Your score on GrabCAD is not terribly important, but it is nice to have a better score, and not be "ranked" dead last on a site with four million users. What can you do to increase your score?

Mobile, military robot optimized for use in desert environments which can be controlled remotely or autonomously and can collect/ stream video to a VR headset via its front mounted camera. The method of movement is a continuous track, created using steel roller chain connected by fasteners with 3D printed links. These loops sit on a custom designed drive sprocket and idler sprocket with 4 shock absorber loaded roller pins that act as the suspension system. The drive motors are powered by '18650' batteries, directed by a raspberry pi 4 and connected to a motor controller. For connectivity, a mobile device can connect to the pi's external antenna as it is a WiFi access point. From here, directions can be sent to the robot from the mobile device using the Node Red GUI and additionally, the entirety of the main raspberry pi computer can be accessed for the use of sending custom commands for autonomous movement.

Spur gears have their teeth cut parallel to the axis of the shaft on which the gears are mounted, transmitting power between the parallel shafts. To maintain a constant angular velocity ratio, two meshing gears must satisfy a fundamental law of gearing: the shape of the teeth must be such that the common normal at the point of contact between two teeth must always pass through a fixed point on the line of centers. The contact point is called the pitch point. The goal is to assess the maximum stress during the transmission of the torque. By engineering judgement, the maximum stress occurs either at a contact point or at the root of a tooth due to the bending of the tooth. Since there is no restriction of deformation in the depth direction, i.e.,the gears are free to expand (or contract) in the depth direction, so it is modeled as a plane stress problem.

Explicit dynamics is a time integration method used to perform dynamic simulations when speed is important. Explicit dynamics account for quickly changing conditions or discontinuous events, such as free falls, high-speed impacts, and applied loads. Because these “nonlinear dynamics” are integrated into the simulation, explicit dynamics is the preferred choice for simulating highly transient physical phenomena. Some side impacts involve a vehicle travelling sideways into rigid roadside objects such as trees or poles. Often this is the result of a loss of control on the part of the driver, owing to speeding, misjudgement of a corner or because of a skid in slippery conditions.

The seal which is used in the door of applications from automotive industries. The seal is a long strip of rubber and it will be modeled as a plane strain problem. A series of material tests has been conducted, including the uni-axial tensile test, the bi-axial tensile test and the shear test. A series of trials of data fitting shows that, for these material testing data, the two-parameter "Mooney-Rivlin Hyperelastic Model" fits the data better than other models. It is decided to use Two-Parameter Mooney-Rivlin Model. The unit system used in this tutorial is "U.S. Customary (in-lbm-lbf-s)".

Topology optimization is a mathematical method which spatially optimizes the distribution of material within a defined domain, by fulfilling given constraints previously established and minimizing a predefined cost function. Main aim of this tutorial is optimizing and decreasing the material density of the triangular bracket as 50% by topology optimization.

In this tutorial i have used keyshot software for animation purpose. I have used a 3D model of a High Bypass Turbojet Engine for denomsration. It took couple of hours to create the animation video that's why i have skipped that part from the video.
