UNO R3 Conqueror Robot Tank Kit

Features 5

  • BUILD A METAL TRACKED ROBOT: Assemble the stainless-steel chassis, suspension, tracks, sensors and UNO R3 control system into a working robot; ideal for home STEM projects, homeschool lessons, coding clubs and classroom builds
  • EXPLORE FIVE INTERACTIVE MODES: Switch between FPV driving, IR remote control, obstacle avoidance, line tracking and auto follow; create patrol routes, black-line courses, maze challenges and navigation experiments
  • DRIVE FROM THE ROBOTS VIEW: The camera and ESP32-WROVER Wi-Fi module stream live FPV video to a compatible phone, while the adjustable servo-mounted camera lets you change the viewing angle during driving and inspection
  • START WITH BLOCK CODING, ADVANCE TO ARDUINO IDE: Use the ElegooKit app for visual programming, then modify motor speed, sensor thresholds, servo movement and navigation logic in Arduino IDE as coding skills grow

Description

At ELEGOO, we make STEM learning more approachable through hands-on electronics, coding, and robotics kits. Each kit includes the boards, sensors, wires, modules, and components learners need to build real projects and explore programming, circuits, IoT, and robotics with confidence. We are committed to making STEM education easier to start, more enjoyable to practice, and more accessible to the next generation of creators, engineers, and makers. Chris, the founder of ELEGOO, found out that most enterprises in the STEM industry focused on the hardware of open-source electronics and did not have tools to create a complete product by combining electronic hardware and structural shells. We have excellent R&D team, constantly upgrading and improving products, and after-sales service team for quick support. 100% compatible with Arduino, ELEGOO's kits are best-practice for beginners who have no appropriate technical tools to learn about electronics. Specifications: Start with visual block-based programming in the ElegooKit App to control lights, sensors and movement, then progress to text-based coding with Arduino IDE. Progress from introductory visual programming to more advanced text-based coding projects Stream live video over Wi-Fi to a compatible phone and control the robot from a first-person view. The two-axis camera gimbal lets you adjust the viewing direction while driving In obstacle-avoidance mode, the ultrasonic sensor measures the distance to objects ahead so the robot can change direction before a collision. Keep your car away from collision and enjoy the fun. The infrared line-tracking module detects a dark line against a lighter surface and guides the robot along the path. Use a clear, high-contrast track for more reliable line following. PS: This function works when the line is black.

Great kit that is easy to put together and results in a really nice, usable vehicle.
Fun kit. This kit is great because it is intricate enough to feel like you are actually building something while being easy enough for a novice. For someone new to robots this provides a good basis for what various do and how they work. There is no soldering, and in the end you have a nice RC vehicle with FPV capability that is fun to use. ... show more

Great! Well put together!
The instructions are amazing, and through. And if you download the app before building it, the instructions are even better on the app. If you can put Legos together you can do this. Operates great out of the box. No programs to upload or flash. It just works with the remote and the app. Lots of fun with the kids. First upgrade will be lights. It is hard to see in FPV in a dark room. The line following circuit board gets caught on everything. I say if your not using it don't install it. Without it, it will climb mountains. I did notice some screws loose after hours of play. So I recommend getting some blue LockTite. Great Kit! ... show more

Great project
Awesome kit, my 9-yr loves it.

Overall fun project
Wanted to get into learning to build servo robots from parts but needed a starting point. This tank kit seemed perfect. The kit comes well packaged and very well organized. All of the parts are labeled and photo instructions fairly easy to follow. The frame is very sturdy, which is great, but that also causes an issue with connectivity. The primary control feature is IR (infra-red, like the TV remote). Unfortunately, the straight-line connection is blocked by the metal frame except from directly behind and low as the frame is not enclosed at the back. That means if you are standing directly above it or turn it 90º or more you lose control until you change where you are standing. The IR sensor is soldered in, so it cannot be moved on top of the tank unless you use the alternate assembly instructions which places the entire computer board on top of the frame--which is ugly and clunky looking. The secondary form of remote control is supposed to be via wi-fi using the Elegoo app; however, I have not been able to get most of the features to work properly. The app shows it is connected and I am able to see the camera feed; however, the controls to move the direction of the camera are not working. Even more importantly, the tank does not respond to any of the app controls or settings via wi-fi either. The troubleshooting part of the Elegoo site didn't really offer much help apart from a YouTube tutorial video. It drives a little crooked out of the box. The tutorial only recommends making sure it is flat so the sensor can calibrate when you turn it on. That unfortunately didn't help. Overall, I think this is a really cool kit with lots of features. I had hoped they would work perfectly straight out of the box. Instead, it looks like I will need to spend some extra time making minor adjustments. Still a pretty good kit to start with. ... show more

Great project
Bought this for my 13 year old son and it took him about 2hrs to assemble. He loves it. He hasn't played with computer coding with it yet. Highly recommended project for kids with mechanical ability
