Integrated System Build & Test

Table of Contents

Phase 3 Overview

Throughout the course of this phase the team was able to build and test all individual subsystems and components required for the whole system build. After testing, the full system was assembled and there were key attributes that require attention in order to proceed with the intended goal of measuring cable tensions at particular points throughout the build volume. In addition to the system build, the team was also able to reach the deliverables for this phase as shown below.

Problems

Electrical

Throughout the testing of subsystems there was a concern on the amount of current draw the motors would have and the impact that it would have on the motorsheild and the Arduino. Observation show that there was only a 0.3A current draw across all three motors, despite these motors having the ability to draw up to a maximum of 4.2A.

There was an issue that was preventing us from allowing these motors to draw more current for motor torque.

Top down approach was taken.

1. Observe all wiring.
2. Reference wiring schematic
3. Review of Arduino Motor Shield
