Magno-tread

Magno-treads are a technology from the IDW portion of the Generation 1 continuity family.

Magno-treads aids a Transformer when walking on surfaces with low gravity. Using magno-treads makes for tough going and so they aren't used unless needed.

Fiction

IDW comics continuity

When Jetfire and the Technobots were investigating a disturbance on post-cataclysm Cybertron, they discovered the gravity was roughly three-gees weaker than normal. In order to walk, they needed to use magno-treads. Stormbringer issue 1

Notes

• While one year later Cybertron's radiation storms dissipated enough for Transformers to once again inhabit the planet, no mention is made of the gravity returning to normal. Presumably they would all still have difficulty walking.
