Four wheel driving and steering vehicle with Suspension System
4WD eXplorer is a ROS wheeled Ackermann steering mobile robotic platform which can be used for a large variety of applications and to speed up your robotics research! As with our other platforms, it is possible to easily add your own sensors or you can ask us to integrate them for you depending on your requirements. Usually, 4WD eXplorer is equipped with 360° Laser Sensor, RGB-D camera, motor encoders, current sensors and RTK GPS able to provide a very high accuracy for autonomous guidance. Thanks to its 10 inches off-road wheels, it can be used both for indoor and outdoor applications and its high payload allows the users to add additional devices and laptops. Moreover, it provides several power output in order to connect multiple devices. The large ground clearance lets the vehicle to overcome obstacles like rocks and debris.
The electric vehicle can be used to explore different types of terrains since it is equipped with two side swing arms able to pivot around a central axis to perform a rocker type suspension system. Both arms have a wide swing out so the vehicle can easily overcome large rocks and debris.
The large 10 inches tube type tyres are both for off road and indoor use by providing excellent performances in all applications. Their air pressure can be adjusted depending on the soil profile in order to reach an extra grip during terrain traversal routines.
4WD eXplorer comes with a well-documented ROS node which allows the user to remotely control the robot and to easily integrate sensors, devices and actuators. It also includes C/C++ library for cross-platform development and for third-party integration. The user can move the robot by using the standard geometry_msgs ROS messages.
The vehicle is based on the classic ackermann steering system with four drive wheels able to rotate around their vertical axis. Each wheel assembly includes a brushless motor with a 1024-pulses optical encoder and a DC gearmotor to perform the vertical axis rotations.
The vehicle integrates a rocket suspension system based on two swing arms able to rotate around a horizontal axis while anchored to a set of dampers; this design is essential to keep the main frame as stable as possible even on rough terrains by enhancing the efficiency of the sensors (i.e. cameras, lasers and IMUs) installed on the vehicle.
4WD eXplorer is not afraid of the night! Thanks to a powerful 20W headlight with 1580lm mounted on its front and rear bumpers, you can face the night without problems! You can use this vehicle for surveillance or for inspections in no light conditions and in rough environments since both lights are IP67 and come with LED technology.
