pib pro prototype and BOM

pib pro – Concept Overview

pib pro is a best effort prototype with home use case motivation

pib pro goal is to be envisioned as a general-purpose humanoid robot designed for home environments, capable of performing a wide range of daily tasks. Upgrading pib edu into a pib pro model requires major redesigns across mechanics, electronics, compute, and actuation.

For the first iteration, we will develop a functional prototype using off-the-shelf actuators, a reduced number of degrees of freedom, and an entry-level NVIDIA Jetson Orin module rather than the industry-grade Jetson Thor. This prototype will validate the core architecture before moving to custom actuators and full-scale hardware.

Target Capabilities of pib pro

• Payload Handling:
  Able to safely and smoothly manipulate loads up to 5 kg.

• Battery Endurance:
  Supports 2 hours of continuous operation on battery power.

• Perception & Processing:
  Efficient onboard processing of both audio and visual streams with low latency suitable for real-time interaction.

• Locomotion & Balance:
  A dynamically balancing lower body that enables stable, reliable locomotion across typical indoor environments.

Actuation

Actuator sizing is mentioned in detail in https://pib-rocks.atlassian.net/wiki/spaces/kb/pages/638451715 and robstride actuators to be used are tested and explained in https://pib-rocks.atlassian.net/wiki/spaces/kb/pages/612663297 . The table below explains which motors are used in which joint. Robstride actuators are used everywhere where smooth control and high strength is neeeded, In joints that interact minimally with the environment like neck, waveshare STS3215 motors are used.

Sensors

pib pro uses same sensors that are in edu version, especially for audio IO but the higher end models, additionally it adds extra sensors that weren’t needed in the edu version.

Electronics and drivers

pib pro does not use a raspberry pi, instead it uses Nvidia Jetson Orin as the main computer, it also uses some of the tinkerforge chips like Tinkerforge hat and relay for power control

Battery

pib pro uses Lithium iron phosphate battery 48 volts
