What is it?
The Rover RT-P200 is a 100% electric and autonomous spraying equipment developed by Hural, a Brazilian company. It is designed for high-precision operations, covering lines, inter-rows, and total area applications.
How does it work?
The Rover RT-P200 operates autonomously, guided by RTK and Lidar technology. It manages the spraying process through 4 rotary atomisers. The system allows for droplet types described as coarse, medium, or fine. The average speed maintained during the operation trial carried by PCMAF-IPEF was between 4 and 5 km/h. The maximum speed capacity is 14.4 km/h. The height of the boom can be adjusted from 70 to 220 cm. The calculated flow rate used was 10 to 30 L/ha.
• Battery and Logistics: The equipment offers an autonomy of 4 to 5 hours. The time required for battery recharge is 90 minutes. The operational consumption of charge was measured at 3.36 kWh per charge, or 1.12 kWh. The use of an extra tank for preparing the mixture aids in logistics by allowing the recharge point to be programmed in advance.
Operational Results
The Rover RT-P200 maintained a high Operation Efficiency - EO (85%) and Machine Availability - DM (88%) , which are considered coherent values for the reform scenario. The autonomous operation helped reduce accessory and unproductive times by eliminating human interference. The stops for overload acted as necessary safety measures, preventing equipment damage. However, the operational utilisation index (IUO) of 74% suggests opportunities for adjustment to improve the utilisation of the equipment, particularly concerning its adaptation to reform areas featuring higher amounts of residue.
