Michael’s Tower of Hanoi Robot
This is the model that started it all. The small robot is activated by three stepper motors plus an electromagnet. All are controlled by the Code7 Stepper Motor controller. One motor controls base rotation, a second moves the shoulder joint and a third the forearm. Because of the wrist body linkage – the hand is always parallel with the table top. Any one of the motors, or all of them at the same time, can be activated and a sequence of positions reached. Switching the electromagnet on and off is achieved through the program and the interface. In this way the robot can do a job of work. Once the positions have been taught, the program can be run and all the positions reached in automatic sequence. Any errors can be corrected or edited.

The crane has three stepper motors, one for base rotation, one for jib luffing and the third for the load. The gearing from the motors has been chosen to obtain a reasonable output speed while avoiding motor torque overload. The motors have been connected to the electronic interface board which has its own power supply and is connected to a computer. The program which drives the model is the Code7 Stepper Controller. By clicking on the computer screen icons or buttons the three motors can be taught a sequence of positions in which each motor moves individually or two or more motors move simultaneously. The sequence can then be run in a continuous loop (File size 13MB).
The Ferris Wheel
Luis Lanca is sharing with us his Ferris wheel project, this is his description of the work. There are 8 cars in my Ferris Wheel Meccano Project; each individual car (from 1 to 8) will stop at loading platform for a few seconds to get the passengers and then it will do a full revolution. Once the full revolution is complete, each individual car will stop again to unload / load the passengers. (File size 39MB).
