Spring 2017 SpiderBot – DC Motor Noise Experiment

By Nicholas Jacobs – Project Manager By Shaun Pazos – E & C Problem Bluetooth wireless communication is subject to massive amounts of interference because of the high-volume traffic on the 2.4 GHz frequency band, and is also subject to the noise generated by DC motor voltage spikes from each commutator as the shaft turns. This […]

Sping 2017- SpiderBot’s Cost of Learning

    By Nicholas Jacobs – Project Manager   As the Preliminary Design Review approached, Daniel, our Manufacturing Engineer, diligently modeled all of SpiderBot’s pieces in SolidWorks. SpiderBot’s design, originally found at Instructables. com, came with .dwg CAD files that had to be converted into .dfx files, which act as the industry standard for laser printing. […]

Spring 2017 – Spiderbot – Torque Test

  Torque Testing By: Shaun Pasoz Electronics & Control Engineer   Torque testing allows the designer to see if a desired motor can output enough force to physically move a robot. To perform the test, a rig was designed in which the motor was clamped down with a fixed radius on the output shaft. Varying […]
