As mentioned here, here's what I am currently thinking doing. - side 'back' wheels would drive in one direction - side 'front' wheels would drive in the opposite direction - side wheel would have to move towards the sharpie to produce the required friction to allows the 2 pieces to be move apart. ...

Color'er - update 2

In my first update, I've mentionned that 3 forces were needed. Obviously, I can't really use 3 actuators (1 motor and 2 linear actuators or 3 motors...), that would be overkill for such a device. Ideally, a single motor would have to be able to deliver those 3 forces but time is running so I'll work a simpler solution for now that we'll be using using 2 actuators (2 motors including the one from the kit). If it works and if I still have time, I'll see if that can be improved.   I have star ...

Color'er - update 1

While waiting for the kit to arrive, I've started to think about the mechanical aspects of the challenge.   Simple acts are sometime difficult to model as they're so simple that we don't really think how we perform them. The action of taking a cap off involve 3 forces (A, B & C), A & B are used to hold the 2 parts (sharpie & cap) and need to be performed at the same time while the third force (C) will take them apart and should be performed after A & B (while A & B are ...
It is only when you are directly impacted that you can realize that very simple daily acts are sometime virtually impossible to realize for people with disabilities.   I realized that when my young daughter, who is suffering from a neuromuscular disorder, started to draw. She had enough strength to draw but not enough strength to take caps of from her sharpie markers. This quickly became a source of frustration for her.   People suffering from neuromuscular disorders (e.g. SMA) have ve ...
