A magnetic guide sensor that detects and reports on the position of a magnetic field on the horizontal axis for the movement of robots on the factory floor was announced by Roboteq, Inc. The sensor targets line-following robotic applications and uses adhesive magnetic tape for the floor-level track followed by the robot.Advanced signal processing accurately measures lateral distance from the track’s center, from a height up to 60mm. The MGS1600 provides a position resolution of 1mm, according to the company, the highest precision available.



The sensor moves material on factory floors that use automatic guided vehicles (AGVs), however new applications are expected to develop in retail, medical, stage theater and rail-less tramway industries. Connectivity options abound with the technology. It is also equipped with several LEDs for easy monitoring and diagnostics.

The sensor is available now globally at $395 in single quantities.

In the early seventies I worked at Odetics in Anaheim California. A brilliant engineer by the name of Steve Bartholet (since passed away) implemented just such a system for delivering mail around the plant.
His system used a single strand of wire taped to the floor with duct tape and the "cart" used two pickup coils mounted under the unit that kept the delivery unit following the preset track signal.
The system used a mid frequency signal, about 10 khz I believe, that was picked up by the two coils to keep the cart on track. The system worked great.

I worked as a Co-op in Souther Railways motor shop in 1969 and they had a wire embeded in the floor and pavement between buildings. There were pauses for doors to open triggered by lever switched. The vehicles had a pod on the front that tracked the wire. It had been in use several years. So it amuses me when this technology is annouced as if it were new. A better implementation with more bells a whisteles perhaps, but not new. ;-).
