4.1 SPECIFICATION
The SPIDER AUTONOMOUS 2.0 is a self-propelled machine with four-wheel
drive, controlled by a remote control or driven autonomously using DGNSS
(a global navigation satellite system that provides real-time differential correc-
tions), inertial navigation and sensors. The unique way of steering the wheels
stands out for its high maneuverability both on flat ground and on slopes. The
base of the machine is a square rigid frame which is slidingly connected to
the sliding frame. The center of the sliding frame houses all the propulsion
components such as the internal combustion engine, the tandem hydraulic
fluid pump and two hydraulic motors, the control unit, as well as the dome and
antennae of the navigation components. At the bottom of the frame, on the
outside, are the tethers at the ends of which the four cutting blades are fixed.
An electromagnetic clutch is inserted between the main drive pulley and the
motor. The mowing deck is four-blade. The outlines of the circles describing the
cutting knives do not overlap. The casing protecting the mower deck extends
circumferentially beyond the path of the mower blades. The blades are fixed,
mounted between flanges and tightened by central bolts. The housing has a
recess on the input/output side where the material enters the machine. These
openings are protected by a metal-chain hinge and a rubber screen to prevent
unwanted parts from escaping. Above the rubber hinge, a steel barrier is fixed
on the outside to define a safe distance from the cutting blade. Travel is pro-
vided by four wheels mounted on the end portal gears. The wheels are driven
by two hydraulic drive motors with V-belts. Wheel turning is provided by an
electric motor. Steering is carried out by remote control with Bluetooth module
(hereinafter BT) or by transmitting on a specific UHF frequency.
