"Aurrino PRIMA e-wagon provides the most natural use experience, as easy as pulling an empty wagon, other e-wagons require frequent manual adjustment." Lots of the reviews of Aurrino Prima e-wagon and feedback from users highlight the remarkably natural smooth using experience, and we know from our inbox that many in the Aurrino community are keen to know just why this is.
To explore these topics in detail, we are publishing a series of blogs looking into Aurrino's technology. Today we're looking at the force sensor, which plays a hugely important role in the natural smooth operation.
Why a force sensor?
If you know even a little about e-bikes or robotics and how they work, you've no doubt heard a lot about sensors. Some high-performance e-bikes use similar force-sensor technology inside, the e-bike with the force sensor offers a smooth and natural pedaling experience. In high-safety devices such as collaborative robots or medical robotic arms, highly sensitive force sensors are often integrated. These sensors keep the operator and equipment safe and automatically slow down or stop working in case of contact.The traditional e-wagon needs to constantly adjust the speed knob and switch the direction in use. You have to concentrate on driving it.
This is a relatively simple technology, install a knob on the handle, turn it when needed to get the desired speed, and switch another switch when you need to go backwards. As a "manual" control method, it is slow to respond and depends on your proficiency and concentration, just like we play remote control cars. They are usually suitable for running in open places, if you pass through a small space or someone next to you, the wagon will not stop quickly, nor will it be very convenient to step back or turn, the wagon always lags behind the state we want, and it is easy to crash. As a result, it can feel "out of control" when used in small Spaces.
A force sensor, in contrast, measures the amount of force the operator is exerting as they use, allowing the motor to be much more responsive to the actual conditions. It is therefore smoother and more intuitive for the user. An additional advantage of force sensors is that they are more efficient in regards to the battery's power; power-assistance is only engaged when the user applies pressure, so when braking or coasting, no battery power is wasted.
The PRIMA force sensors
PRIMA's force sensors are specifically designed for the e-wagon based on robotic control technology. When used, the handle will detect forces from different directions, and even the presence of torque. Standard force sensors do not recognize and distinguish them, causing the wagon to run out of control. Aurrino's force sensors can accurately identify the required forces, filter out data that affects operation, and detect data up to 1,000 times per second for extremely high response speed.
Lots of research and development lie behind the torque sensors in Aurrino Prima e-wagon. The system includes a intelligent algorithm that has been designed following tens of thousands of times real-life starts, stops, acceleration and deceleration, to simulate asphalt, grass, gravel roads in urban and outskirt scenarios. This guarantees the most natural-feeling and bionic running experience. This algorithm connects to both the sensor and the motor, ensuring the communication between the two is real-time, closd-loop and super-responsive to the operating conditions.
