The [Gesture Control Robot Kit with Arduino Nano + MPU6050](https://compoden.com/products/kit-gesture-controlled-robot) (₹1,570) builds a robot you steer with nothing but your hand: tilt forward and it drives forward, tilt left and it turns. The trick is a wrist-worn transmitter — an Arduino Nano reading an MPU6050 accelerometer-gyroscope — sending tilt angles over an HC-05 Bluetooth link to a second Nano on a 2WD chassis. **This is an Intermediate kit with a realistic 5–6 hour build, and it is the most "magic-feeling" project in our range: sensor fusion, wireless communication and motor control combined into something you demo with a flick of the wrist.** Two complete Arduino systems in one box means you are genuinely building a distributed system — transmitter and receiver — which is exactly why it teaches more than a single-board robot.

## What's in the box
Two Arduino Nanos, an MPU6050 accelerometer-gyroscope, two HC-05 Bluetooth modules, an L298N motor driver, two TT gear motors, a 2WD chassis, two 18650 cells with holder, filtering resistors (4.7kΩ and 10kΩ) and 100nF capacitors, and 30 male-male jumper wires. Two honest notes from the product page: the Nanos and HC-05s ship as bare modules, so you will solder header pins onto them, and a breadboard for the sensor-filtering experiments is not included.

## What you'll learn

- **I2C sensor reading** — pulling raw accelerometer and gyroscope data off the MPU6050 and converting it into stable tilt angles, your first taste of sensor fusion.

- **Bluetooth pairing at the protocol level** — configuring two HC-05 modules into a master–slave pair using AT commands, not an app: baud rates, passwords, automatic reconnection.

- **Two-node system design** — programming a transmitter and a receiver that exchange real-time data packets, with all the framing and dropout questions that implies.

- **Motor mapping** — translating gesture direction into L298N commands and PWM speeds so tilt intensity feels proportional.

## The build, honestly
Budget the full 5–6 hours, and know where they go. The soldering is first: header pins onto two Nanos and two HC-05s. It is beginner-grade soldering, but if you have never held an iron, practice on the spare headers before the real boards. The step that trips most people up, though, is the HC-05 pairing session — putting one module into AT-command mode, setting master/slave roles and matching passwords. It is fiddly the first time, well-documented, and once done the pair reconnects automatically on every power-up. The MPU6050 also rewards patience: raw accelerometer data is jittery, and the difference between a twitchy robot and a smooth one is the angle filtering the kit's resistors and code walk you through. When it finally drives from your wrist, all of it feels worth it.

## Who it's for — and who should skip it
Built for CBSE Class 11–12 investigatory projects, engineering undergraduates exploring wireless embedded systems, and hackathon teams — the wrist-transmitter design reads as low-cost wearable and assistive tech, which is why it scores well at expos. If you have already built one wheeled robot and want a genuine step up in systems thinking, this is that step.
Skip it if this would be your first robot ever — the two-board architecture and soldering make failures harder to isolate. Start with our Obstacle Avoiding Robot Kit or the Maze Solving Robot Kit, both single-board beginner builds, and come back. Conversely, if AT commands and I2C hold no mystery for you, the Ball Balancer PID Kit or the Hexapod will stretch you further.

## FAQ

### Does it require soldering?
Yes, some: male header pins must be soldered onto the Nano boards and HC-05 modules. All other connections use jumper wires. A breadboard (not included) is useful for the sensor-filtering experiments.

### How do the two Bluetooth modules pair?
Via a short AT-command session: one module is set as master, the other as slave, with matching baud rate and password. After that they pair automatically at every power-up.

### Is this usable for college competitions?
Yes — the product page notes undergraduate teams have used this design in events like Smart India Hackathon and department expos, where the wearable-controller angle stands out.
The kit arrives pre-loaded in Soldr, our AI build assistant, which generates the wiring for both boards, the transmitter and receiver firmware, and step-by-step troubleshooting — including that first HC-05 pairing.
