Maybe too much time
I found an outdated Roomba 581 vacuum robot in the attic. I just couldn’t throw it away, so I decided to pimp it a little.
A new hobby project was born!
Prototype: Release version:
After all, the Roomba hardware is a good vacuum, and it offers a serial interface to read sensors and control the actuators. Only the robot brain and navigation systems are really outdated. I decided to give it a new brain with better navigation hardware, and reuse the Roomba platform as a whole. Here are the ingredients:
Raspberry Pi Zero 2 W as the new 64 bit brain running Ubuntu Linux
YDLiDAR X4 2D 360 degrees laser scanner
Small OLED display for better user interaction and feedback
MPU6050 6-DOF IMU to measure relative orientation, acceleration and velocity
HMC5883L magnetometer
Control software based on ROS (Robot Operating System)
What I am planning
There is a lot of stuff going on behind the scenes. After all the goal was to create a fully autonomous system, which is a quite complex task. So I am planning a series of postings here covering the following topics:
Low level hardware interface
Navigation stack with SLAM and AMCL, simple navigation and efficient vacuum path finding
Overall system debugging and tuning.
So stay tuned! I will link the posts here as soon as they are ready.
