Hyundai acquired Boston Dynamics

In 2021, Hyundai Robotics acquired Boston Dynamics, Inc.

Hyundai Motor Group is actively developing the robotics field as a future growth engine for the 4th industrial revolution. In 2021, they acquired ‘Boston Dynamics, Inc., a US robot company, and developed a ‘Factory Safety Service Robot’ equipped with artificial intelligence-based software.

According to the Hyundai Robotics team, the robotic market is expected to increase as it expands into various fields. Recently, mobility-specialized companies are increasing their investment to link technology with artificial intelligence and manufacturing fields. For example, under the goal of ‘Progress for Humanity.

Hyundai and Kia Motors recognized this as a ‘customer-oriented manufacturing platform implemented with technology’ and unveiled ‘E-FOREST,’ a smart factory brand. E-FOREST is ‘Auto-FLEX,’ meaning flexible and advanced assembly, logistics, and inspection automation; ‘Intelligent,’ meaning the establishment of an AI-based autonomous control system; It aims for three values, ‘Humanity,’ and plans to open up the infinite possibilities of future mobility by organically connecting people, nature, and technology.

The most significant value of Hyundai Motor Group is ‘people-oriented.’ This is why Hyundai Motor Group puts excellent effort into robot R&D. This is because the more precisely the robot evolves, the safer and more convenient life can be. The robotics field is one of the five new businesses that are the future growth engine of Hyundai Motor Group. The three robot fields – wearable robots, service robots, and micro-mobility – are the answer to the age of the 4th industrial revolution and an aging society, where advanced technologies and concerns about technological alienation coexist.

FedEx Delivery Robot

Roxo operates on sidewalks, bike lanes and roadsides, and is designed to be used in a three-to-five mile radius of a retailer’s location. We specifically designed Roxo for reliable, autonomous last-mile delivery that can deliver to a customer’s door, including climbing the curb, traveling up the sidewalk, and climbing deep terrace steps.

Further testing is being planned, targeting customer use cases like auto parts, pizza delivery, home improvement, general merchandise, and groceries.

The Effect of Voltage on the Performance of Stepper Motors

Under different voltages, the performance of stepper motors will be different. Generally, the higher the voltage, the better the speed and torque performance of the stepper motor. However, increasing the voltage also causes an increase in current, which may overheat the motor and possibly even damage the driver.

The motor’s low-speed vibration will be larger when working under high voltage. We recommend that the driving voltage be selected according to the size of the motor base (but may be limited by the driver).

Motor Voltage
NEMA8—17 12-24VDC
NEMA23—24 24-48VDC
NEMA34 36-60VDC
NEMA42 60-100VDC

To properly drive a stepper motor at different voltages, the following points need to be considered:

Current: The stepper motor has a rated current, the best working current considered in the design. If the current exceeds the rated value, the electric
The machine may overheat and be damaged. At different voltages, the current may vary. To protect the motor, a current limit can be used
driver to control the current.

Driver: An appropriate driver must be used to drive the stepper motor at different voltages properly. The driver should be able to input
The voltage adjusts the output current to maintain a constant current. This can be achieved using a constant current source driver, which automatically adjusts the
output voltage to maintain a constant current.

In summary, stepper motors work at different voltages as follows: A change in voltage causes a change in current, so you need to use an appropriate driver to protect the motor and achieve optimum performance. When designing the system, the rated voltage and current of the motor should be considered, an appropriate driver should be selected, and control strategies should be used. Source
