Decent tractor, that will not be stopped by any hurdle. There is also an electrical tractor version with manual steering available. A combination of high experience in specific electric driven machinery from Elatec, together with partner Rhobahn for the autonomous software. Located in France.
 
In the robotic version, the robust and reliable architecture of the Tract'Elec electrical tractor remains. However, it’s adapted to robotization. The manual cockpit is replaced by a technical for transmission and computing. All sensors and security systems are connected here.
 
Key elements from the tractor fundament:
Large rear wheels, with one engine per wheel
Large front wheels, with electric steering system
Electronic differential management
 
Therfore, this robot easily achieved the following benefits:
Lower soil compaction
High tracktion, less slipping
High steering stability  
Controlled and reduced turning radius

Weeding
A weeding (hoeing) tool can be delivered together with the robot. It’s made up of different coulters and intended mainly for mechanical weeding. The construction is removable, adjustable and upgradeable.
 
Spraying
The robot cultivator can carry spray equipment. The capacity of the tank will be in the order of 300 liters. Different mounting configurations are possible, both in terms of the positioning of the booms and of the tank. The sprayer works with an electric pump (s).
 
Trailer
The robot has a towing hook with pin for towing a trailer. The trailer can reach 500 kg of GVWR under driving conditions with slope <4%.
