"You can think of it that way, but it's not exactly right, because this design doesn't use wheels for direct movement, but tracks instead,"
"Tracks?"
When Rocky mentioned such an unfamiliar term, not only was Hammerfire stunned; Orton, Aniye, and Pelaya were equally taken aback. All four of them turned their gaze to him in unison.
In response, Rocky didn't elaborate much but simply walked over to the small blackboard in the research lab. After erasing the various formulas that had been written there, he took a piece of chalk and sketched a track, saying:
"This is a track, just a simple concept I had in mind. It's essentially a flexible chain loop driven by several wheels."
"This thing..."
As Rocky roughly sketched the shape of a track, Hammerfire hopped down from the table, walked up to the blackboard, and climbed his special little ladder, looking closely.
After a while, he took the chalk from Rocky's hand and briskly sketched a detailed diagram of the track's structure!
