Overview
The most common is the wheel-based system, but you can also find systems such as the legged, wheeled or crawling system. [...]we can have a classification like: * Flow in a tunnel, with vortices as the kinematic principle and hydrodynamic forces as the main resisting force to the movement; * Torsion, with longitudinal vibration as the kinematic principle, and frictional force as the main force resisting movement; * Sliding, with sliding as the kinematic principle and frictional force as the main resisting force to motion; * Running, having as its kinematic principle the oscillatory motion of a pendulum with several joints, and the main force of resistance is the loss of kinetic energy; * Jumping, having as its kinematic principle the oscillatory motion of a pendulum with several joints, and the main resisting force is the loss of kinetic energy; * Walking, with the kinematic principle being the rolling of a polygon, and the main resisting force being gravitational force. The strength of this system is similar to that of any other vehicle, with a chassis at the base, on which the rest of the assemblies and sub-assemblies are placed, such as the locomotive system, engine, bodywork, also providing the necessary strength. 2.2 Classification of rover systems The classification of these types of systems can be done in a branched way, by dividing and classifying the various assemblies found on them [3]. [...]ROVER type systems are classified according to: * Locomotor system: * With legs: \" One leg; \" Two legs; \" Four legs; \" Six legs. * With wheels: \" By number of wheels: * Three wheels; * Four wheels; * Six wheels; * Eight or more wheels. [...]they are adapted to meet the requirements of the harsh environment they are subjected to, such as extreme temperatures and dust. [...]the main elements are: * Chassis; * Body; * Propulsion system; * Steering system; * Communication system. SLA (Stereolithography) * Rapid prototyping technology, widely used in the industrial field to make moulds, models and even functional parts; * It involves using a laser beam with ultraviolet light to solidify a liquid photopolymer resin in the printer's build tank. [...]using software that 'slices' the 3D model into cross-sections, ultraviolet laser light passes through the resin, which solidifies in successive layers resulting in the 3D model; * Materials used: photo-sensitive liquid resins, ceramic materials.
