CRAWLER

Offroad robotic platform

The Crawler robotic platform is designed primarily for the offroad environment. Durability, terrain capabilities and a low center of gravity are the basis for the robot’s movement in difficult terrain and on unpaved surfaces. The device is thus also suitable for agricultural or research purposes. Crawler can be loaded with an 80 kilogram load.

The base of the robot is a differential track chassis. Extremely quiet and smooth operation is ensured by BLDC motors with worm gearboxes, which are maintenance-free. Durable tracks ensure traction on any surface. The robot meets the IP65 specification, so it can work in any weather. It can be supplemented with a Spinbotics robotic arm, RTV Sensor Box for autonomous movement or other equipment as required.

FEATURES AND TECHNOLOGIES

Quiet

Crawler does not disturb its surroundings. It is ensured by the BLDC drives with worm gearboxes that drive rubber tracks.

Powerful, maintenance-free

Brushless drives and worm gearboxes with a lifetime oil filling guarantee high torque and maintenance-free operation.

Precise

Precise position control of the robot predestines it for operations that require high precision device movement in the environment.

Intelligent

The robot uses AI elements with which it recognizes objects and can, for example, autonomously come to the docking station to recharge.

Strong

The load capacity and high torque predetermine the robot for carrying heavy loads and pulling various tools, for example for tillage.

Universal

The possibility to use the robot in different environments and for different types of tasks makes it an adaptable robotic platform.

APPLICATION EXAMPLES

Crawler for vineyard care

One of the practical applications of the Crawler mobile robot is its deployment in the field of agriculture. An example is the use of the platform in a wine-growing environment, where it found its use as an autonomous device mowing the space between the rows of vine. In addition to its movement, Crawler can also use sensors to collect data intended for disease prediction. The robot can then label the damaged roots with a robotic arm.

AVAILABLE VERSIONS

R&D platform

Basic platform suitable for universities and research institutions for algorithm development. The platform can be supplemented with sensor, software or outputs for other devices as required.

Teleoperator

A platform suitable as a service robot for demanding terrain, controlled by a teleoperator using the RTV Teleop application. Possibility to equip the robot with a sensor system, a Spinbotics robotic arm or other equipment as required.

Autonomous

An autonomous platform designed for outdoor environment. The robot is equipped with an RTV Sensor Box and AVN algorithm. The device moves autonomously in the rows of vine or in an orchard and solves operations such as mowing, local spraying or collection of samples needed to predict diseases.
