SpiderBot Generation #4

Fall 2015 Final Project Document: Boris the Spider-Bot

By: Sean McGee (Project Manager) The Fall 2015 Spider-Bot team consisted of: Sean McGee (Project Manager) Paul Schlosser (Missions, Systems, and Test Division) Matthew Kedis (Electronics and Control Division) Dakota Jones (Manufacturing Division) 1. Executive Summary The purpose of this project is to create a six-leg’ed robot that can be controlled remotely using the Arxterra […]

Servo Trade Off Study

By: Sean McGee (Project Manager)        Paul Schlosser (Systems Engineer)        Matthew Kedis (Electronics and Control) To conduct our servo trade off study, we hooked up our servo controller to one servo and placed a current meter in series with the positive side of the power into the servo driver. We […]

Boris: The Complete 3D Model

By: Dakota Jones I was able to assemble together all the SOLIDWORKS parts to make a 3D model of Boris. The model of Boris shows how we will be mounting our servos to the top body plate. It also shows how our brackets connect the top body plate to the bottom body plate. These brackets also […]

Final Body Design

By: Dakota Jones (Manufacturing Division) The legs and body design was determined by first looking at what design would work best for our mission profile. We needed to be fast and lightweight, yet durable. Those three guidelines guided nearly every decision we made in the overall design of the legs and body. These guidelines first helped […]

Surface Mountable Printed Circuit Board Design

By: Matthew Kedis (Electronics and Controls) and Dakota Jones (Manufacturing) After creating our simplified PCB and determining that it worked, we then moved on to spec out a finalized PCB that would use surface mountable parts. Figure 1 Figure 1 shows our entire system for our Spiderbot that will be layed out on the PCB. This […]

Manufacturing Boris the Spider

By: Matthew Kedis (Electronics & Controls) and Sean McGee (Project Manager) Our Spiderbot was manufactured out of 6061 Aluminum through CNC machines thanks to Viper Technologies in Torrance. Figure 1 Figure 1 shows the bottom of our Spider-bot being ready to cut out the pockets in the machine. This piece took quite some time due to our […]

Using the Arxterra App

By Paul Schlosser (Systems Engineer)  Now that we know how to program a walking motion, it’s time to use that new knowledge with the Arxterra firmware to be able to use the RC mode of the Arxterra App.  The main command we are looking for is the move command. This sends the data to a […]

Using Data Structures and Lookup Tables for Servo Motion

By Paul Schlosser (Systems Engineer) We learned earlier that servos move by sending them a PWM signal that will correspond to a degree of motion between 0-180 degrees.  The physical setup of our spider had 2 servos per leg.  One servo controlled up and down motion while the other controlled left and right motion.  The […]

Simplified PCB Layout

By: Matthew Kedis (Electronics and Controls) We decided to go with a surface mountable PCB board for our final product, however we created a PCB that has all of our features that we want with headers. We decided to go with two different PCB layouts for two main reasons. First, we wanted to have some practice with […]

Switching to the Arduino Uno

By: Paul Schlosser (Systems Division)   After talking with the President and Vice President, we determined that the Arduino Uno would have sufficient storage space to run the software necessary. Because of this, we chose to replace our Arduino Mega with the Uno.   Wiring Changes: Making the change was fairly trivial. For the wiring, […]
