DOG-12 Robot Dog
A 14-servo robot dog that walks, sits, gives a paw, dances and does a little pounce hop.
Five-Finger Robot Hand (HAND-5)
Our concept robot hand: 9 servos pull strings like tendons to bend and spread five 3D-printed fingers.
MuBot AI Desk Robot
A desk robot with round screen eyes, four servo legs and a voice: it walks, reacts to touch and tilt, and chats with AI.
LiDAR Smart Cane
One LiDAR looks ahead for poles, another looks down for potholes, and the handle vibrates before you step.
Talking Colour Detector
Hold it against a shirt, press the button, and it says the colour out loud.
Did I Lock the Door?
Away from home and not sure? Send /status and your phone tells you if the door is LOCKED, not just closed.
Talking Key Holder
Walk to the door without your keys and it reminds you. Come home and it welcomes you back.
Geyser Auto-OFF Timer
Press the button and the geyser runs for a set time, then switches itself off. Check it from your phone.
Indoor Air Quality Meter
Cooking smoke sends PM2.5 shooting up. This meter shows it live on an OLED and on your phone, and tells you to open a window.
Auto Staircase Lights
Step onto the stairs and a 12V LED strip lights up; it switches off once the stairs are empty.
Auto Pet Door
The servo arm itself is the latch: it drops to free the flap when your pet comes near, then locks it again.
Intruder Alarm with Phone Alert
Arm it from your phone. If the radar senses someone, the buzzer sounds and an INTRUDER ALERT pops up on your phone.
Car Blind-Spot Warning
A LiDAR on each mirror watches the blind spot and lights a warning LED when a bike or car is alongside.
mmWave Presence Sensor
Normal motion sensors miss a person sitting still. A 24 GHz mmWave radar sees you even when you don't move.
mmWave Home Automation
Walk in and the light and fan switch on. Sit still and they stay on. Leave and they switch off.
12 m LiDAR Radar
A LiDAR on a servo sweeps 0–180° and the ESP32 draws every reading as a dot on a live radar map.
4G + GPS Pet Tracker
The moment your pet walks out of a safe zone around home, you get an SMS with a map link.
Track 3 People with mmWave
A multi-target radar tracks up to 3 people at once and an OLED draws where each one is.
Fridge Door Alarm
Leave the fridge open for 30 seconds and it beeps until you close it, saving food and electricity.
Robot Arm Pick & Place
A 3-servo arm picks each block off one belt and places it on the other, again and again.
Smart Blind Stick
An ultrasonic sensor on the stick measures the distance ahead: the closer the obstacle, the faster it beeps.
Reverse Parking Sensor
Green, yellow and red LEDs plus faster beeps as you back up. At 20 cm: a long beep, all red, STOP.
Water Tank Auto Pump
An ultrasonic sensor on the tank lid starts the pump at LOW and stops it at FULL. No more overflow.
Touchless Soap Dispenser
Put your hand under it and the pump runs for half a second: exactly one dose, no touching.
