Differences between a robot box and an automatic box
Working principle:
* Automatic transmission (AT): Uses a torque converter for smooth gear changes and a planetary gear to vary gear ratios.
* Robotic gearbox (robot): The essence of a manual gearbox in which the clutch and gear shift control are automated using electronics and hydraulics.
Number of gears:
* Automatic transmissions typically have 4 to 10 gears for better fuel economy and performance.
*Robots usually have 5 to 7 gears.
Gear shift:
* Automatic transmission ensures smooth gear shifting thanks to a torque converter.
*Robots may shift gears faster, but shifts may be harsher or more noticeable, especially at low speeds and when downshifting.
Reliability:
* Automatic transmissions are considered more reliable due to the presence of transmission fluid, which lubricates and cools the components.
*Robots may be less reliable due to the complexity of mechanical components and electronics, especially under high stress conditions.
Service cost:
* Automatic transmission service is usually more expensive due to transmission fluid changes and more complex design.
*Robots are usually cheaper to maintain since they are basically manual transmissions with additional electronic components.
Fuel efficiency:
* Automatic transmissions are generally more fuel efficient due to smoother gear shifts and a torque converter that acts as a slip clutch.
*Robotic transmissions may be less fuel efficient due to harsher gear changes and lack of a slip clutch.
Reaction to gas:
* Automatic transmissions respond to pressing the gas pedal more smoothly and consistently.
*Robots may respond faster, especially when accelerating, but the response may be less smooth.
Reviews
Positive feedback about robots:
* Fast and precise gear shifting
* Sportier handling
* More affordable compared to automatic transmission
Negative reviews about robots:
* Harsh gear changes, especially at low speeds
* Tendency to jerk when downshifting
* Less reliable than automatic transmission
Conclusion:
The choice between a robot and an automatic machine depends on individual preferences and priorities. For those looking for a smooth and comfortable driving experience, an automatic transmission may be the best choice. Robotic transmissions offer sportier handling and quicker shifts, but they can be less reliable and less comfortable to drive.
