# HumbleDave2
2025-04-03: REINCARNATING HUMBLE DAVE due to Pi5 I2C failure on GoPi5Go
Originally a reincarnation of ROSbot Dave (rosbot-on-gopigo3) atop
ROS2 Humble and Ubuntu 22.04 (ROS2-GoPiGo3)
**Autonomous ROS2 home robot based on GoPiGo3 and Raspberry Pi 4**
ROSbot Specs:
- Platform: GoPiGo3 from ModularRobotics
- Processor: Raspberry Pi 4B
* 1.8 GHz Max
* Four Cores
* 4GB Memory (Configured with 1GB swap)
* Onboard Dual Band WiFi
- OS: Ubuntu 22.04 LTS 64-bit Server
- ROS2 Humble Hawksbill: Uses 100% of one core (uptime 15min load 1.0)
- Control Interfaces:
* ssh over WiFi
* ROS2 Humble Hawksbill
* 2.4GHz Wireless USB "SNES" Gamepad
- Sensors (GoPiGo3 Intrinsic)
* Battery_Voltage (GoPiGo3 intrinsic)
* Regulated_5v_Voltage (GoPiGo3 intrinsic)
* Magnetic Wheel Encoders 720 cnt/rev (GoPiGo3 intrinsic)
- Sensors (Raspberry Pi Intrinsic)
* Processor Temperature
* Processor Low Voltage Throttling Active / Latched
* Processor Temperature Throttling Active / Latched
- Sensors (Added):
* YDLIDAR X4 - 360 degrees, 12cm-10m range on half degree increment, ~8Hz scanning
* MPU9250 Inertial Measurement Unit
also provides ambient temperature
