Task and control
Form
Form	Humanoid	Humanoid
Use
Use	Companion, Education	Education, Research
User programming

Phone app
Phone app	Yes	Yes
Intended use
Intended use	–	Humanoid movement demonstrations and robotics research; the EDU configuration supports secondary development. Demonstrated dexterous manipulation does not establish standard out-of-box household work.
Movement
Movement	Bipedal robot and tracked tank; maker lists 5 cm/s and 10 cm/s respectively.	Standard G1 has 23 joint degrees of freedom, including six per leg, five per arm and one waist joint. EDU has 23–43 depending on optional waist, wrist and dexterous-hand joints. Standard joint movement ranges include knee 0–165° and waist rotation ±155°.
Autonomy
Autonomy	–	The maker describes imitation and reinforcement learning and its UnifoLM model. It explicitly warns that some example functions remain in development/testing; those demonstrations do not prove autonomous general-purpose work in the purchased base configuration.
User programming
User programming	–	Standard G1 does not support secondary development; EDU supports it. EDU can add optional compute modules such as Orin. The store also offers a G1 Pro variant, but its exact distinct specification is not published in the G1/EDU table used here; do not assume that Pro is EDU.
Remote control
Remote control	Voice and app control.	Handheld controller included; maker G1 app available.
Regional availability
Regional availability	Standard SKU WZTG1F-SE orderable from UK store on 3 October 2026; purchase area states shipment in 3–5 days. Limited-anniversary edition is separate.	The official global store accepts orders for G1 and G1 Pro; it gives delivery details upon request rather than a guaranteed immediate delivery date. EDU requires contact with sales. Freight and local customs/import clearance apply. Checked October 2026.
Release details
Release details	Exact first-sale date not established; store update and preorder dates are not retail dates.	Unitree confirms the initial announcement on 13 May 2024 and a mass-production version on 19 August 2024. Neither announcement establishes the first retail delivery date, so that date is left unpublished. Current specifications use the maker's 1,320 mm height rather than its earlier 1,270 mm event wording.

Processing
Processing	–	Eight-core high-performance CPU. EDU optionally accepts additional computing modules including Orin; no exact standard CPU model is specified.
Sensors
Sensors	Six-axis IMU and chest/back touch zones.	Depth camera and 3D LiDAR; dual joint encoders.
Camera
Camera	–	Depth camera is listed across G1 and G1 EDU. No camera image-resolution figure is published in the exact table used.
Audio
Audio	More than 270 recorded voice lines.	Four-microphone array and 5 W speaker.
Display
Display	112 LEDs.	–
Actuators
Actuators	36 servos; this is not assumed to mean 36 independent degrees of freedom.	Permanent-magnet synchronous motors, industrial crossed-roller bearings and local air cooling. Maximum largest-joint knee torque 90 N·m for G1 or 120 N·m for EDU; not every motor has that torque.
Payload
Payload	–	Arm maximum load approximately 2 kg for G1 or 3 kg for EDU, depending strongly on arm-extension posture. This is not a whole-body carrying payload.
Connections
Connections	Bluetooth 5.0 BLE; USB-C charging.	Wi-Fi 6 and Bluetooth 5.2.
Size and weight
Size and weight	Standard-edition maker table gives robot 6.6 × 13.9 × 20.6 inches and tank 17.3 × 9.1 × 6.0 inches without axis labels; net weight 8.4 lb. Rounded imperial values retained.	Standing height × width × thickness 1,320 × 450 × 200 mm; folded 690 × 450 × 300 mm. Standard weight about 35 kg with battery; EDU is about 35 kg or more depending on equipment. Current maker photographs can show optional dexterous hands, which are not supplied with the standard G1.
Accessories
Accessories	–	EDU optionally adds two waist joints, two wrist joints per hand and force-controlled three-finger Dex3-1 hands; each hand has seven active finger degrees of freedom. Tactile arrays are optional. Photo captions identify shown optional equipment.
