Abstract
A skid-steer delivery autonomous ground vehicle has a drive train and suspension that aids in maneuverability. The AGV has six wheels, each of which is powered by its own motor. The AGV has features that diminish the dragging effect on the wheels, either by choice of wheel features or by taking weight off the front wheels during turning.
Claims20
An autonomous delivery vehicle, comprising:
- a chassis;
- two pairs of corner drive wheels coupled to the chassis;
- a pair of mid drive wheels;
- a suspension on each side of a body connected to the chassis and connected between at least one of the mid drive wheels and a first one of the corner drive wheels among the two pairs of corner drive wheels;
- and
- a tire coupled to the first one of the corner drive wheels, the tire configured to reduce dragging during turning of the autonomous delivery vehicle.
3 more elements
An autonomous ground vehicle, comprising:
- a body;
- three pairs of wheels coupled on opposing sides of the body wherein at least one wheel of each pair being coupled to a drive motor;
- and
- a suspension on each side of the body connected between at least two wheels on a same side of the body, the suspension comprising a pivotable arm between the at least two wheels and wherein at least one wheel of the at least two wheels disposed on a front side of the body is liftable relative to the other of the at least two wheels during operation of the autonomous ground vehicle.
1 more element
A vehicle, comprising:
- a chassis;
- a pair of bogie arms coupled on opposite sides of the chassis;
- two pair of wheels coupled, wherein each pair is coupled to each end of each of the pair of bogie arms;
- at least one motor driving at least a first wheel of the two pair of wheels, wherein the first wheel is positioned proximate a mid-point of the chassis, wherein the at least one motor is configured to steer the vehicle by rotating the first wheel on one side of the chassis in a direction opposite to a wheel on the other side of the chassis;
- and
- a tire coupled to a second wheel of the two pair of wheels, the second wheel proximate a forward position of the chassis, the tire configured to reduce dragging during turning of the vehicle wherein second wheel is liftable relative to the first wheel during operation of the vehicle.
