| In the last century, at the 
						beginning of the eighties, I worked as a gardener for 
						the Siemens Company in Zurich. There I met a lot of 
						technicians and became friends with the deputy manager 
						who maintained good contacts with a subsidiary of 
						Siemens, Video Sonic/Rexton 
			AG. This company represented the company Fidelity Electronics from 
			Miami (USA) in Swiss. They imported several models of their chess 
			computers. The deputy manager of Siemens brought me into contact with the 
			managers of the purchase department who were responsible for the 
			import of the Fidelity chess computers. Because of this, I bought 
			there my first chess computer, a Fidelity Chess Challenger 7.
 
 My 
			interest for chess computers increased, also encouraged by all the 
			good contacts with the employees of Video Sonic/Rexton. Soon, I 
			bought all the available Fidelity computers of that time, and in 
			1980 I discovered that their strongest model was the Chess 
			Challenger Sensory Voice.
 I noticed that Fidelity’s competitor, the 
			company Applied Concepts from Texas (USA), already had come out with 
			a new chess computer, the Sargon 2.5 MGS (Modular Game System) which 
			was at least equally strong as the Sensory Voice.
 Applied Concepts 
			claimed that their Sargon was the strongest chess computer available 
			on the market.
 
 A few days later, at Siemens, I kept my eye on an advertisement in 
			which a colleague offered the Sargon for sale, because the computer 
			was much too strong for him to play with. I didn’t hesitate for a 
			moment and bought his computer immediately. In this way, I came into 
			possession of the two strongest chess computers of that time. 
			Because I was also interested in their new small travel model, the 
			Boris Diplomat, I contacted the importer of Applied Concepts in 
			Zurich, a company called Pool-Tec AG. Some days later, I visited 
			this company.
 I had a chat with one of their representatives and I told him that 
			Fidelity claimed their Sensory Voice as the strongest available 
			chess computer ever made. The representative encouraged me to test 
			the Sensory Voice with the Sargon 2.5 with special positions and 
			tournament games to find out who really spoke the truth about their 
			claims for the strongest computer. After many tests, the Sargon 
			seemed to be the strongest one.
 
 Two years later, in 1982, I visited 
			Pool-Tec again and saw two exactly identical chess robots standing 
			there in a corner, that both had an grasping arm to do their moves 
			completely independently.
 I was totally fascinated and asked the 
			representative if they were for sale. He told me that the two 
			computers were chess robots, named Boris HANDroid and that they were 
			not for sale due to technical reasons. I told the salesman that I 
			would love to buy one of them, in fact I almost begged the man to 
			sell me one of the robots. He told me just to wait for a while, but 
			a few days later, he called me to say that I could come along to 
			collect a Boris HANDroid. Of course, I had my ears wide open and 
			drove to Pool-Tec at once. This is how I became the new owner of 
			this famous and very rare chess robot.
 
 Fortunately, my retired neighbour, Mr. Ernst Rütti, who used to work 
			as a technician at the company NCR, has a lot of electrical and 
			mechanical knowledge. He informed me very well about the working of 
			the robot’s grasping-arm. Once a year he checks the robot and 
			repairs broken parts if necessary.
 He explained to me that the power force of the arm is driven by 
			three so-called Servo engines and special gearwheels which are 
			responsible for the way the robot-arm is moving in a notional X/Y 
			and Z-axis. With these axes the arm is able to move itself correctly 
			forwards, backwards, up and down, to the left and to the right to 
			grab and move the chess pieces.

 Every time you want to play a new game with the robot, the engines 
			and the gearwheels have to turn the arm in the correct angle. The 
			arm vibrates for a long time until the angle has been found. This 
			makes a loud ticking noise, so that it is almost impossible to play 
			chess after 22.00 hours! Maybe the manufacturer could have improved 
			this by making a special switch for it. I think the starting 
			position of the arm could then be found much faster. You can compare 
			it with a printer who brings the ink-cartridges back in the correct 
			position automatically.
 The biggest wear in the arm is a little snare that connects the 
			engines with the mechanism of the arm. Not so long ago, I checked it 
			and noticed that I had to replace it. I know a company in Zurich 
			which is a specialist in selling parts for modelling and I usually 
			buy a new one there.
 If the robot is no longer able to grab the chess pieces correctly, 
			then the problem always lies in the mechanism of the arm. In the arm 
			are two bars which are responsible for lifting the chess pieces up- 
			and downwards. The bars are driven by the engines, the gearwheels 
			and the little snare. After a few games, these bars tend to bend 
			themselves a little and because of this, the HANDroid is not able to 
			grab the pieces properly anymore. Then I have to manually bend the 
			bars back to let it work correctly again. That is a nice job for the 
			real mechanics-lovers, but certainly not for people who are only 
			interested in playing chess with it. I think this is the main reason 
			why the Boris HANDroid never appeared on the market.
 
 The same as his cheaper brother, the Sargon 2.5 MGS, the Boris 
			HANDroid is equipped with the possibility to exchange the program 
			module. This makes it possible to not only play chess with the 
			robot, but also other games like draughts. If a new and stronger 
			module comes on the market, you only have to buy and replace it with 
			the old one. I don’t believe a draughts module ever appeared, 
			because the robot had already too many difficulties playing chess 
			and moving the pieces properly with its arm.
 
 A funny thing to mention is that whenever I win a game, the arm goes 
			forwards and stops above square e1 for a few seconds and then goes 
			back to its starting position. It looks as if the robot wants to 
			shake hands with me...!
 Not so funny is the fact that some time ago, I met the 
			representative of Pool-Tec again, whom I bought one of the two 
			HANDroids from. At this new encounter, I asked the man what happened 
			with the other HANDroid. He told me that one year after our first 
			meeting, he gave the robot to the garbage collector...! I found this 
			incomprehensible but I think he did regret it very much.
 
 Nowadays, I only play a few games a year with the robot. Due to its 
			vulnerability for technical troubles, I think the Boris HANDroid 
			should stay forever in a showcase of a museum. Maybe, some day in 
			the future, I will lend out the robot for an exhibition in the Swiss 
			computer museum.
 
 I’m glad that I was able to tell the Selective Search readers my 
			story of the very rare Boris HANDroid chess robot that should have 
			been the first available robot with grasping arm on the commercial 
			market ever.
 Unfortunately, it never appeared and it has been a 
			mystery for years what happened to the machines.
 Well, I only know 
			there were two of them, because I have seen them myself at the Swiss 
			company Pool-Tec.
 Are there any other units left on this planet?
 I 
			don’t know, but I do hope you have enjoyed my story of the HANDroid 
			of which I’m the proud owner!
