1. INTRODUCTION

   Chess is a two-player strategy board game played on a chessboard, a checkered game board with 64 squares arranged in an 8×8 grid. The game is played by millions of

   People worldwide. Chess is believed to have originated in India sometime before the 7th century.

   Though the game is complex one, it is based on approaching, threatening and capturing pieces until destination is reached. John Artise in Chess and Education states: Visual stimuli tend to improve memory more than any other stimuli; chess is definitely an excellent memory exerciser the effects of which are transferable to other subjects where memory is necessary.

   The classic game has come a long way from ancient times to modern days but yet remains a mind boggling challenge of intense strategic play and patience. Its endless no. of

   permutations and combinations is what makes it so interesting every time a new game is played

   Artificial intelligence is booming branch in technology which can be simply defined as Any device /software that perceives its environment and takes actions that maximize its chance of successfully achieving its goals which is often compared to the "cognitive" functions that humans associate with human minds, such as "learning" and "problem solving".

   In recent years AI is successfully associated with applications such as understanding human speech, competing at the highest level in strategic game systems (such as chess and Go),autonomously operating cars, and intelligent routing in content delivery networks and military simulations.

   The project aims to combine both these entities to create a self- playing chess board which has the capacity to stand on its own as a playing unit for a single person without any opponent.

   The pieces on the board will automatically be moved on the board according to AI to as the device will try to beat the person in front and thus create an unparalleled experience for a chess player.

   As the world gets more and more technology oriented use of devices such as cell phones

   Laptops etc. is on the rise. This result in excessive screen time which results in irreversible damages to eye site .the effect is even worse in children. Thus the project provides a real chess partner instead of a virtual experience

   The experience between the virtually available chess and the real chess playing experience is immense and not matched in the virtual world. The project provides a professional chess player with a simple training companion where he can train as long as he /she wants it uses powerful processors such an Arduino mega and Raspberry pi3 along with a Stockfish engine. The Arm motion is carried out by 2 stepper motor with 1200steps/rev as the base joint. Then there are 1 servo motors which are light weight yet effective at the Z Axis use for pieces Pick and Place.

   The reed switches are magnetically switching devices which are used to detect human moves and thus send information about the human moves. Forward and reverse kinematics will be used to easily provide accurate precise and simple motion of the robotic Frame.

   Thus the project provide the real chess playing experience using modern technological tools and artificial intelligence.

2. METHOD

   THE H-BOT CONCEPT

   This H-Bot concept represents the interaction of

   Two rotary drives which are connected by a Single H-shaped circumferential timing belt around two staggered linear axes in a gantry type like configuration, see figure 1. The kinematics of the H-Bot mechanism formulated in (1), where x and y are the TCP- and q1 and q2 are the drive-coordinates in radians is the drives pulleys radius. Due to the fact that the drives do not have to be moved the achievable dynamic values can be quite high. Another aspect of this concept in contrast to delta-robot like kinematics is that the weight of the work load is carried by the linear guide ways and not by the drives. Also, the working envelope, the required transformations and the uniformity of the distribution of properties are far easier to handle for industrial use than the often odd shaped working envelopes, complex kinematics and the strongly nonlinear property distribution of alternative

   concepts

   and the kinematic [3], numbering of bodies

   The reed switch matrix

   64 reed switches are needed to build a 8×8 matrix. There's a big difference with a micro switch matrix as used. Any square containing a piece will have its reed switch activated. In a matrix like this can occur "ghost" activations, i.e., when the microcontroller scans the matrix it "can think" that there are some switches activated when in fact they are not. This effect, known as "ghost key", is solved by adding a diode in series with each of the switches.

3. MEASUREMENT RESULTS

   On a first prototype a series of measurements covering geometric properties could be carried out.

   Figure 2 shows exemplarily the results of a circle test. As opposed to measurements on serial axis concepts the systematic deviations show additional systematic effects: At axis reversal similar effects are noticed as are typical for axis having semi-closed position feed-back. In addition to these at the axes reversals similar affects are visible at positions on the

   ±45° diagonals. These effects are caused by drive reversal, where station occurs on the driven pulley and/or motor bearing in combination with backash of the belt. Based on these first measurements on the prototype, a number of improvements could be achieved using feed forward torque computation. By this effects of friction and inertia could strongly be reduced as can be seen in Figure 3.

   Especially the effects on the ±45 locations could be reduced significantly. For pick and place applications that the robot is designed for, position accuracy is only important at the end of a motion. In Figure 4 the results of a positioning measurement according to ISO 230-2 are shown. As can be seen, a quite good repeatability is obtained, when regarding unidirectional approach of measuring positions. The reversals are quite large and slightly position dependent. The position deviations show

   a systematic slope, which could be reduced, when applying linear pitch error compensation.

5. RESULTS

   Fig No. 5

   • A working model of the Chess Board

   • To make it easier for players not only to play the game of chess but also to learn new techniques

   • The game shouldnt be player centric, it should be as much applicable to a beginner as to a professional

   • The movement of the pieces should be natural and not mechanical

   • The player should have a sense of playing a human and not a machine

6. DISCUSSION AND CONCLUSION

   1. The Advancements in technology havent entered the game as of now .The physical chess playing experience is not matched in the digital world

   2. Thus the project will help to bridge this gap and provide a hassle free experience for a human to play against a AI based system

   3. Its time to move back from a virtual world to the real world. And not just moving back but taking the best out of both the worlds. In this project me make use of AI to help our mind be better at critical thinking. It is supposed to serve as a tool to the mind.
