Unitree R1 Two-hand remote control

The Unitree R1 Two-Hand Remote Control (often referenced as the R3-1 in technical documentation) is a high-performance, ergonomic wireless controller specifically engineered for the Unitree R1 humanoid and the broader Unitree robotics ecosystem.

Designed for both precision and ease of use, it allows operators to perform complex tasks, from basic bipedal locomotion to dexterous hand manipulation, through an intuitive dual-stick interface.

Key Features

Ergonomic Two-Hand Grip: Specifically designed to reduce fatigue during extended research or development sessions. The layout mirrors professional gaming controllers for a shallow learning curve.
High-Precision Hall Joysticks: Dual rockers provide ultra-fine resolution for 3-axis posture and 3-axis position control, essential for balancing and complex humanoid movements.
Dedicated Function Keys: Features programmable buttons ( $F1$ – $F3$ ) and shoulder triggers ( $L1/L2$ , $R1/R2$ ) to trigger pre-set routines like “Get Up,” “Stand,” or “Dance.”
Dual-Mode Connectivity: Combines a proprietary high-speed data transmission module for low-latency control with Bluetooth for versatile pairing options.
Real-Time Feedback: Equipped with a multi-LED array to monitor battery status, Bluetooth signal strength, and data link stability at a glance.

Precision Control for Humanoid Tasks

Unlike standard quadruped controllers, the R1 remote is optimized for the 24–40 Degrees of Freedom (DOF) found in the R1 humanoid. It allows for:

Dynamic Locomotion: Controlling walking speed, direction, and height in real-time.
Dexterous Manipulation: When paired with the R1 EDU, the controller can be used to manually guide the robot’s three-fingered or five-fingered hands for grasping tasks.
Emergency Interventions: Instant “damping” or “stop” commands to prevent damage during experimental falls.
