Fun! actual robotic arms should have any kind of sensor, but it is a nice starting point

In the review of the robot arm, they said the motors were not accurate enough to do something useful with it... but still fun to see that people still use it 30 years later in a school! Smile

Loading error free from a tape 30 years later is already an applause worth.

Indeed... The actual movement of the arm depends of how much juice there is left on the batteries, but it is what it is. The best use I've found for this is to play Pong against it... When you give it a joystick, then you have your sensors ;-)

If I would like to control a robot today on MSX I would use servo motors instead. The bad thing is that you need to know the starting position of the robot (unless you want to make it jump recklessly) but servos anyway allow very accurate movement. I've actually made a little BASIC-library that allows you to hook up to 8-servos directly to printer port and then drive them with 8-bit accuracy on background... it allows you to easily do all kind of cool stuff with your MSX without need for anything else but bunch of wires and power source to run the servos. :)
