internet ШУУД ҮЗЭХ commerce matures,
consumers are expecting more immediate delivery of goods, but a fleet of drones won't do any good unless the packing warehouses can keep up. The latest effort to help speed up this process comes from Fetch Robotics, which has unveiled Fetch and Freight – a robotic tag team that takes over the boring task of collecting and delivering stock.
Fetch and Freight may sound like an end-of-pier act, but their purpose
is to make the job of human shipping workers faster and easier. Designed
for the logistics industry, robotic team consist of a mobile base and
an advanced manipulator that can act as either a static or mobile unit.
The robots use the ROS open-source robot operating system, and include
anti-collision systems to help them work in the vicinity of humans.
The basic purpose of Fetch and Freight is to take over the pick-and-pack
and other repetitive warehouse jobs, so workers can concentrate on more
complex tasks. In addition, they can carry out autonomous, continuous
operations by means of a charging station that the robots can use by
themselves to top up their batteries and minimize downtime.
Fetch
is an advanced mobile manipulator that uses a back-drivable arm with
seven degrees of freedom and a modular gripper, which can be switched
out and replaced depending on the task. It's set on a telescoping spine
that can stretch from a height of 1.1 to 1.5 m (3.5 - 4.9 ft). Together,
they can lift about 6 kgs (13 lb). The pan-tilt head holds cameras and a
3D depth sensor, and can seek out and select items from standard
shelves. The mobile version is installed on a Freight base.
Freight is the mobile base that works in tandem by following Fetch or a
human worker. It can carry about 68 kg (150 lb), and has a 2D laser
scanner for navigation. It can be programmed by means of a smartphone
app to navigate a particular route, or to follow Fetch or a human worker
using wireless signals.
In basic warehouse operations, Fetch and Freight work together with
Freight seeking out stock items on shelves, then transferring them to a
basket carried by Freight. When the order is complete, Freight heads off
to packing, while a second base unit moves in to replace it, so there's
no pause in the work.
"Consumers are increasingly acting like impatient toddlers when it comes
to delivery; they want their purchases and they want them now," says
Rob Coneybeer, Managing Director at Shasta Ventures. "As a result of
this trend, commercial order fulfillment is becoming more and more
challenging for retailers. A robotic system such as the one from Fetch
Robotics can address these issues and ultimately lead to healthier
margins, competitive advantage, and satisfied customers."
The robots will go on display at the 2015 IEEE International Conference
on Robotics and Automation (ICRA) running May 26 to 30 at the Washington
State Convention Center in Seattle.
