Abstract

A mobile platform structured for mounting a soft target thereon is provided. The mobile platform includes a self-propelled drive unit configured to move along a ground surface responsive to a control signal. The mobile platform also includes a hardened mobile platform control module coupled to the drive unit so as to move with the drive unit. The mobile platform also includes a sacrificial body structured and coupled to the drive unit so as to move along the ground surface with the drive unit.

First claim

What is claimed is:

1. A mobile platform comprising:
a self-propelled drive unit configured to move along a ground surface responsive to a control signal;
a hardened mobile platform control module coupled to the drive unit so as to move with the drive unit; and
a sacrificial body structured and coupled to the drive unit so as to move along the ground surface with the drive unit,
the drive unit and the control module being connected by one or more breakaway connections structured to enable the control module to separate from the drive unit responsive to a collision of the mobile platform with another object.

2. The mobile platform of claim 1 wherein the drive unit comprises a self-balancing scooter.

3. The mobile platform of claim 2 wherein the body is attached to a frame of the self-balancing scooter.

4. The mobile platform of claim 1 wherein the drive unit is configured to be remotely controllable.

5. The mobile platform of claim 1 wherein the control module is attached to the body.

6. The mobile platform of claim 1 wherein the control module includes a hemispherically-shaped housing.

7. The mobile platform of claim 1 wherein the control module is configured to generate commands directed to controlling movement of the drive unit, wherein the drive unit is configured to be controllable to move responsive to commands received from the control module, and wherein the control module is in operable communication with the drive unit.

8. The mobile platform of claim 1 wherein the body comprises a body first portion coupled to the drive unit so as to move along the ground surface with the drive unit, a body second portion separate from the body first portion, and a coupling mechanism structured to couple together the body second portion and the drive unit so that the body second portion moves along the ground surface with the drive unit, the control module being attached to the body second portion.

9. The mobile platform of claim 8 further comprising a separation mechanism structured to be operable to separate the body second portion from the drive unit after disabling of the coupling mechanism and responsive to a control command, so as to enable the body second portion to move along the ground surface separately from the body first portion.

10. The mobile platform of claim 9 wherein the coupling mechanism comprises:
a drive unit coupling member coupled to the drive unit;
a body second portion coupling member coupled to the body second portion, the body second portion coupling member being structured to be mateable with the drive unit coupling member; and
at least one pyrotechnic fastener structured to maintain the body second portion coupling member and the drive unit coupling member in a mated condition prior to deactivation of the at least one pyrotechnic fastener,
and wherein the at least one pyrotechnic fastener is structured to be deactivable to enable the body second portion coupling member to unmate with the drive unit coupling member.

11. The mobile platform claim 10 wherein the separation mechanism comprises a pressurized gas source interposed between a portion of the body second portion coupling member and a portion of the drive unit coupling member, and wherein the pressurized gas source is structured to be activable to generate a pressurized gas having a pressure sufficient to unmate the body second portion coupling member and the drive unit coupling member after deactivation of the at least one pyrotechnic fastener.

12. The mobile platform of claim 11 wherein the pressurized gas source comprises at least one squib.

13. The mobile platform of claim 9 further comprising one or more processors and a memory communicably coupled to the one or more processors and storing an autonomous control module including instructions that when executed by the one or more processors cause the one or more processors to generate a control command resulting in operation of the separation mechanism so as to separate the body second portion from the drive unit.
