ICRA-2010 and AAAI-2010 Small-Scale Manipulation Challenge: Table top Chess

Overview

The ICRA-2010 and AAAI-2010 Small-Scale Manipulation Challenge is designed to highlight advances in embodied intelligence using smaller than human size robots. Robotic chess requires the integration of sensing, planning and actuation and provides an opportunity for performance on a common, well-defined task.

As a new challenge, the inaugural year will focus on enabling teams to participate at many levels of autonomy and environmental constraints. The long-term goal is to gauge performance of mobile manipulation approaches in arbitrary environments under identical constraints.

Changes and updates to the challenge criteria will appear on this page.

Participation in either ICRA or AAAI challenges

ICRA Letter of Intent due: Jan 1, 2010
AAAI Letter of Intent due: February 1, 2010


- Send a letter of intent that includes the team name and the names of the team members and the email/phone number of designed contact person to anderson@cs.ua.edu and dst@cs.cmu.edu

AAAI Qualification due: April 1, 2010

Robot teams are required to submit a 2-page abstract providing a summary of their approach along with creating a short video of their robot that demonstrates basic navigation and obstacle avoidance capabilities. This will ensure that the robots have the basic capabilities to explore the competition environment safely. Email to anderson@cs.ua.edu and dst@cs.cmu.edu



1. Qualifying round playing criteria

Board Setup
- Chess board and chess piece colors may be determined by each competitor
- Play with non-standard board (standard 2.25in or slightly larger 2.75in squares)
- Board will have a contrasting color border around it that separates
the board edge from the table
- Standard chess pieces (recommend Staunton standard tournament pieces No 5 - available at Amazon)
- Board with 5in squares with chess pieces in starting positions
- 5 inch neutral play area around board of infinite height (no
positioning above board when not in play)
- Robot can be placed anywhere outside of play area at beginning of move
- Well-lit but arbitrary lighting
- Colors and first move chosen by coin toss

Robot criteria
- No size limitation
- Can be controlled off-board (secondary computer)
- May utilize a persistent power source (but cannot disturb pieces on board)
- Must accept game play state via a network signal (to be defined) -
States are Ready - Beginning Sync state that allows each robot to survey the board and reset data structures , Go-period during which board move is made , Opponent-opponenet is making its move, Done-the game is complete
- No other user input may be incorporated

Playing criteria
- 2 minutes to make move and clear play area without penalty; five
minutes results in forfeit of move and manual removal of robot
- A game is 10 legal moves on each side (in the interest of time)
- X number of forfeited moves forfeits the game
- Pieces must be placed completely within a legal square, and no other piece may be left in an illegal position. Violations may be corrected by a human referee with a point penalty.

Scoring (Tentative)

Winner of this level has the highest score. Scoring criteria include:

150 points for each successful move within time allotment
10 deduction for each piece that must be repositioned by referee
25 points for each piece captured

Extra points are awarded for the following features:

Game states:
- Pieces start out in a random pile and the robot places them on the board
- Pieces are standing but otherwise randomly arranged, and the robot
places them on the board
- Board starts out in an arbitrary mid-game configuration (so vision
must be used to recognize piece shapes)

Error recovery:
- Robot notices if a piece is knocked over, and picks it up
- Robot notices if a piece is knocked over, and asks for help

Verbal Commentary:
- Robot delivers running commentary on the game
- Robot only announces its moves, captures and win/lose
