Mechanics of CONAPP. CONAPP means Controller Application. There was need for a task the Transputers had to do. The most complicated machine to be build by a hobbyist is something like a "Robot". Whatever that may be; in this case a kind of vehicle running on the floor and only controlled by itself. The design considerations were: build a vehicle that is very good in manoeuvrability and very, very sturdy. So the frame is of 3 mm aluminium strengthened with profiles to mount the batteries and more on it. The front wheels are independent steerable and the rear-wheels are mounted on a platform that is turnable against the frame. Each rear-wheel has his own motor so that is a way to steer too because when the rotational speed of both wheels are not the same, the construction they are mounted on is turning and so the entire vehicle does. The hood of an analytical balance is used and some motors plus gearboxes that were very good for the purposes from other instruments. Plus that there was some mechanical material that was useful. And important too, it was possible to use some machines in an instruments workshop so the vehicle got the appearance shown below.
But why have all wheels the task to steer? Well, the idea is that CONAPP will be able to do tricks that are not yet shown before. More on that later. And, did you ever see a "robot" that has a hood? All wires, circuits and so on are covered.
