The MCIB is an electronic interface board for mobile robots. It comprises of three 68HC11 programmable micro-controllers and support electronics. The foremost function of the MCIB is the control of 8-16 Polaroid ultrasonic sensors using a University of Michigan-developed method called Error Eliminating Rapid Ultrasonic Firing (EERUF). With the EERUF firing method sonars can detect and reject false readings due to crosstalk or ultrasonic noise, allowing for substantially faster and safer travel. The MCIB connects to a PC-type computer via the parallel printer port and it provides other functions listed below.

The University of Michigan also offers a cable assembly for connecting 8 or 16 Polaroid ultrasonic sensors to the MCIB. The reason for offering this cable assembly is that in order to make them an extraordinarily expensive crimping tool is needed. From our own experience we know that it is a very tedious task to make these cables without the crimping tool.
This photo shows from right to left: female sonar connector as used on the MCIB. Matching male connector. Pins that are crimped onto the cable and pushed into the male connector. Assembled cable. Below the connector parts a regular sewing needle and a match are shown, for size-comparison. |
