Intel Realsense D435i for Unitree
The inertial measurement unit (IMU) detects movements and rotations in six degrees of freedom (6DoF). It integrates various sensors and gyroscopes to measure both rotation and movement across three axes, including pitch, yaw, and roll. IMUs are commonly used in applications such as gaming, pointing devices, and image stabilization.

Applications
project1.Combined Solution for Development & Productization
The Intel® RealSense™ D435i seamlessly integrates a 6-axis IMU into its advanced stereo depth sensor, combining Intel’s vision processing module and high-performance processor into an ultra-compact design. This self-contained system delivers real-time motion-aware depth data, enabling autonomous robots and AR/VR devices to track their own position and orientation through customizable software solutions.

project2.Ideal for cameras in motion
The D435i offers an ideal solution for applications like robotic navigation and object recognition due to its combination of a wide field of view and global shutter sensor. This wider field of view enables a single camera to cover more area, reducing "blind spots." Additionally, the global shutter sensors enhance low-light sensitivity, allowing robots to effectively navigate in dark spaces.

project3.Complete Suite for Simple Integration
The D435i depth camera is a member of the Intel® RealSense™ D400 series. This series combines Intel’s latest depth-sensing hardware and software into products that are easy to integrate. Ideal for developers, makers, and innovators aiming to incorporate depth sensing into their devices, the Intel® RealSense™ D400 series cameras provide seamless out-of-the-box integration, paving the way for a new generation of intelligent vision-equipped solutions.

Why choose Intel RealSense D435i for Unitree?
Adding an IMU to your application enhances depth awareness in dynamic situations where the camera is in motion. This capability facilitates basic SLAM and tracking applications, leading to better point-cloud alignment. It also improves environmental awareness for robotics and drones.
By utilizing the IMU, registration and calibration become easier for handheld scanning applications and are crucial for virtual and augmented reality use cases. When paired with the D435i, the Intel RealSense SDK 2.0 provides IMU data that is timestamped, ensuring precise alignment with high-quality depth data.

Important Notice:
- Inventory Status: Please check the inventory status on the product page. Our system displays real-time stock for our Munich and Long Beach warehouses. If an item is out of stock in these locations, it will be marked as "Pre-order". You can still place an order for these items.
- Pre-order Fulfillment: For "Pre-order" items, we arrange the most efficient logistics solution to ensure you receive your goods as quickly as possible. Your package may be shipped directly from our Shenzhen warehouse. Alternatively, as part of our standard restocking process, we may transport the goods to our Munich or Long Beach warehouse first (typically taking 5-10 business days) before dispatching them to you.
- Split Shipments: If your order contains both in-stock and Pre-order items, we will prioritize shipping the in-stock items from the local warehouse immediately. The remaining Pre-order items will be sent to you in a separate shipment once they are ready.
