Alpsmotion is a world’s leading Hexapod Walking Robot design
studio engaged in the development strength-weight ratio and high performance of
electronic integrated mechanical solutions. Alpsmotion have been accumulated
more than five years fundamental R&D in robotics. Except for robotics
innovation, we are patents holders of inventions related to Infinitely Variable
Actuator IVA, which also the same means of variable mechanical transmissions
continues gearbox. Or call infinitely variable transmission (IVT) and continuous
variable transmission (CVT).
A brief survey paper to overview the IVT and CVT technology
nowadays or the pass.
However, what’s the differences compare Alpsmotion IVA with
other comment worldwide use of IVTs and CVTs.
Alpsmotion’s IVA (or IVT/CVT)
is a specific type of I/CVT (the infinitely/continous variable transmission).
in which the range of ratios of output shaft speed to input shaft speed can includes
a zero ratio that can be continuously approached from a defined higher ratio. A
zero output speed (low gear) with a finite input speed implies an infinite
input-to-output speed ratio, which can be continuously approached from a given
finite input value with an IVT. Low gears are a reference to low ratios of
output speed to input speed. This low ratio is taken to the extreme with I/CVTs,
resulting in a "neutral", or non-driving "low" gear limit,
in which the output speed is zero.
Because continuously variable transmissions are built with
fewer parts compared to conventional transmissions, they are less expensive to
manufacture. This savings is passed along to consumers in vehicle’s selling
price and improving a vehicle’s fuel efficiency.
Alpsmotion’s IVA (or IVT/CVT) can transfer substantial torque, because
their static friction actually increases relative to torque throughput, so
slippage is impossible in properly designed systems. Efficiency is generally
high, because most of the dynamic friction is caused by very slight transitional
clutch speed changes.
Alpsmotion’s IVA (or IVT/CVT)
can offer better efficiency when compared to other CVTs as in the preferred
range of operation because most of the power flows through internal gear
system. Torque transmission capability can also be increased. There's also
possibility to stage power splits for further increase in efficiency, torque
transmission capability and better maintenance of efficiency over a wide gear
ratio range.
Alpsmotion’s IVA (or IVT/CVT)
is a "continuous variator with infinite ratio and neutral'" using at
least four point contact gears , this
natural high rigid attribute can which can transfer high impact. So make it can
be used on any transmission (esemoio: gasoline, diesel, natural gas), wind
turbines, or steam, human power bicycles , electric motors, as well as a large
number of industrial or agricultural applications, replacing the current
transmissions.
Alpsmotion’s IVA (or IVT/CVT) can offer both precise and back- drivabilities.
Significantly, this is the critical point that make this mechanism applied on
robotics industry. Due to it must supports electric motors both CW and CCW rotation
in a precise way.no slippage is allowable. So it support robot to compliance
control and force control with built in encoder to open loop control or close
loop control.
Choosing Alpsmotion’s
IVA (or IVT/CVT) , the torque
control by the same motor can support up to 700% torque. This breakthrough
technology not only empowering electrical motors very high anti-impact
capabilities and make it close to the hydraulic motor performance, but also empowering
electrical motors have high bandwidth to speed and torque control.
