Table of Contents Authors By: Oscar Ramirez (Mission, Systems, & Test) -Body Edited and Approved By: Jesus Enriquez (Project Manager) -Introduction & Conclusion Introduction One of the bug requirements that we needed to satisfy for our Velociraptor was giving it the ability to perform a turn in order to navigate the maze. To solve this […]
Table of Contents Authors By: Andrea Lamore (Manufacturing) Edited & Approved By: Jesus Enriquez (Project Manager) Introduction We had to build a custom PCB. Our PCB contained a 12 channel PWM expander the communicated with the peripheral devices that the 3Dot board did not have pinouts to hold. It was important to make sure everything on […]
Table of Contents Authors By: Andrea Lamore (Manufacturing) Approved By: Jesus Enriquez (Project Manager) Introduction Assembly of the first velociraptor demonstrated some problems that were not clear from the SolidWorks model alone. These problems included a wobbliness/loose motion of the legs, the hip joint was arching when it should have been straight, and the head […]
