There's something about the offer, the kit and quality of the parts that leads me to believe this.
