New robot project

This is a new long-term robot project I have been working on for the past couple of months. It is a general purpose indoor robot, that will work as a platform for experimentation. When designing this robot, I have tried to think about and improve everything I have learned from previous robot projects I have made. But this robot will also feature some new stuff I have not tried before. Some of the key features if the robot includes:

  • Stepper motor based four-wheel-drive skid-steering drive system
  • Big Li-Ion battery
  • A lot of custom 3D printed parts
  • Heavy duty bumpers, large ground clearance and large foam wheels
  • Raspberry Pi main computer
  • Arduino Due for controlling low-level peripherals
  • Scanning Lidar sensor
  • Probably a Raspberry Pi camera module mounted on a pan/tilt system

So far, only the majority of the mechanical work is done. Here are a few images, click on them to make them larger:

DIY 3D printer detailed overview

This video is a detailed overview of my DIY coreXY 3D printer. It is just over a year since I built it. Some things have changed since then, but most of the machine it the same. This is my first and only 3D printer, I use a few times a week, sometimes more often than that. The printer works very well, it produces high-quality parts while requiring very little maintenance.

Obstacle avoidance robot

This is my attempt at building a really good obstacle avoidance robot. The robot is built to drive around a normal indoor environment without getting stuck on stuff. The robot uses an Arduino Maga 2560 and several sonar sensors to detect obstacles.

This robot also has a Raspberry Pi and camera module, that will be used for computer vision experiments in the future.
