The plan is to first get things working with sonar, then ditch the ultrasonic sensor and switch entirely to vision-based navigation. The goal? See how far computer vision alone can take us, and how it stacks up against traditional sensor.

New project. New excitement. New robot. 🤖🔥

We’re building an autonomous Raspberry Pi–based robot, starting with ultrasonic sensing and a Pi Camera for navigation and obstacle avoidance.

FOLLOW and LIKE for the updates.

Did you know also that SpeedyBee flight controller can be connected to a Raspberry Pi and used for your robotics project? 🤯🤖

The image shows a simple UART connection:
TX → RX
RX → TX
GND → GND

This lets Raspberry Pi handle AI, vision, ROS, while the flight controller manages real-time control.

Pixhawk + Raspberry Pi Zero 🚁
A classic companion computer setup for flying robots.

UART via TELEM1 + stable 5V BEC power lets the Pi run MAVROS, while Pixhawk handles flight control.

Perfect for:
🤖 ROS-based autonomy
👁️ Computer vision
🧠 AI onboard drones

The L298N motor driver is still a robotics classic 🤖

✔️ Drives 2 DC motors
✔️ Direction + speed control via PWM
✔️ Easy to use with Arduino/ESP32
✔️ Perfect for line followers & rovers

Great for learning motor control fundamentals before moving to advanced drivers.
