Robot Brief

EVE is a wheeled, self-balancing humanoid robot developed by 1X Technologies (formerly Halodi Robotics), first deployed in 2020. It was designed to serve as a commercial workhorse for industrial and institutional environments, providing a real-world platform to develop and stress-test 1X's proprietary actuation, AI, and perception technologies at scale. Standing 1,830 mm tall with a humanoid upper body and a multi-terrain wheeled base, EVE is built to operate autonomously in human-centric spaces without requiring facility modifications, performing manipulation, navigation, and logistics tasks alongside human workers.

Use Cases

Autonomous Facility Navigation:
Navigates independently through complex indoor environments including corridors, doorways, and elevators, adapting to dynamic obstacles in real time.
Object Manipulation and Logistics:
Carries, moves, and handles objects ranging from heavy boxes to delicate items, supporting material flow and logistics tasks in warehouses and industrial facilities.
Access and Infrastructure Interaction:
Opens doors, operates elevator controls, and interacts with physical infrastructure designed for human use, enabling operation across multi-floor facilities.
AI-Driven Task Learning:
Learns new tasks through embodied AI by observing human operators, reducing the need for explicit programming for each new workflow.
Remote-Supervised Operation:
Supports shared autonomy where human operators can remotely take control of complex or unfamiliar tasks via a remote operation system.
Security and Surveillance Patrols:
Conducts facility patrols, monitors access points, and provides situational awareness for security operations.

Industries

Logistics and Warehousing:
Automates item handling, order picking, and internal transport in warehouse and distribution centre environments.
Healthcare:
Delivers medications, supplies, and equipment within hospital corridors, reducing staff workload in routine transport tasks.
Manufacturing:
Supports material handling, inspection assistance, and floor-level logistics in manufacturing facilities.
Security and Facilities Management:
Patrols buildings autonomously, monitors access, and provides a mobile presence for security teams.
Corporate and Office Environments:
Handles document delivery, equipment transport, and general floor-level logistics in commercial office settings.

Intro

EVE is a wheeled humanoid robot standing 1,830 mm tall and weighing 83 kg. Its upper body is humanoid in proportion, constructed from a combination of plastic, aluminium, and fabric, while its lower assembly uses a multi-terrain wheeled base that provides self-balancing locomotion at speeds up to 4 m/s (approximately 14.4 km/h). The arms are fitted with gripper-style hands designed for both precision manipulation and load-bearing tasks, supporting a maximum payload of 15 kg. EVE's 25 degrees of freedom are distributed as 7 DoF per arm, 6 DoF in the wheeled leg assembly, and 1 DoF each for the neck, hands, and wheel actuation. All joints are driven by 1X's proprietary Revo1 quasi direct-drive actuators, which combine a high torque-density brushless DC motor with a low gear-ratio cable-driven transmission, producing near-zero backlash, extremely low friction, and full-torque backdrivability for safe human co-working.

EVE's perception system comprises three high-resolution HDR cameras covering panoramic forward and rear fields of view, enabling computer vision-based obstacle detection, object recognition, and environment mapping. Onboard compute consists of an Intel i7 processor for real-time control tasks and an NVIDIA Jetson Xavier module for AI inference. The AI stack is driven by a customised GPT-4-based neural engine that processes natural language commands and uses a single vision-based neural network running at 10 Hz to coordinate driving, arm control, and grip functions simultaneously. Task learning occurs through embodied AI workflows developed in the 1X Studio, where the robot observes human demonstrations and iteratively refines task execution policies. A 1.05 kWh lithium-ion battery provides up to 4 hours (240 minutes) of continuous operation.

EVE runs on a custom Linux-based operating system and supports ROS2, OpenCV, and open-source robotics frameworks, with application development supported in Python, C++, and Java. As of 2025, EVE has been superseded by NEO as 1X Technologies' primary product focus, and the platform is no longer actively marketed to new customers. Its operational deployments remain in service at existing customer sites.

Capabilities

Autonomous Indoor Navigation:
Navigates complex indoor environments, including corridors, doorways, and elevators, using vision-based perception and SLAM without pre-mapping requirements.
Dexterous Manipulation:
Handles objects of varying size, weight, and fragility using gripper arms capable of precision grip control and load-bearing up to 15 kg.
Embodied AI Task Learning:
Learns new tasks by observing human operators via the 1X Studio workflow, enabling skill acquisition without explicit reprogramming.
Natural Language Command Execution:
Interprets and chains complex multi-step tasks from voice commands using a GPT-4-based language and reasoning engine.
Shared Autonomy and Remote Operation:
Supports remote human control for complex or novel situations, enabling a hybrid autonomy model appropriate for safety-critical environments.
Multi-Robot Fleet Coordination:
Operates collaboratively alongside other EVE units on large-scale or sequential tasks within a shared facility.
