By: Ashlee Chang (E&C) Table of Contents 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 #10 is stated as follows: An ultrasonic sensor shall be implemented to the build of the robot to detect obstacles at a range of 20 cm. […]
By: Ashlee Chang (E&C) Table of Contents A Clean Electronic Setup Breadboard testing The electronics journey goes as so: Fritzing diagram, breadboard testing, circuit schematic, and then PCB (printed circuit board) fabrication. All electronic components are Arduino microcontroller, four batteries, eight servos, Bluetooth, ultrasonic sensor, and accelerometer. Notably, there are quite a bit of components, […]
By: Mingyu Seo (M&D) Introduction: Humans use center of mass to balance, for example when we are standing on both feet our center of mass would be at the center of our body, but when we try to position or balance on one foot, we shift our body closer to the supporting leg which also […]
By : Camilla Nelly Jensen (Systems Engineer) In order to meet the project level 2 requirement 13 for the Velociraptor, the Bluetooth module shall be connected to the microcontroller to establish a wireless communication with the Arxterra application that is installed on an android device. Below are the instructions on how to establish this communication. […]
By: Camilla Nelly Jensen (System Engineer) Requirements: 6. To maintain balance while performing static walking, a head and tail shall be implemented to the chassis of the Velociraptor to even out the shifted weight when standing on one leg and thus meet the Project Level 1, requirement 4. Figure 1: http://design.tutsplus.com/articles/human-anatomy-fundamentals-balance-and-movement–vector-20936 Verification [6]: Figure 1 shows, the […]
By Ashlee Chang (E&C) Table of Contents Fulfilling Requirements Level 1 requirements #4 is stated as follows: The Velociraptor shall be able to statically walk on all surfaces of the course. The Arduino software, which uses much of C++ programming language, will be used to construct and upload the code onto the Arduino microcontroller. Coding Summary This blog […]
By: Camilla Nelly Jensen (System Engineer) Table 1: Comparing the Microcontrollers Table 1 compares two possible microcontrollers which acts as the brain for the Velociraptor. The microcontrollers will be used to connect all the components required for the Velociraptor. The chart compares pins available, input voltage, dimension, weight, memory, and average price. The amount of pins necessary for the […]
By Ashlee Chang (E&C) Updated: 03/30/16 Table of Contents Fulfilling Requirements Level 2 requirements #7 is stated as follows: 7. For the Velociraptor to perform dynamic walking servos moving at a speed of 0.101 sec/10° shall be implemented to the chassis and thus meet the Project Level 1, requirement 5. The servos will be the motor […]
By: Ashlee Chang (E&C) Updated: 04/05/16 Table of Contents Fulfilling the Requirements Level 2 requirements #9 and #10 are stated as follows: 9. For the Velociraptor to have the ability to travel up a 6.5-degree incline, a gyroscope/accelerometer shall be implemented to preserve the chassis balance and thus meeting the Project Level 1, requirement 6. […]
By Mingyu Seo (Manufacturing & Design) Approved by Khoi Vu (Project Manger) For the Velociraptor Project, we have considered several materials for manufacturing prototypes as well as for our final robot. The chart shows advantages and disadvantages of the material, to help us consider the different materials we’ll use for the velociraptor: Through careful consideration, […]
