1
Procurement & Preparation
- Inventory and verify all BOM items including NVIDIA Jetson Orin Nano, Teensy 4.1, Bosch BMI088, Luxonis OAK-D-Lite, NXP PCA9685, Intel Wi-Fi 6 AX200, and Li-Ion Battery Pack with MP2315GJ-Z buck regulators.
- Prepare the custom distribution power board by soldering the MP2315GJ-Z buck regulator components to step down V_BAT to 5V and 3.3V rails for computing and sensor nodes.
2
Hardware Assembly & Wiring
- Mount the NVIDIA Jetson Orin Nano and Teensy 4.1 onto the chassis main deck, routing the UART interface connection (TX, RX, GND) between SBC_HIGH_LEVEL and MCU_REALTIME.
- Install the Bosch BMI088 sensor and wire its SPI bus (SCLK, MOSI, MISO, CS, GND, 3.3V) directly to the Teensy 4.1 for high-frequency inertial data acquisition.
- Connect the NXP PCA9685 PWM driver to the MCU_REALTIME via I2C (SDA, SCL, VCC, GND), and connect the power rails supplying V_BAT to the driver board.
- Plug the Luxonis OAK-D-Lite camera into the NVIDIA Jetson Orin Nano via USB (USB_SS_TX, USB_SS_RX, VBUS, GND) and mount the Intel Wi-Fi 6 AX200 module to the available USB interface.
- Wire the main power distribution to supply 5V to the NVIDIA Jetson Orin Nano, 3.3V to the Teensy 4.1, and V_BAT to the PCA9685 actuator driver.
3
Firmware Setup
- Flash the Teensy 4.1 with the real-time C++ firmware implementing 1kHz kinematics, gait generation, SPI polling of the Bosch BMI088, and I2C commands to the PCA9685.
- Configure the NVIDIA Jetson Orin Nano with Ubuntu Linux, ROS2, librealsense drivers for the OAK-D-Lite, and set up the SLAM navigation and H.264 FPV video encoding stack.
4
Testing & Calibration
- Perform a bench test with the robot suspended in a calibration rig, verifying 1kHz joint servo actuation via the PCA9685 and reading IMU calibration offsets from the Bosch BMI088.
- Test FPV video streaming, stereo depth processing, and AprilTag optical docking routines using the OAK-D-Lite camera and Intel Wi-Fi 6 AX200 link.
