Description
Anatis assists farmers by fully autonomously performing mechanical weeding tasks. Thanks to its rear 3-point hitch linkage, the flexibility of this collaborative robot means it can perform a variety of jobs using various tools. Carré says its experience in mechanical weeding ensures that the machine is truly effective. Its inter-row hoes and comb harrows have been adapted to optimise its work. The robot is electrically driven by two- or four-wheel motors and is guided by RTK GPS and an optical camera system to detect plant rows. It has an interchangeable lithium-ion battery pack capable of 7.5 hours of autonomous work.
Drive train type
The robot is electrically driven by two- or four-wheel motors.
Characteristics
Anatis is equipped with a 3-point category 1 hitch linkage for mounting standard tools. Lifting travel is 530mm, limiting any risk of friction during loading and crossing phases. A 350kg lifting capacity on the lifting ball joints ensures mission flexibility. The three mounting positions for the bolted hitching arms allow adapting lifting to the tool in use. Accurate adjustments are possible along the last 10 centimetres of cylinder travel. This allows adjusting lifting to match the tool used to ensure accurate work.
An emergency stop button is in the centre of the remote-control panel to quickly stop the robot, even from a distance. An emergency stop system is also provided. To allow manual movement and motion, a dead man’s switch is located on the left-hand joystick. The remote control has a control range of up to 500 m.
Navigation system
Anatis has a dual Trimble GPS antenna for improved signal reception. A dual lens high resolution camera enables the robot to act as soon as the plant reaches 3 cm in diameter. The guidance system uses a sideways motion system integrated into the controlled lifting function using electric jacks.
The robot has an invisible safety barrier. A (Lidar) laser scanning system is located at the front on the retractable mast and provides 265° vision. A LED system located at the front of the carrier indicates when Anatis is active. A light unit located on the top of the robot shows its motion mode (manual/automatic).
