Question

1. for which pair of drivetrains is it true that the robot could not drive sideways without turning?

a. tank drive, standard 2 - wheel drive
b. mecanum drive
c. holonomic drive, tank drive
d. mecanum drive, holonomic drive
e. standard 2 - wheel drive, h - drive

Explanation:

To solve this, we analyze each drive type's capabilities:

• Standard 2 - wheel drive and 4 - drive (likely 4 - wheel drive): These use traditional wheel setups where wheels rotate forward/backward. Lateral (sideways) movement isn’t possible as wheels can’t move perpendicular to their rotation axis without skidding uncontrollably.
• Other options (like Mecanum, Holonomic, Tank, or their pairs) allow sideways movement: Mecanum/Holonomic use special wheel designs for omnidirectional movement; Tank drive can turn in place but not strictly sideways like Mecanum, but the pair in E (standard 2 - wheel + 4 - drive) can’t move sideways.

Answer:

E. standard 2 - wheel drive, 4 - drive
