Motocross Board - MXB Shocker

Project Type: Propulsion and Levitation

Project Information

Project Description:

The task is to analyze the performance and specifications of the MXB Shocker Model R and construct a similar device of equal capability.  The Motocross Board is a two-wheeled, off-road vehicle that rides similar to a snowboard due to a front-wheel swivel.  It is powered by a 48-V, 10-AH, LiFePO4 battery pack and a 3.35 HP brushless motor.  The front and rear wheels support the vehicle weight with coil-over-damper shocks and swing-arm suspension.  The Board has a maximum speed of about 30 mph and is equipped with a chain-sprocket transmission and rear disc brakes.  The goal of the Project is to take an existing idea and improve the concept by testing an evolving prototype.

Team Roles

Electrical Engineer (2) – The Electrical Engineers on the project are responsible for the battery, motor, motor controller, and all other electrical systems, including a “dead man’s switch”.  In addition, the Electrical Engineers are responsible for a system that can recharge the battery in the field from a car or truck.

Mechanical Engineer (2) – The Mechanical Engineers on the project are responsible for the power train system from the electrical motor to the rear drive wheel.  In addition to making the MXB move, the Mechanical Engineers are also responsible for the suspension, rear-breaking and front-wheel steering systems.

Human Factors Engineer (2) – The Human Factors Engineers are responsible for the rider being able to safely mount, ride, stop and dismount the board.  Human Factors Engineers also design the test track and steering obstacles to determine rider and board limits.  Other human factors include an ergonomic handle for control and personal protective equipment.

Computer Scientist (2) – The Computer Scientists design and implement the board’s sensors that include battery charge level, ground speed, and motor temperature.  The diagnostic system uses on-board power to transmit the board’s information to an app that records and displays the test run.

Designer (2) – Designers on the project are responsible for combining the conflicting machine requirements into a single design that accomplishes the machine’s purpose. Additionally, Designers validate the system assembly with CAD illustrations, supervise all component manufacturing, and resolve operational problems that require modifications.

Journalist (1) – The Journalist communicates with the local media and works with the tech groups to produce a final publication. The Journalist also works closely with the Multimedia Artist to provide video and graphic art displays for demonstrations that explain the project to the public. The whole project is your project.

Multimedia Artist (1) – The Artist documents the project’s progress though video records and works with the Journalist to maintain the project’s presence on social media platforms. Additionally, the Artist designs and organizes all public relations events to assure spectator safety and to enhance the community’s awareness of science and technology. The whole project is your project.

Business Manager (1) – The Business Manager reports the project’s progress against a predetermined schedule, determines critical path items to completion, and tracks project spending to assure that costs remain within a fixed budget. The Manager works with all team members to identify problems early and resolve them quickly. The whole project is your project.
