Blind-Drivable Vehicle Demonstrated
The National Federation of the Blind (NFB) challenged research universities and technology companies to design a car that would allow a blind person to drive with the same freedom as a sighted person. To meet this challenge, researchers from Virginia Tech’s Robotics and Mechanisms Laboratory (RoMeLa) partnered with TORC to adapt its ByWire XGV, a mobile robotics research platform, and some of its advanced perception and navigation technologies to work with its non-visual interfaces: the DriveGrip and SpeedStrip. With the help of RoMeLa’s vibrating gloves and seat pad, the driver receives instructional cues as to how to operate the vehicle. The driving decisions that a typical autonomous vehicle would carry out by itself were instead communicated to the blind driver, through the non-visual interfaces, who has full control over the vehicle and made all active driving decisions.
With safety being paramount in such a challenge, TORC’s integrated SafeStop wireless emergency stop system, which provides remote pause and disable functionality, is used to safely bring the vehicle to a controlled stop at the push of a button. Manual stop buttons are also mounted inside and outside the vehicle for additional safety, as well as the SafeStop’s handheld transmitter unit. EAO’s Series 84 E-Stop switch was selected for this critical function.
Series 84 E-Stops offer a unique low back-of-panel depth at just 19 mm maximum, possible illumination, single “mono-block” construction, and a twist-to-release actuator. These product attributes allow for greater flexibility in applications ranging from handheld pendants to machinery and medical equipment. EAO’s Series 84 E-Stops are rated at 3A 120VAC and 1.5A 240VAC, and are protected against oil and water to IP 65 standards. Series 84 E-Stops meet international safety specification ISO 13850 and comply with EN IEC 60947-5-1 and EN IEC 60947-5-5 requirements.
