We designed and built a 12 degree-of-freedom (3 servos per leg × 4 legs) quadruped robot controlled by a Raspberry Pi Pico W, featuring integrated environmental sensing and a wireless WiFi controller. Starting from a custom CAD body and 3D-printed frame, the robot combines mechanical engineering and embedded electrical engineering to create a platform capable of coordinated four-legged locomotion, heading determination, environmental mapping, and target detection. In order to do so, our system leverages several sensors including an IMU, a solid state LiDAR sensor, and a contact-less infrared sensor.
This article details a $30 ESP32-based room mapper built with a Time-of-Flight sensor and IMU. It features 64-zone 3D visualization, real-time orientation tracking, temporal filtering, plane fitting, and a mapping mode. The project is breadboard-based and doesn't require soldering, but relies on an IMU for heading, which can cause inaccuracies if the device is moved.
ROSbot is a ROS powered 4x4 drive autonomous mobile robot platform equipped with LIDAR, RGB-D camera, IMU, encoders, distance sensors. Available in versions 3, 2R, 2 PRO, and 2.
