Velociraptor (W)

Spring 2017 Velociraptor: First SolidWorks Model

Authors By: Andrea Lamore (Manufacturing) Approved By: Jesus Enriquez (Project Manager) Introduction During the early stages of the design process, leading up to PDR, the Velociraptor’s frame was similar to what was presented at CDR but had a few distinct differences in terms of specific part modification and part sizes. The purpose of this post is […]

Spring 2017 Velociraptor: DC Motor Selection

Authors By: Mohammar Mairena (Electronics & Control) Approved By: Jesus Enriquez (Project Manager) Introduction Through research on DC Motors, I came across gear motors. Gear motors add mechanical gears (gearbox) to reduce speed/increase torque and vice-versa. The increase in torque is inversely proportional to the reduction in speed. Each gearmotor has a different gear ratio […]

Spring 2017 Velociraptor: Fritzing Diagram

Authors By: Mohammar Mairena (Electronics & Control Engineer) Approved By: Jesus Enriquez (Project Manager) Introduction Before one can create a custom printed circuit board (PCB), one has to create a Fritzing diagram. A Fritzing diagram is a virtual electronic circuit that is modeled after a circuit tested on the breadboard. Fritzing is used to provide […]

Spring 2017 Velociraptor: RGB Color Sensor

Authors By: Mohammar Mairena Approved By: Jesus Enriquez Introduction The Velociraptor will compete in a game similar to Pacman. One of the requirements is that the Velociraptor shall attempt to collect as many red dots as possible while navigating the maze utilizing either a static or dynamic walk. As a result, we will be using […]

Spring 2017 Velociraptor: SolidWorks Hardware Design Model

Authors By: Andrea Lamore (Manufacturing) Approved By: Jesus Enriquez (Project Manager) Introduction Throughout the engineering design process, the SolidWorks model for the Velociraptor went through a series of changes as our team went through trial and error with the different components for the robot. This post includes some of the thinking that went behind the […]

Spring 2017 Velociraptor: Servo Torque Test

Authors By: Mohammar Mairena, Electronics & Control Engineer Approved by: Jesus Enriquez, Project Manager Introduction The torque needed to move the different parts of the robot are specified by the Design and Manufacturing engineer. By testing the torque required at a specific location of the robot, one can prove the servo chosen will handle the […]

Spring 2017 Velociraptor: Range of Motion Prototype

By: Andrea Lamore (Manufacturing) Approved By: Jesus Enriquez (Project Manager) Introduction The range of motion of the leg determines the type of step the robot will take. A static walk requires a different stride from a dynamic walk and it is important to pick the linkages in the leg according to the type of walk […]

Spring 2017 Velociraptor Preliminary Project Plan

Project Team: Jesus Enriquez (Project Manager) Oscar Ramirez (Mission, Systems, & Test) Mohammar Mairena (Electronics & Control) Andrea Lamore (Manufacturing) Work Breakdown Structure By Jesus Enriquez (Project Manager) The figure below shows the Work Breakdown Structure for the Velociraptor project splitting the responsibilities and tasks of each member within their respective division. The structure was […]

Spring 2017 Velociraptor Preliminary Design Documentation

Velociraptor Team: Jesus Enriquez (Project Manager) Oscar Ramirez (Mission, Systems, & Test) Mohammar Mairena (Electronics & Control) Andrea Lamore (Manufacturing) Program Objective/Mission Profile By Jesus Enriquez (Project Manager) The Velociraptor Biped, inspired by that of the Titrus-III model developed by the Tokyo Institute of Technology, is to meet customer expectation through demonstration in a negotiated […]

Fall 2016 Velociraptor (W): Final Project Document

By Lam Nguyen (Project Manager) Executive Summary of Project Project Objectives For CSULB Fall 2016 semester, the Velociraptor biped robot project will branch off to a new species of dinosaurs and set up a new baseline with the Theo Jansen robot design. The Velociraptor is to be a toy robot resembling a Theropodous dinosuar suborder […]
