Roboteq has introduced a magnetic guide sensor that can detect and report the position of a magnetic field along its horizontal axis. The MGS1600 is intended for line following robotic applications, using a magnetic tape to form a track guide on the floor, indicated the company.

According to the company, the sensor uses advanced signal processing to accurately measure its lateral distance from the centre of the track, with millimeter resolution, resulting in nearly 160 points end to end. Tape position information can be output in numerical format on the sensor's RS232 or USB ports. The position is also reported as a 0-5V output and as a variable PWM output.

Roboteq MGS1600. Sensor can detect and report the position of a magnetic field along its horizontal axis.

The sensor will detect and manage up to 2-way forks and can be instructed to follow the left or right track using commands issued via the serial/USB ports, or using the state of two digital inputs. All of the sensor's operating parameters and commands are also accessible via its CAN bus interface.

In addition to detecting a magnetic guide track to follow, the sensor will detect and report the presence of magnetic markers that may be positioned on the left or right side of the track. The sensor is equipped with several LEDs for easy monitoring and diagnostics. The company added that the sensor incorporates a high performance, basic-like scripting language that allows users to add customised functionality to the sensor. A PC utility is provided for configuring the sensor, capture and plot the sensor data on a strip chart recorder, and visualise in real time the magnetic field as it is seen by the sensor.

The sensor firmware can be updated in the field to take advantage of new features as they become available.

Roboteq sells adhesive magnetic tape of 25mm and 50mm width, in 50m rolls.
