Abstract:
This paper describes the design and implementation of the SEA, Ltd., Brake and Throttle Robot (BTR). Presented are the criteria used in the initial design and the development and testing of the BTR, as well as some test results achieved with the device.

The BTR is designed for use in automobiles and light trucks. It is based on a servomotor-driven ballscrew, which in turn operates either the brake or accelerator. It is easily portable from one vehicle to another and compact enough to fit even smaller vehicles. The BTR is light enough so as to have minimal effect on the measurement of vehicle parameters. The BTR is designed for use as a stand-alone unit or as part of a larger control system such as the Automated Test Driver (ATD) yet allows for the use of a test driver for safety, as well as test selection, initiation, and monitoring.

Installation in a vehicle will be described, as well as electronic components that support the BTR. Operational modes and controls will be examined, followed by testing and results. The paper will close with an evaluation of the BTR and a brief view of possible future avenues of development and testing.
