Given that operators are working multiple orders concurrently, the laser display and the put to light technology are key elements of the system to ensure maximum order accuracy. As soon as the pick is completed, the pod moves on and the next pod is presented to the operator, a process that takes about 6 seconds to complete. Note that stations can be configured such that the picker also performs the packing function, or one can set these up as two separate functions involving two different people.
This choice tends to be driven by the complexity of the packing requirement whereby more complex packing requirements generally require a separate packing function apart from picking. After the item has been picked, the robot transfers the pod back into storage or to wherever it is needed next.
Note that pods can also be used to stage outbound orders at the work stations. In this situation a pod is used to hold multiple sales orders that are picked by the operator. Once the orders are completed, the pod can then be transported to another part of the warehouse for say packing; or for marriage to another portion of the sales order that is being picked in a different work area of the distribution center. The Material Handling Control Software that manages the Kiva robots and the flow of inventory is perhaps the most important component of the overall solution.
The MHE software is the brain behind the entire operation because it is manages the movement of the robots. MHE consists a fairly complex set of algorithms that are needed to minimize operator dwell time while at the same time ensuring that the number of robots being used is minimized.
In other words, how does one achieve maximum productivity levels with the least amount of capital investment. The amount of thought that has to go into this topic is actually quite interesting. It involves enough optimization algorithms and queuing theory to excite a mathematician. Kiva is one of the few material handling companies that guarantees the performance rates that workers will achieve at the work stations.
The number of orange robots needed to support the fulfillment operation is in part based upon the speed at which operators perform their work. If operators work significantly slower than Kiva's expected rates then the system will be designed with too many robots and conversely if they work significantly faster than the expected production rates then the robots may not be able to keep up with the operators which introduces the risk of dwell time.
In effect, dwell time is the time an operator spends waiting for goods to arrive at a station and it actually causes a reduction in productivity rates as a result. Hence this is a balancing act that needs to be determined up front through a detailed simulation effort to ensure that the system is implemented optimally. The MHE software automatically decides where to move and store each pod within the Kiva floor plan.
To this end, not all pods are treated equally. The frequency of "hits" associated to the SKUs stored within a pod plays an important role in determining where the pod is stored within the plan.
The highest velocity pods are positioned nearest to the picking work stations to minimize the transit time to and from these stations. As well, hyper-fast items may be purposely spread across multiple pods to ensure concurrent availability to multiple work stations. Wireless Network: Kiva robots continuously broadcast their location within the distribution center by reading the 2D floor-mounted labels.
At the same time, the robots receive directions from the MHE system which runs on a centralized computer that broadcasts instructions through the wireless network. Conventional Wi-Fi routers, mounted in the warehouse rafters, broker these communications to the server.
Professional Services: The final component of the Kiva solution is professional services which are an essential requirement to ensure success of the operation. The typical implementation requires about six months to set up the software and warehouse grid system, simulation modeling, testing and training.
This is not an area that should have corners cut for the sake of expediency or cost reduction. First, it is critical for Kiva to run a simulation of the operating environment to ensure that the required number of robots is specified correctly.
The simulation needs to take into consideration the number of pods, work stations, operator task requirements, operator performance rates, need for the robots to have battery charging breaks, need to handle peak volumes, and need for redundancy. Second, an efficient floor plan and highway grid needs to be designed based on the number of pods required to support the SKU variety within the distribution operation. A typical floor plan calls for blocks of 10 pods i.
It is possible to store pods in a multi-deep environment such that the robot must move pod A in order to access pod B. This is a strategy that may make sense for slower moving SKUs where the pods are required less often. Pods can also be stored on mezzanines through the use of elevators. The robot simply moves the pod into an elevator where it is moved to another floor. Third, this is a system that involves a high degree of automation and human interface, hence all human processes need to be clearly defined to enable the robotic system to be designed appropriately.
Does the picker simply perform picking? Does the picker need to scan the SKU being picked to verify pick accuracy? Does the picker need to create a packing carton with a label? How many orders does the picker select concurrently? Are there any value added functions that the picker must perform as part of the pick and pack process e.
These examples serve to illustrate that the work processes being performed at the Kiva work stations have an impact on the productivity rate of the order picker, hence they also have an impact on the rate at which the robots need to be queued at the work station to prevent operator dwell time. Fourth, there is a customized software interface that must be constructed to integrate the Kiva MHE application to the WMS or ERP software that runs the balance of the distribution center. There may also be a need for customized enhancements to be made to the Kiva software to support any particularities of a distribution operation.
Fifth, training of the operators and support for go-live is required. Lastly, on-going support services are needed.

Subscribe to Robohub mailing list. The motor can initiate the spin which allows the wing to straighten out due to centrifugal forces. F-SAM could be a good toy but it may not be a good alternative to quadcopters if the objective is conventional aerial photography or videography.
However, it can be a good contender for single-use GPS-guided reconnaissance missions. As it uses only one actuator for its flight, it can be made relatively cheaply. It is also very silent during its flight and easily camouflaged once landed. Various lightweight sensors can be integrated onto the platform for different types of missions, such as climate monitoring. F-SAM units can be deployed from the air, as they can also autorotate on their way down, while also flying at certain periods for extended meteorological data collection in the air.
We have a few exciting projects on hand, most of which focus on 'do more with less' theme. This means our projects aim to achieve multiple missions and flight modes while using as few actuators as possible. This platform, published earlier this year in IEEE Transactions on Robotics , is able to achieve two flight modes autorotation and diving with just one actuator. It is ideal for deploying single-use sensors to remote locations. For example, we can use the platform to deploy sensors for forest monitoring or wildfire alert system.
The sensors can land on tree canopies, and once landed the wing provides the necessary area for capturing solar energy for persistent operation over several years. Another interesting scenario is using the autorotating platform to guide the radiosondes back to the collection point once its journey upwards is completed.
Currently, many radiosondes are sent up with hydrogen balloons from weather stations all across the world more than 20, annually from Australia alone and once the balloon reaches a high altitude and bursts, the sensors drop back onto the earth and no effort is spent to retrieve these sensors. By guiding these sensors back to a collection point, millions of dollars can be saved every year—and also [it helps] save the environment by polluting less.

Shopify paid nearly a half-billion dollars for the acquisition to help its customers compete with Amazon. In June , Shopify launched its Fulfillment Network service that it said will speed up delivery times and lower shipping costs for its customers. Its industrial automation portfolio in consisted of delta, gantry and SCARA robots, as well as vision components and systems. KUKA had a mobile robot of its own at the time, but it was more a work-in-progress compared to those offered by Swisslog.
At the time, Swisslog primarily operated in healthcare- and warehouse distribution-related applications. At the time of the deal, Kiva said it would continue to sell its solution to third-party companies.
Amazon renamed Kiva Systems to Amazon Robotics and the technology is now used solely in-house. This left a technology gap in the industry, which led to the creation of various warehouse automation startups. Locus Robotics and 6 River Systems are perhaps the best examples of the trickle down effect caused by this deal.
After its Kiva robots were no longer supported, it took matters into its own hands and developed its own robots. It ran this project in stealth for about three years before spinning out Locus Robotics.
Had Amazon not purchased Kiva Systems, Locus Robotics and many others in the space might not exist today. He can be reached at [email protected].
