“ It's time to say goodbye to the weight, and the outside of the skeletal muscles is bringing in new solutions.
At a time when the robotics and physical intelligence industry are rampant, in addition to human robots under the spotlight, another billion-square-foot race track is hosting explosive landing cracks and wearable smart devices that are flourishing in areas such as medical rehabilitation, outdoor mountaineering, special weights and retirement assistance.
However, the long-term restriction of the external skeleton from the bone marrow laboratory to the core of the bone marrow remains on the power supply of the joints.
Worn as if dragged by an iron frame, the reverse drag resistance is no higher than that of the large, and the wearer's slightly more active force must be strongly opposed to the motor; the traditional joint motor thickness is too large, the shell board sticks, the whole machine is out of shape, the weight is amazing, the wear experience is greatly discounted; while the integrated module seems economical, the installation structure is tightly locked, which in turn limits the design space of the outer shell machine.
What kind of dynamic joints do the outer bones need?
At CIIF in China, CubeMars, a well-known robot-powered brand, presented the perfect solution to the AKE series of direct-drive joint modules designed specifically for external skeletons and wearable devices, as well as the world's first two supercompact members: AKE40-6 and AKE50-8.

Small deceleration versus + decelerator built-in: compress the lightweight with the large torque to the center of the hand
In the case of external bone applications, the axial dimensions of the motor directly determine the natural degree and beauty of the attachment of the device to the human bone.
Conventional pump servo motors + large-speed decelerator pumps are often very clumsy, while the CubeMars AKE series uses innovative direct-drive QDD architecture designs.
The first is to directly embed precision gear reduction devices into the geometry center of the motor, breaking the vertical stacking of the traditional structure, and greatly compressing the axis to the dimensions, giving the entire module a wheel-like extreme flatness. More difficultly, the small gear reduction ratio does not sacrifice power. The CubeMars relies on the long-term accumulation of rotor magnetic circuit optimization and high pit saturation.

Design philosophy of seamless, non-driven seams: giving customers the freedom to integrate completely
At a time when many manufacturers were seeking high integration, the AKE series went the other way, opting for a reduction in the vision of machinery engineering: go outdoors, go to integrated drive boards.
Why do we have to do such a reduction?
The outer skeleton is essentially the second layer of the human body, with each brand's fastening system, carbon fiber brackets, protective sealing grades and aesthetic design that varies. AKE saves the heavier general overcoat, and automakers can follow their own product's lifecycle curve, designing the thinnest, most recognizable, and most efficient customized overcoat. Removing the drive panel is also due to space and weight sharing considerations: if each unit is self-driving, not only will it squeeze the limited horizontal space, but it will also squeeze the weight at the end of the body's limbs control; to focus the electricity to the waist or back core control, the lines will be tighter, the unit will run more balanced, and the entire unit will wear fatigue to a minimum.

Extremely slippery anti-drive: allowing algorithms to be truly integrated into a shadow-and-random human machine
Not only do the bones of the body have to be able to make muscles, but they also have to be able to obey the muscles.
When the wearer moves, turns, or even disconnects electricity, the joints must be able to be driven with extremely low resistance to external force. If the resistance is high, the wearer will not only not save energy, but also increase consumption.
The AKE series direct drive modules are inherently ultra-low reverse drive torque.
On the one hand, the small deceleration compared to the structure makes transmission losses extremely low, mechanical transparency is very high, and the machinery of the machine is very small; on the other hand, the algorithm and the hardware's seamless resonance, when the engineer's intentions are recognized and the instructions under the smooth control algorithm, AKE can achieve a non-secondary response, man moves instantly, man stops. Users do not feel the vibration and resistance of mechanical transmission, as if the skeleton grows a natural human muscle.

AKE40-6 and AKE50-8 are surprisingly on the field, the whole matrix is together.
In the past, CubeMars has successfully mass-produced AKE60-8, AKE80-8, and AKE90-8, three large-to-medium-sized specification models that have been widely used in heavy-duty outboard skeletons, quadruped robots, and industrial transportation equipment.
In order to fully penetrate the market for consumer-grade assistance, light outdoor climbing and medical-grade light rehabilitation, CubeMars officially released two new specifications: AKE40-6 and AKE50-8.
What is the strength of the two new products? Let's take a look at some of the highlights of the field test.
AKE40-6: Lightening the weight of the elven shark by breaking the weight limit
It weighs only 140 g, has a diameter of only about 51 mm and a thickness of 24.5 mm; the deceleration rate is 6:1, the rated voltage is 24 V, the rated torque is 1.8 N. m, and the peak explosion torque is up to 5.5 N. m. It is worth mentioning that its anti-drive resistance is as low as 0.05 N. m.
In scenographic positioning, it is oriented mainly in three directions: one is the daily lightweight pedal guidance with vertical straightening, such as foot-to-toe support braces, anti-cramping joint backrest assistants, and highly sensitive lightweight pedal straightening equipment; two is the upper extremities with lightweight recovery outer bones, such as the delicate bending of the wrist joints, the fingers grasping the power source of the outer bones, and the lightweight upper arm synchronous muscle compensation equipment; and three are the ultra-thin consumer support braces, which, with 140g of self-loading and 0.05 N.m. of ultra-low anti-drive, can be fitted seamlessly into the daily braces or wear a knee brace, achieving the power of the senseless, zero-traction braces.
AKE 50-8: Small steel cannon fired under the size of gold
It weighs only 190 g, has a diameter of about 61.2 mm and a thickness of only 22.5 mm; decelerates at 8:1, has a rated torque of 2.5 Nm, the peak explosion torque jumps to 7.5 Nm; the reverse torque is only 0.09 Nm, and the back gap is only 9 arcmin.
Scenario positioning: in knee aids and walking aids, available for daily lightweight aids, silverside walking aids and knee load unloading equipment; in industrial and rehabilitative upper limb outer bones, available for waterline shoulder lifting, tool lifting, elbow joint muscle compensation equipment; and in lightweight flexible walking guidance and rehabilitation equipment, with ultra-low anti-drive resistance, achieve zero-trailer sensory pace rehabilitation training.
From small to large, from 140g supersonic to 170 Nm high-torque flagships, the CubeMars AKE series has built the industry's most competitive direct-driven outboard torque matrix.
