Overview
The Robosen Interstellar Scout K1 Pro is a programmable bipedal humanoid robot from Robosen Robotics, the Shenzhen-based maker also known for its officially licensed Transformers and Disney-Pixar robots. It walks freely on two legs using high-precision flexible servo joints, simulating a human-like gait without external supports or tethers.
The robot is built from aerospace-grade materials with an aluminum-alloy frame and a gunmetal-gray matte finish, giving it a durable yet lightweight body that is easy to carry. Robosen markets the K1 Pro as a next-generation family entertainment and STEM education robot, aimed at children, hobbyists, and creators alike.
The K1 Pro emphasizes accessibility through multiple control methods: voice commands for screen-free interaction, a companion app, and both block-based and manual programming so users can author and refine their own action sequences and movements.
Key Features
- Free-walking bipedal locomotion driven by high-precision flexible servo joints that simulate a human-like gait
- Voice control with a large library of pre-installed commands for hands-free, screen-free interaction
- Dual programming modes: visual block-based programming and manual control for hands-on creativity
- Aerospace-grade aluminum-alloy construction with a gunmetal-gray matte finish for a lightweight, portable build
- Companion-app connectivity with pre-installed actions and dance routines

Record changelog
- Height: 95 cm → 349 mm (13.7 in) · Jul 8, 2026
tranche-3 verification (corrected): Official dimensions: 6.9×3.9×13.7 in (176×99×349 mm) — matches core height_mm=349. 95 cm is the Booster K1's height — contamination; spec row contradicts core.
- Weight: 19.5 kg → 0.94 kg (33.16 oz) · Jul 8, 2026
tranche-3 verification (corrected): Official: 33.16 oz (0.94 kg) — matches core weight_kg=0.94. 19.5 kg is the Booster K1's weight — contamination; spec row contradicts the record's own core field.
- Degrees of Freedom: 22 → 17 (servo motors: head ×1, hands 3×2, legs 5×2) · Jul 8, 2026
tranche-3 verification (corrected): Official: '17 servo motors (Head ×1/Hands 3×2/Legs 5×2)'. 22 is the Booster K1's DoF count — contamination.
- Sensors: 3D depth camera, 9-axis IMU, microphone array → Onboard voice recognition (82 voice command words); no depth camera or IMU listed by Robosen · Jul 8, 2026
tranche-3 verification (corrected): Current sensor list is the Booster K1's (stereo depth camera / 9-axis IMU / mic array) — contamination. Robosen's official spec sheet lists 17 servos, 2000 mAh batt
- SDK Support: Yes → No (app-based block/manual programming only; no public developer SDK) · Jul 8, 2026
tranche-3 verification (corrected): Robosen offers programming through its mobile app (block-based and manual modes), not a developer SDK. Contamination from the Booster K1 record.
- ROS Compatible: Yes → No · Jul 8, 2026
tranche-3 verification (corrected): Consumer STEM toy controlled via BLE Bluetooth 4.2 and the Robosen app (block-based/manual programming, voice commands). Official specs list no ROS support anywhere
- Battery Life: 55 minutes → 55 minutes (≈0.92 hours) · Jul 8, 2026
tranche-3 verification (corrected): Official: 'approximately 55 minutes' play time (2000 mAh pack). Value string is right; numeric_value=55 against canonical_unit hours is a minutes→hours normalizatio
