O-Part detector

O-Part detectors are scanning devices used by the Autobots to track down the last five O-Parts. They were developed by T-AI.

After the "rescuing" of Doctor Onishi from the Predacons, the location of the O-Parts was made top priority, and T-AI was able to construct O-Part detectors. Using the first of the detectors, the Autobot Brothers located the third O-Part in a stone pillar. They were joined by the Build Team. The construction Autobots had a second detector, and informed them that Optimus Prime had suggested a race to find the most O-Parts.

With the guidance of Doctor Onishi and the O-Part detectors, the two teams were soon racing across the Earth in search of the elusive artefacts. Despite the interference of Sky-Byte, Megatron and the Decepticons, all seven O-Parts were recovered by the Autobots.
