Velociraptor Generation #1

Spring 2016 Velociraptor: Project Summary

By: Khoi Vu (Project Manager) Program Objectives & Mission Profile: The Spring 2016 Velociraptor biped was inspired by the robot Titrus-III. The robot that was designed and created by Tokyo Institute of Technology. The purpose of this project is to design a Tyrannosaurus class biped robot to be used as a toy. The mission profile […]

Spring 2016 Velociraptor: Verification & Test Plan

By: Camilla Jensen (System & Test Engineer) In order to verify the level 2 requirements, a verification test plan has been created to test each component for the build of the Velociraptor before incorporating it to the build. The components are tested against its limitations as specified in datasheets and the level 2 requirements and […]

Spring 2016 Velociraptor: Updated Walking Code #3 (Final)

By: Ashlee Chang (E&C) Fulfilling Requirements Level 1 requirements #4 is stated as follows: The Velociraptor shall be able to statically walk on all surfaces of the course. Level 2 requirements #9 is stated as follows: For the Velociraptor to have the ability to travel up a 6.5-degree incline, an accelerometer shall be implemented to preserve the chassis balance. Level 2 requirements […]

Spring 2016 Velociraptor: Updated Block Diagrams

By: Camilla Nelly Jensen (Systems Engineer) According to the Critical Design Review Debrief, the team had made some error in the CDR powerpoint. These errors have been fixed and shown below. For the System Design, the Active Control Circuit for the software blocks of the dynamic walk was missing and thus that circuit has been […]

Spring 2016 Velociraptor: Spring Experiment

By: Mingyu Seo (Manufacturing & Design Engineer) Introduction: After assembling the final prototype and testing the static walk, we’ve found the weight of the head and tail were straining the servos. We’ve decided to use a spring to support the weight, which lead us to perform a quick experiment to see how much the spring will […]

Spring 2016 Velociraptor: 3D Smoothing

By: Mingyu Seo (Manufacturing & Design) Introduction: In order to accommodate mass budget of the robot, our team has decided to create the legs and the top using 3D filament polylactic acid (PLA). One of the drawbacks of using 3D printing method is the result of the prints having ridged surface texture created by the […]

Spring 2016 Velociraptor: Hardware &Simulation

By: Mingyu Seo (Manufacturing &Design) Introduction: The purpose of this blog is to show the feasibility of the design we’re going to incorporate in to our robot. Using Solidworks, we’ll be able to validate center of mass of the robot when we’re performing static walking. Also by using the simulation on Solidworks, it’ll show the […]

Spring 2016 Velociraptor: Critical Design Review Debrief

By: Khoi Vu (Project Manager)   The Critical Design Review (CDR) purpose is to present data and progress of the project to the President and the Customers. The CDR presents the executive summary, system and software design, experimental results, interface definition, and the custom PCB design that will be used on the final product.   […]

Spring 2016 Velociraptor: PCB layout

By: Mingyu Seo (Manufacturing & Design) PCB Design: For our design, we’ve started off by planning where our PCB is going to be mounted. Rather than placing it on top or inside the body frame, we’ve come up with mounting the PCB underneath the body to cover wires connecting all the components together. So, we have […]

Spring 2016 Velociraptor: Material Trade-Off-Study Update

Requirements needed to fulfill: Project Level 1 Requirement: According to the given course that the robot is to complete, the Velociraptor shall travel on multiple surfaces. Refer to course analysis for more detail. The Velociraptor shall be able to statically walk on all surfaces of the course The Velociraptor shall be able to dynamically walk on flat […]
