This is the main introduction video that explains how it works.

"Wow, how did they make a child that tiny? He's walking on a chessboard."
This clip shows a single game being played out. It's a pretty short game, played by a chess master.
Come see it live at
White Chess Pieces
Other locations will be listed here, as arrangements are made.

ChessBot software
· Controls game to Fédération Internationale des Éches (FIDE) rules
· Either color can be human or computer
· Interacts with various third party chess engines using Standard Algebraic Notation (SAN) format
· Currently optimized to work with “Crafty” chess engine
· Save and restore board layout to/from Forsyth-Edwards Notation (FEN) record
· Save and Replay games to/from Portable Game Notation (PGN) file
· Load “Chess Puzzles” for players to solve
· Graphical on-screen helpers highlight available moves
· Battery status of individual chess pieces reported on-screen
· Uses Bluetooth to communicate with individual chess pieces
· Uses an enhanced and customized version of Steve Norris’ original ChessBot


Additional Robot Control Functions
· Calculates robot paths using a recursive square-by-square tree search
· Optimizes the chosen path by assigning point values to…
· the overall length of path
· the number of turns
· the number of border squares used
· the number of occupied squares used
· the ease of moving any blocking pieces
· Automatically clears and restores blocking pieces if necessary
· Parks captured pieces in the border zone of capturing color
· Exchanges promoted pawns for a previously captured piece (where possible)
· Calculates inter-move dependencies to allow multiple pieces to move simultaneously
· Orients parked pieces based on current square and color
· Operates piece-specific functions where appropriate (e.g. knight galloping)
· Automatically resets all pieces to desired position (standard, FEN or off-board)

Nothing but hits
Where are those hits coming from?
