Hardware
Overview
Botzo hardware components are aimed at being affordable but still of decent quality. The components can be summarized by the following 4 types:
- Processing Unit: Raspberry Pi 4 (future: Jetson Nano).
- Actuators: Optimizing torque for robust movement (25kg servos x3 per leg).
- Power Supply: Batteries capable of delivering ~30 minutes of runtime under typical conditions.
- Sensors: Integrating components for environmental awareness. Botzo top is universal base for attaching fourther components, such as webcam and LiDAR.
