The conceptual model creation is described in the following article: IVANOVA, Ioana and Stefka NENOVA, Computer Graphics as a Means of Increasing the Quality of Military Education, Report, Sofia: Yearbook of the Military Academy, 2013, pp. 141-155; http://rnda.armf.bg/wp/wp-content/uploads/2015/03/Binder-1-322.pdf; ИВАНОВА, Йоана и Стефка НЕНОВА, Компютърната графика като средство за повишаване качеството на военното образование, Доклад, София: Годишник на Военна академия, 2013, стр. 141- 155, http://rnda.armf.bg/wp/wp-content/uploads/2015/03/Binder-1-322.pdf ANIMATION PROCESSES: 1. Animating the model: it is performed by creating keyframes in the track under the working space that can be adjusted, changed and deleted. 2. Animating a camera: it is analogously to step 1. 3. Rendering process: it is required to be completed before saving the final image or animation in a desired format.

The conceptual model creation is described in the following article: IVANOVA, Ioana and Stefka NENOVA, Computer Graphics as a Means of Increasing the Quality of Military Education, Report, Sofia: Yearbook of the Military Academy, 2013, pp. 141-155; http://rnda.armf.bg/wp/wp-content/uploads/2015/03/Binder-1-322.pdf The development of spherical robots dates back to the 1990s. Their advantage is that they move in all directions, and most often this happens with changes in the center of gravity. Some models use a system of counterweights, which helps to stay still on slopes with an inclination of 33° (Pico Rover). Some are used to study the environment, others - on the lunar surface. They are usually equipped with a high-resolution camera. The robot is tentatively named by the author VESPER-006 ("Vesper" means Venus) due to the fact that the planet Venus is a "double" of the Earth due to the close dimensions, although the surfaces of the two planets are completely different. The spherical shape was purposefully chosen to make the robot to resemble the planet it was inspired by. VESPER-006 is thought to be with an innovative design and drive method. It is suitable for research and analysis of the environment regardless of what it is (air, liquid or field). The temperature range is also wide (between -40 and +120°C). The mechanism must be able to reach the point with coordinates (x, y, z) in time space [t]. The design is stylish, simple and facilitates the rotation of the robot around its axis, as well as its movement in space. The dimensions must be such that they can take the weight of the engine and equipment. Apart from an aesthetic purpose, to make the design more interesting, the three side elements (Stands) have been added for their practical function - to stabilize the robot when it is in a static position. The main steps in the modeling process are as follows: 1. Modeling the side element: first a curve with the desired shape is drawn using Create > Shapes > Line. After that it is extruded by Modifier Panel > Extrude tool. To edit the object, right-click on it and select Convert to Editable Poly. The model can be modified by selecting individual polygons, edges or vertices and using the Extrude and Bevel tools. 2. Clone the side element: by right-clicking on it and selecting Clone. 3. Modeling the spherical body: the outer Geosphere is transformed into a grid by selecting all polygons, Inset and Extrude. The selected polygons should be removed.

Open Material Editor (hotkey "M"): the main settings of the material (ambient, diffuse, glossiness and specular level) are shown in Step 1. 2. Coloring the inner sphere: it should contrast to bring out the golden material of the outer grid. An example is given in Step 2. 3. Adding lights and shadows: this is one of the most complex stages of modeling in 3DS Max, usually done right before animating the model. It should be noted that lights can also be animated. They are selected from the main menu Create > Light. The favorite light of the author is Omni. Each of the lights can be adjusted appropriately to produce realistic shadows and highlights.

The aim of this practice is to build a printable model of the “HARMONY” laboratory (ISS Module), which means that it is advisable to avoid too much detail, i.e. the level of abstraction should be medium, not high. The main steps are as follows: 1. Modeling the body: transform a cylinder by drawing the figure shown in step 1 using Sketch > Polyline, Three Point Arc, or Spline on the top base of the primitive. Finding the center of the base is done by Sketch > Project and clicking on it. The hole in the center is modeled by Construct > Extrude after drawing a circle. Before constructing the cylindrical hole by pushing in the center part of the top base, the top part of the cylinder can be cut by Construct > Subtract and after copying with Ctrl+C/ Ctrl+V, it can be placed in the bottom part of the cylinder. Its rotated by the Move/Rotate tool by 180° along the relevant axis. The opening on the bottom base is constructed by drawing a 2D profile with the appropriate shape and rotating it along the vertical axis using the Construct > Revolve tool by 360°. 2. Clone the figure on the upper surface: the figure must then be copied a specified number of times using the Circular Pattern. 3. Modeling an additional component: it is constructed by transforming a cylinder 3 mm high and 20 mm in diameter, drawing curves on its upper base using the method described in step 1.
