Versions

Candi (V1.0)

At Competition

Mechanical Issues & Improvements

Current design of Candi Frame


Old BattleBots motors. A new frame is currently being fabricated from 1" square tubing. New body will have front suspension and a giant ball caster in the rear.

Electrical Issues & Improvements

A map of Candi's systems.

Software Issues & Improvements

PlayerStage

Candi's process diagram.

Code from Graduate Students - Restricted access (must be logged in to access)

Candii (V2.0)

At Competition

Mechanical Issues & Improvements

Electrical Issues & Improvements

Diagram showing the flow of data between the various robot controller components

Needs correction:

  • GPS communicates over COM2(/dev/ttyS1)
  • Time server (NTP) runs on the TS board reading the Data Carrier Detect (DCD) line of COM2
  • Add: TS Board is running an NTP server to define robot time
  • Software modules should be included
  • Rename "Arduino" -> "Motor Arduino"
  • Add "Power Arduino"
  • Fix: Wheel Encoders will be communicating over SPI

Software Issues & Improvements

Our code for this year is stored in Subversion and is accessible at https://svn.robojackets.org/igvc/2008. The laptop codebase will be written in C++.

Contributers to the laptop codebase should ensure that they are following our coding conventions.

Player/Stage:

We are using the Player/Stage robot server as the communication layer between our device drivers and our processing/controlling software modules.

As we've used the Player server, occasionally we've needed to patch it to better suit our needs. Below are our custom patches:

Candiii (V3.0)

At Competition

Mechanical Issues & Improvements

Candiii's body has remained essentially the same for the last 2 years.

Electrical Issues & Improvements

Candiii has two isolated power systems: one for the motors and one for the other electronics.

Other Electronics:

  • Camera
  • LIDAR
  • IMU
  • GPS
  • Compass
  • Motor encoders
  • Motor currents

Software Issues & Improvements

Localization and Mapping:

Controls:

  • PI-Lead control(?)
  • Joystick
