Design Changes  We will not assemble a complete ROBOT  ME Team Switched to a PAPER design  We designed the EE subsystem  We are building and testing the EE subsystem only Presented By Nasser Almarri

Visual basic GUI Presented By Nasser Almarri

Prototype Testing  PC Interface w/ Controller  VB GUI  Text file - Yterm2000 Encoder Position  Data Collection  Direct w/ Controller  PC Interface w/ Launch Monitor  VB GUI  Raw data files Presented by John Boring

Launch Monitor  Works with Golf Achiever software  Connects with computer by serial port cable  Outputs velocity and launch angle  Used to optimize a golfer’s clubs Presented by John Boring

Software Interfacing  Visual Basic GUI  Two separate software  Yterm2000  Golf Achiever  One PC will be used  Multiple Connections  Shared GUI Presented by John Boring

Potential Problem & Solution  Multiple Hardware  Port / connection problem  Controller  Ethernet connection  Launch Monitor  Serial port connection Presented by John Boring

Integrating the Monitor & the GUI Methods to use Golf Achiever Software  Capitalize on Raw Data functions  Open Raw Data File  Save Raw Data File  Open those files from inside VB GUI Presented by John Boring

Monitoring Elbow Position  Presented by Charles Siko

Background on Encoders  Used to determine position  Many types Linear/Rotary Absolute: each position is unique Incremental: position is relative Magnetic: durable, lower resolution Optical: high resolution, high speed Presented by Charles Siko

Absolute Encoders  Singleturn- 360° is divided into digital values  Multiturn-in addition to the coded disk this includes an integrated gear which can count multiple revolutions  Typical Outputs Presented by Charles Siko

Choice 1: BEI optical absolute encoder $680.00

Choice 2: Netzerprecision electrical absolute encoder Presented by Charles Siko $75.00**
