DPRG RBNV - Robot Builders Night Virtual - January 7, 2025

Welcoming back from the Christmas break and wishing a happy New Year. Sharing special moments and updates.

Newcomers in the call introducing themselves before diving into discussions with Tom, Chris, Paul, and Pat.

Tom talks about developing a camera-based object detector using esp32 cams for detecting orange cones and exploring machine learning object detection.

The speaker discusses a compact package containing nickel metal hydride batteries and their specifications.

A USB power delivery device by FNI RSI, the DPS 150, is mentioned, emphasizing its features and capabilities.

The speaker mentions outdoor robots and expresses interest in exploring and working with them in the future.

A conversation about cameras, processors, deployment environments, and smart camera technologies, with a focus on different camera models.

Details about hardware development for robots, including the use of Raspberry Pi and microcontrollers, along with discussions on specific motor drivers and compatibility.

A demonstration and discussion on remote access to Raspberry Pi using RPI Connect, enabling screen sharing and remote shell capabilities.

Information about an immersive theater production involving robots and interactive performances, with details on the setup and experience for the audience.

Discussions on robotic models, pricing, availability, and pre-orders, highlighting a specific robot model called 'Jenny' with pricing details.

Conversations on GPS technology, including differential GPS implementations on GitHub and the transition to RTK GPS for improved accuracy.

Discusses the variability of GPS configurations from 10 centimeters to 100 centimeters depending on the circumstances without needing an absolute reference. Emphasis on base station, GPS receiver, and communication with the robot.

Touching on the use of digital radios for communication between base station and rover, considerations for GPS corrections, and the challenges of high-frequency digital radio links.

Narrative of disassembling a hoverboard with a 36-volt lithium-ion battery pack and brushless DC motors, leading to potential robot-building ideas and excitement for the project.

Mentions experiences with lean boards, potential risks involved, and the need for safety precautions, including the idea of limiting speed for safety purposes.

Discusses the capabilities of a robotic vacuum cleaner in detecting obstacles, potential tasks like laundry sorting or picking up dog poop, and distinguishing between items of different heights.
