Assistive robots including assemblies for accommodating obstacles and methods for using the same

A vehicle comprising:

• a base defining a front end and a rear end positioned opposite the front end, the base comprising:
• a chassis body;
• a front conveyor assembly positioned at the front end of the base, the front conveyor assembly comprising:
• a front conveyor defining a conveyor pathway that extends at least partially within the chassis body and a front toe extending outward from the front conveyor;
• and
• a rear conveyor assembly positioned at the rear end of the base, the rear conveyor assembly comprising:
• a rear conveyor defining a conveyor pathway that extends at least partially within the chassis body and a rear toe extending outward from the rear conveyor;
• and
• a front wheel assembly positioned at the front end of the base and coupled to the chassis body, the front wheel assembly comprising a front wheel;
• and
• a controller communicatively coupled to the front conveyor assembly, the rear conveyor assembly, and the front wheel assembly, the controller comprising a processor and a computer readable and executable instruction set, which when executed, causes the processor to:
• direct the vehicle to move toward an obstacle;
• direct the vehicle to move upward in a vertical direction such the obstacle is positioned below the conveyor pathway of the front conveyor;
• direct the front conveyor assembly to engage the front toe with the obstacle;
• direct the front conveyor assembly to move the front conveyor and the front toe in a rearward direction to move the vehicle over the obstacle;
• and
• direct the rear conveyor assembly to engage the rear toe of the rear conveyor with the obstacle.
