Abstract

Described herein are robotic platforms and associated features that may have applicability in a wide variety of applications and industries, but that may have particular applicability in automotive testing and testing of vehicles having autonomous or semi-autonomous driving features. Robotic platforms may include a low-profile chassis, one or more rotational elements coupled to one or more drive motors and supported within the chassis, and a control system coupled to and controlling the drive motor(s). Also disclosed are suspension systems that may maintain the chassis of a robotic platform above the ground in use but that allows the chassis to ground out when subject to a pre-determined load, thereby spreading the load across the chassis.

Claims28

Dependent claims

A robotic platform for automotive testing, comprising:

a low-profile chassis including a substantially planar top surface and one or more substantially vertical side surfaces at least partially enclosing an interior;
at least one first rotational element supported within the chassis interior, the at least one first rotational element being coupled to a drive motor;
a control system coupled to the drive motor and configured to control the drive motor;
wherein the at least one first rotational element is supported within the chassis interior by a suspension, wherein the suspension is configured to support the chassis above the ground when supporting a soft target, and wherein the suspension is configured to allow the chassis to ground out when the chassis is subjected to a pre-determined load greater than the load when supporting the soft target.
