HCR - A Mobile Robot Platform Kit with Omni Wheels

HCR (Home Care Robot) with Omni Wheels is a full‑metal open‑source mobile robotics platform built for advanced robotics research, service robot prototyping, and experimental automation projects. The omni‑directional research robot chassis combines a layered mechanical structure with precision motion control, enabling flexible integration of sensors, computing boards, and AI vision hardware. Designed as a modular robotics development base, the platform supports widely used controllers including "Arduino", "Raspberry Pi", and "LattePanda". This omni‑wheel robot base provides a reliable foundation for building autonomous navigation systems, mobile service robots, and intelligent research prototypes.

Note: The platform is delivered as an assembly kit requiring mechanical installation. The kit includes structural components such as metal plates, screw sets, switches, and sockets. Circuit diagrams are provided in the installation manual, allowing additional electronic modules to be integrated according to project requirements.

Omni‑Directional Mobility with Encoder Feedback

The robotics development platform integrates three high‑torque omni wheels paired with encoder‑equipped DC motors, enabling smooth holonomic movement across multiple directions without changing chassis orientation. This omnidirectional drivetrain supports precise translational motion, rotation in place, and complex navigation maneuvers required in indoor robotics experiments. Accurate encoder feedback further enables closed‑loop control, trajectory planning, and advanced robotics algorithms commonly used in autonomous mobile robot research.

Expandable Three‑Layer Mechanical Architecture

The multi‑tier metal frame adopts a three‑layer modular structure designed for flexible hardware expansion. Each layer provides mounting slots for installing distance sensors, servos, cameras, and additional robotics peripherals. Dedicated mounting positions support ultrasonic sensors, infrared distance sensors, and robotic vision equipment such as Kinect cameras. This expandable robotic chassis layout allows engineers and researchers to build complex perception and interaction systems while maintaining a compact and organized hardware configuration.

Broad Compatibility with Popular Development Platforms

The open architecture mobile robot base supports integration with a wide range of embedded computing and control boards. Compatibility with popular development ecosystems such as "Arduino", "Raspberry Pi", and "LattePanda" enables flexible software development and hardware expansion. Through these controllers, the research robot platform can implement functions including line tracking, obstacle avoidance, visual interaction, and autonomous navigation, making the system suitable for both experimental robotics studies and advanced prototype development.

Recommended Optional Expansion Devices

Typical configurations for advanced robotics experiments may include motor drivers such as DC Motor Driver 2×15A - Lite, power modules like 72W DC-DC Converter 12V@6A, sensing units including Sharp GP2Y0A21 Distance Sensor (10‑80cm), Gravity:Digital Infrared Distance Sensor (10cm), and URM04 v2.0 Ultrasonic Sensor. Control solutions may incorporate Bluno Mega 2560 - An Arduino Mega 2560 with Bluetooth 4.0, Mega Sensor Shield V2.4, and communication tools such as Multi USB/RS232/RS485/TTL Converter.

This omni‑wheel robotics chassis is suitable for autonomous navigation research, indoor service robot development, academic robotics experiments, and advanced STEM Education robotics projects. The modular robot base provides a robust mechanical and electronic framework for building mobile robotic systems capable of sensing, interaction, and intelligent movement.
