For part (a), since no time constraint is given one can assume F mg to balance the forces, and E mgh (the potential energy of a mass lifted to height h). For (b), a force F (g a)m is applied from t 0 until t T / 2, and F (g a)m is applied from T / 2 to T.

This must be sufficient to raise the elevator a distance h in time T. Given the symmetry of the problem, instead consider the interval of time from 0 to T / 2. Since v at, integrating one obtains distance h / 2 aT2 / 2, and thus a 8h / T2 so that the maximum force is F (g 8h / T2)m.

For (c) with a counter-mass, everything is the same except that m is replaced by (m mc). Thus with a counter-mass approximately equal to the mass of the elevator almost all energy must be devoted to the elevator cargo rather than the elevator itself, as well as to overcoming the frictional forces that have been neglected here. However, since elevators with high-g forces are not very desirable as passenger conveyances (except in amusement parks), the system must limit the maximum acceleration when the load is below the maximum amount it can lift.

. Energy harv esting Articulation can be helpful in generating energy. For example, raising a solar panel above ground cover can lead to large gains in the available sunlight, with still larger gains if the panel is angled towards the Sun rather than resting flat. By dithering the orientation of the panel by small amounts and recording which leads to the largest electricity generation the panel can be adaptively pointed to achieve the best return.

Against this must be balanced the cost of moving the panel, which can be very small if it is properly mass-balanced. One can also imagine systems that send out creepers so that power generation takes place in regions with favorable sunlight, while sensing takes place in locations of greater interest..

Example 12. code128b for None 8 Following the Sun Assume that a flat solar array is in an equatorial location with an unobstructed view from horizon to horizon. Neglecting increased atmospheric losses near the horizons, by what factor is energy generation over a day increased if the array moves to point towards the Sun compared with it being in a fixed horizontal position Solution Energy generation is proportional to the effective area integrated over time.

The geometry of the fixed array relative to the Sun is illustrated in Figure 12.5..

Since the angles to the Sun are uniformly distributed over this interval, the energy collected is proportional to. p=2 Z 0 2 2 r sin d r 0:64r p p as opposed Code 128A for None to r if the array always points towards the Sun. Thus a gain of 56% in energy collection is possible, although efficiency near the horizon is always less due to increased scattering and the likelihood of cloud cover..

12.2 Interaction of mobile and static nodes Deployment Code 128 Code Set B for None and maintenance of a static network always requires some set of mobile agents, such as student researchers. Indeed a very large part of the design effort is devoted to minimizing the frequency of use of such mobile agents, who tend to be expensive to maintain. However, when autonomous mobile robots are available there can be large consequences for the network architecture.

This section discusses some of the ways in which static and mobile nodes may interact to increase the capabilities beyond those of either alone. Robotic ecologies The optimal mix of mobile and static nodes depends upon their relative costs. Mobility over land, unless supported by infrastructure, is costly in terms of energy and in general very difficult to achieve, with barriers such as stairs, fallen trees, sandy slopes, mud, and the like.

Thus perhaps the most practical scenario is for there to be a large number of low-cost static nodes for each mobile node, along with either infrastructure or higher-cost nodes to provide energy and long-range communications. On water by contrast, mobility is relatively inexpensive and most nodes may be mobile. Even so there are advantages to specializing functions so that not every node carries the same sensing, locomotion, communication, and energy-generation or storage resources.

The basis of network design is to consider these functions separately and to work out how the network as a whole can be designed to achieve the best performance for a given cost. The worst approach is to attempt to devise a supernode that can take on all the varied functions of a student researcher. It is the system, composed of varied components, that must be designed to take on a small subset of these capabilities in an automated fashion, with many tasks reserved for the humans who interact with it.

The better the applications and deployment environments are known, the less overdesign or human intervention is needed. Thus over the course of a long-range study the configuration of elements in the field will change. From this point of view the various components form an artificial robotic ecology, in which static nodes (that may have articulation) and other infrastructure take the role of plants while mobile robots take on the role of animals.
