DJIRoboMaster S1 - Educational Robot STEM Programmable Science Learning Mini Car Remote Control Intelligent AI Scratch Python Coding 5MP 1/4" CMOS Camera

This was a gift for my eight year old grandson. He mastered how to control it in a matter of an hour or two. He plays with it every single day and will not tire of it anytime soon. All of his friends think it’s the coolest thing ever! It was a fantastic choice for his Christmas gift.

Purchase 3 untis and one was empty box and was returned and refunded 2 were new. The robot is well build and it worth the price

while the robot is great or was great because it's already been 5 years since the first year of production there hasn't been a any upgrades nor updates coming from the manufacturer .they completely stopped the project that couldvebeen a very popular.they could upgrade the camera, implement proximity sensors, make it with collision avoidance, program many smart features and add speach recognition and on and on and...but they dumped it.5 years later it's now way overpriced for what it can't do.other than that yes it's tough built, fast, responsive.but... lacks innovations.

The button to remove the battery will get stuck and you will not be able to use it and the gimbal/head will randomly start drifting up and you will not be able to look down and it is impossible to assembleIt took me 6 hours to assemble just please do not buy this thing its also overpriced for such garbage

Solid build good quality robot and this is absolutely not just a toy. The app and software also very easy to use. Absolutely a great STEM learning tool.

Don't get me wrong, it has some nice features with the camera, nice gimbal, nice IR blaster and the interface is neat. As an RC Toy it is pretty dang nifty, but as a STEM learning aid you should either look elsewhere for the price range or buy something cheaper that does more.Now, the issues: * The bead cannon doesn't really work right on either one, it spits them out. (both bots) * The sensors suck. They advertise 7(!) IR wide sensors and 2 IR narrow sensors. Yeah, you can't address them and all they are is turret mounted hit sensors (on/off, not R/L/F/B or anything, just "you've been hit".) There is no IR ranging, no you've been hit from behind. * The "armor" sensors are just mics that are supposed to hear the beads hitting it, but the bead guns don't work well and you have to hit the "armor" plate.Basically for programming you are get to make it move around or use their inbuilt number recognition and shoot number targets. You can't program combat robots to react to each other, you can't have it follow a wall, you can't find/range another robot.

If you are looking at further development with the python SDK, please stay away.Please see details at dji-sdk/RoboMaster-SDK on github issue #10.

The robomaster is made in China just from knowing that you must never buy it, It costs too much yet contains very little features if you are using mobile and is made from pretty much the weakest plastic and the most crucial part is pretty much covered with the weakest plastic. A fall from 1 feet of height is the death of your robomaster like mine it loses it connectivity and cannot connected to your pc or mobile depending on the side it fell on.The building part is fun but if you are not lucky you could get a product that doesn't work at all even if you built it correctly.

The media could not be loaded. Let's me start this review by explaining why I brought this.I wanted to have fun driving a RC TOY with advanced controls like precise driving, drifting, shooting, racing and capturing.I was able to achieve all of this without any hassles.You can drive with max speed of 3.5 meters / secYou can drift sideways with those mecanum wheels,You can shoot gel beads and infra lasers with the build in blaster.You can record great videos with the built-in HD camera at 30 FPS.DJI provides an app for andorid, ipad/iphone and windows desktop to control this device.you connect through the device built in WIFI or use your router.Now lets come to the core features of this device .Assembling - The products comes disassembled into multiple parts. See attached screenshots. It took me 4 hours to assemble this device. To be frank it was fun building this device.Programming - This device supports scratch and python coding. Unfortunately the app only supports scratch coding. For python you need to install a SDK and need good knowledge of coding.ROBOMASTER championship - you can program this to fight in some cool robotic competitions. Check out Robomaster tournaments.Advanced attachments - This comes with extra accessories you need to by separately. Check the ROBOMASTER EP1Limited capabilitiesWell I got all the pros of this device right, now for the actual issues.I would not mind paying around 45-50k for these feature if they worked perfectly, unfortunately this feels like this products needs more work. Read on for more details.-While controlling this device from Keyboard in windows feels precise, mobile controls lack precision. you will tend to crash frequently while controlling from the touch based interface.You might need to spend another 5000 Rs on their controller accessory sold separately. Good luck finding them in our country.-Camera quality is average. Donot expect DJI OSMO or GOPRO quality . it's good for tracking purposes only.-You can only connect to one device at a time. Switching device, you need to go through the connection manager every time.-Programming bugs- While most of the code executes flawlessly donot expect precision. For example, I never got it to rotate a full 180 degree while using the rotational speed API.-Battery- 35 mins on the built-in 2500mah battery. This should not be a surprise considering DJI drones barely manage 15-20 mins.Accessories availability : It's difficult to find accessorie for this product at least in India. You would want to buy a spare battery, the additional controller, gelbeads and the EP1 and side guards.

One of the important part is available in the box. So I cannot assemble the robo master without that.I was really disappointed. The part E1 * 4 pcs needed to assemble the chassis along with the respective 4 motors. Then I decided to send it back.
