The mechanical team is responsible for the design and maintenance of every robot in use along with developing competition obstacles required for competition preparation. Members use various tools such as Solidworks, ANSYS CFD, or ANSYS FEA to optimize the mechanical design of the robot and to conceptualize and build sub-assemblies.
This year, the mechanical team consists of several experienced members and many newcomers. Therefore, training new members and providing them with meaningful work while experienced members provide advice and guidance was crucial to the team’s success.
Due to the complexity of the design, and the larger size of the mechanical team in recent years, it is further divided into the following sub-teams:
This team designs the frame of the robot to ensure it is rigid and structurally sound while being lightweight and cost effective. Finite Element Analysis and other structural calculations are completed by this team. The team consists of 4 to 5 members that are accountable for CAD modelling, drawings, and assembly.
The hull team develops the hull assembly of the robot which includes designing the structural components and the waterproof sealing mechanism. The team consists of 3 experienced members so there is little room for error in the design. These members model and review the assembly while documenting changes thoroughly. Also, the hull team is responsible for creating drawings and coordinating with machine shops to build the assembly.
The mechanical claw team designs, builds, prototypes, and tests the servo actuated gripper that will be integrated with Arctos. Furthermore, the team consists of 3 members that are highly skilled in 3D printing, mechatronics, and troubleshooting.
The marker dropper team designs and builds the servo actuated marker dropper system for Arctos. There are 2 members responsible for the entirety of the design.
The torpedoes team consists of 3 first year engineering student members and 3 experienced members. This year the torpedoes assembly underwent an enormous revamp where ARVP moved away from a compressed gas actuated system to a spring-based one. As a result, this team designed several iterations of a torpedoes concept while implementing design calculations such as kinematics, Hooke’s Law, and the conservation of energy laws to optimize the design. In the coming months, the team will 3D print and build the torpedoes assembly. Additionally, 2 members are devoted to creating another torpedoes assembly concept using sheet metal installed in strategic areas to prevent wear and tear.
The electronics tray team works on the layout and mechanical construction of the electronic housing for Arctos. The team consists of 4 members that focus on designing the trays to be spatially efficient, lightweight, and accessible while ensuring they are cost effective. Furthermore, these members carry out interdisciplinary roles by communicating with the electrical team regarding design considerations.
The newest addition to the ARVP Mechanical Team workflow is the continuous improvement team. This team focuses on all aspects of the robot and helps optimize cross-team designs where it is needed. An example of their work is when the team worked with the Software and Control Team to develop a testing apparatus to measure thruster performance. Additionally, the team estimated and researched a water cooling system for future applications. Some areas of expertise include Computational Fluid Dynamics, beam calculations, Finite Element Analysis, and CAD modelling.
