The robot […]

Spring 2017 Velociraptor: Counting the Number of Dots Encountered

Authors By:  Oscar Ramirez (Mission, Systems, & Test) -Body Edited and Approved By: Jesus Enriquez (Project Manager) -Introduction & Conclusion Introduction One of the other challenges that we faced on top of choosing and configuring a color sensor was the challenge of interfacing the Arxterra app custom telemetry with the count dots command. This post […]

Spring 2017 Velociraptor: Custom Commands (Servo Motor)

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 issue we decided […]

Spring 2017 Velociraptor: Schematic, PCB, and Construction

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 the PCB was […]

Spring 2017 Velociraptor: Final Assembly Update

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 and tail were […]

Spring 2017 Velociraptor: Configuring the TCS34725 Color Sensor

Authors By: Oscar Ramirez (MST) -Body Edited and Approved By: Jesus Enriquez (Project Manager) -Introduction & Conclusion Introduction One of the requirements for our Velociraptor was giving it the ability to count the number of dots it encounters in the maze. In order to solve this issue, we came up with a creative solution which […]

Spring 2017 Velociraptor: Configuring the HM-10 to Work With the TB6612FNG

Authors By: Oscar Ramirez (MST) -Body Edited and Approved By: Jesus Enriquez (Project Manager) – Introduction & Conclusion Introduction One of the challenges that we had to come up with was coming up with creative way to get the Velociraptor to perform a static walk. Adding to this challenge we needed to control and implement […]

Spring 2017 Velociraptor: Robot Assembly Process

Authors By: Andrea Lamore (Manufacturing) – Assembly Process Edited & Approved By: Jesus Enriquez (Project Manager) – Introduction & Conclusion Introduction Before going into Critical Design Review, our team had to assemble the Velociraptor in order to have it Demo ready. Prior to PDR, we had a design in mind which was modeled on SolidWorks which […]

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 […]
