You can build your own Erwhi Hedgheog. It is completely open source under MIT license.
You can easily achieve state-of-art navigation and object detection.
Erwhi Hedgehog uses a standard ROS stack, so every ROS software is compatible.
Erwhi Hedgehog is easily upgradeable and customizable.
Erwhi is an open source project about advanced robotics.
The mission is to achieve an acceleration in robotics development and study, so it is based on the most used robotic framework.
ROS allows to connect lots of different sensors, easily customize hardware and develop complex algorithms.
Sengi is the smallest and fastest rodent.
The Sengi carrier board is a very small board based on STM32F103.
This board contains motor controller with feedback, battery monitor system and a powerful dcdc.
Sengi hardware is programmable using STM32 Cube MX, mbed, Arduino and supports FreeRTOS. A ROS node based on ROS Control stack is provided.
