Key Engineering Highlights
- Wraps its flexible TPU arms around backpack straps, tote handles, or desk lamps—weighing just 155g to pioneer the wearable 'social icebreaker' companion category
- Fuses an infrared proximity sensor, sound-direction detector, capacitive head sensor, and 6-axis IMU to peek curiously at nearby people and shyly bury its face when startled or tapped
- Operates 100% offline with zero cameras, zero microphones recording to the cloud, and 8 hours of battery life per USB-C charge
