Remote controlled vehicle
A remote controlled vehicle includes a chassis, front and rear axles mounted on the chassis and at least one wheel coupled to each axle. A front hydraulic drive drives the front axle and a rear hydraulic drive drives the rear axle. The remote controlled vehicle includes front and rear control valves in fluid communication with the corresponding front and rear hydraulic drives for regulating at least one of a fluid direction and a fluid flow through each control valve to each corresponding hydraulic drive. A controller communicates drive commands to each hydraulic drive and receives the drive commands front an external communicator. The chassis has a width substantially equal to the widest width of the reservoir and the motor.
1. A remote controlled vehicle comprising:
a chassis;
front and rear axles mounted on respective front and rear portions of the chassis;
at least one wheel coupled to each axle;
front and rear hydraulic drives disposed on the respective front and rear portions of the chassis, the front hydraulic drive driving the front axle and the rear hydraulic drive driving the rear axle;
front and rear control valves in fluid communication with the corresponding front and rear hydraulic drives for regulating at least one of a fluid direction and a fluid flow through each control valve to each corresponding hydraulic drive;
a motor driving a fluid pump in fluid communication with the hydraulic drives;
a reservoir in fluid communication with the fluid pump, the reservoir disposed on the chassis rearward of the controller and forward of the pump and motor, the pump being disposed on the chassis forward of the motor; and
a controller communicating drive commands to each hydraulic drive, the controller receiving the drive commands from an external communicator;
wherein the controller, the reservoir, the motor and the pump are disposed in series along the chassis, the chassis having a width substantially equal to the widest width of the reservoir and the motor.
2. The remote controlled vehicle of claim 1 , wherein the chassis has a length of between about 80 inches and about 160 inches, a width of between about 10 inches and about 30 inches, and a height of between about 10 inches and about 30 inches for moving through tunnels.
3. The remote controlled vehicle of claim 1 , wherein the controller receives radio frequency communications from the external communicator.
4. The remote controlled vehicle of claim 1 , wherein the drive system and the controller are each sealed watertight to remain operational while submerged in water.
5. The remote controlled vehicle of claim 1 , wherein the rear hydraulic drive drives the rear axle independently of the front hydraulic drive.
6. A remote controlled vehicle comprising:
a chassis;
front and rear axles mounted on respective front and rear portions of the chassis;
at least one wheel coupled to each axle;
front and rear hydraulic drives disposed on the respective front and rear portions of the chassis, the front hydraulic drive driving the front axle and the rear hydraulic drive driving the rear axle;
front and rear control valves in fluid communication with the corresponding front and rear hydraulic drives for regulating at least one of a fluid direction and a fluid flow through each control valve to each corresponding hydraulic drive;
a motor driving a fluid pump in fluid communication with the hydraulic drives;
a reservoir in fluid communication with the fluid pump; and
a controller communicating drive commands to each hydraulic drive, the controller receiving the drive commands from an external communicator;
wherein the controller, the reservoir, the motor and the pump are disposed in series along the chassis, the chassis having a width substantially equal to the widest width of the reservoir and the motor; and
wherein the remote controlled vehicle has a center of gravity disposed within a volume having a length of between about ⅛ and about ½ of the length of the chassis, a width of between about ⅛ and about ½ of the width of the chassis, and a height of between about ⅛ and about ½ of the height of the chassis, the volume centered and sitting on the chassis.
