Fig. 1 Two robots at a glance.
One robot is already tested in real rooms; the other is our next design. Each column describes only its own robot, so you can compare them without mixing details.
FROM PROJECT NOTESSource brief:§0
Each column is bound to one robot. Values come from the project notes; anything that would need the code to confirm is left out.

Fig. 2 Footprint, drawn to scale.
AMR4's base is 0.52 × 0.63 m and Hardware Bot's is 0.45 × 0.25 m, so AMR4 is slightly wider and about two and a half times as long. AMR4's base carries four mecanum wheels; Hardware Bot runs on two hub motors and casters.
FROM PROJECT NOTESSource brief:§0
Both outlines use the same scale: Hardware Bot is 0.45 × 0.25 m and AMR4 is 0.52 × 0.63 m.
