Abstract

A transporter for transporting a first person and one or more riders over a surface. The transporter includes a first support platform for supporting the first person, the first support platform having left and right sides and defining a fore-aft vertical plane and a lateral plane. At least one ground-contacting element is coupled to the first support platform such that the first support platform is capable of tilting in the fore-aft plane about a tilt axis. The at least one ground-contacting element is driven by a motorized drive arrangement so as to cause locomotion of the transporter. A controller commands the motorized drive arrangement. The controller is configured so that at least one of fore and aft sustained motion of the transporter is based at least on fore-aft tilting of the first support platform. One or more passenger platforms support one or more riders, the passenger platforms coupled to the first support platform such that fore-aft tilting of the first support platform is substantially independent of the one or more passenger platforms.

Claims

1. A transporter for supporting a first user and at least one rider over a surface, each rider having a first and second foot, the transporter comprising:

a first support platform for supporting the first user, the first support platform having left and right sides and defining a fore-aft vertical plane and a lateral plane;

at least one ground-contacting element coupled to the first support platform such that the first support platform is capable of tilting in the fore-aft plane;

a motorized drive arrangement for driving the at least one ground-contacting element so as to cause locomotion of the transporter;

a controller for commanding the motorized drive arrangement, the controller configured so that at least one of fore and aft motion of the transporter is based at least on tilting of the first support platform;

one or more right support platforms for supporting the first foot of the at least one rider; and

one or more left support platforms for supporting the second foot of the at least one rider.

2. The transporter according to claim 1, wherein at least one right ground-contacting element is coupled to at least one of the right support platforms;

and wherein at least one left ground-contacting element is coupled to at least one of the left support platforms.

3. The transporter according to claim 1, wherein at least one of the right support platforms is coupled to the first support platform such that fore-aft tilting of the first support platform is substantially independent of the at least one of the right support platforms, and wherein at least one of the left support platforms is coupled to the first support platform such that fore-aft tilting of the first support platform is substantially independent of the at least one of the left support platforms.

4. The transporter according to claim 1, wherein the controller commands the motorized drive arrangement such that stability of the first platform is dynamically maintained.

5. The transporter according to claim 1, wherein the right and left ground-contacting elements are one of a wheel, a ski and a skid.

6. The transporter according to claim 1, wherein the first support platform includes:

a first pivot member characterized by a first pivot axis proximate to said tilt axis for coupling at least one of the right support platforms to the first support platform; and

a second pivot member characterized by a second pivot axis proximate to said tilt axis, for coupling the at least one of the left support platforms to the first support platform, wherein the first and second pivot axis are perpendicular to the fore-aft plane.

7. A method of using a transporter to transport a first user and at least one rider over a surface, the at least one rider having a first and second foot, the method comprising:

supporting the first user on a first support platform, the first support platform defining a fore-aft vertical plane and a lateral plane, the first support platform coupled to at least one ground-contacting element such that the first support platform is capable of tilting in the fore-aft plane;

supporting the first foot of the at least one rider on a right support platform, the right support platform coupled to the first support platform such that fore-aft tilting of the first support platform is substantially independent of the right support platform, the right support platform coupled to at least one right ground-contacting element;

supporting the second foot of the at least one rider on a left support platform, the left support platform coupled to the first support platform such that fore-aft tilting of the first support platform is substantially independent of the left support platform, the left support platform coupled to at least one right ground-contacting element such that sustained motion of the transporter is based at least on fore-aft tilting of the first support platform.

8. The method according to claim 7, wherein controlling the motorized drive arrangement is based at least on maintaining dynamic stability of the first support platform.
