Web Page for Control

Webpage served to user for control. This webpage is hosted on the Raspberry Pi, and will forward commands to the arduino.

• Joystick for motor control and movement. (Options for alternative WASD control, as it may be easier)
• Buttons which control the actions performed by the robot.
  • Latching (Engage and Disengage)
  • Pulley (Pull and Release)
  • Loading

Difference from Initial Design

• Originally, we planned to use an arduino Wifi module. While this would have worked, we decided to use a raspberry pi as a webserver because it enabled flexibility, cross-compatibility, and easy debugging.
• We use simple buttons as triggers which just starts some control sequence, except for movement. This makes timing actions irrelevant as any time-sensitive actions are taken care of locally on the Arduino.
