Scribble is an Arduino-controlled haptic drawing robot
As part of his master’s studies at Eindhoven University, Felix Ros created a haptic drawing interface that uses a five-bar linkage system to not only take input from one’s finger, but also act as a feedback device via a pair of rotary outputs.
“Scribble” uses an Arduino Due to communicate with a computer, running software written in OpenFrameworks.
For over a century we have been driving cars, enabling us to roam our surroundings with little effort. Now with the introduction of automated driving, machines will become our chauffeurs. But how about getting us around a road construction, or finding a friend in a crowded area? Or what if you just want to explore and find new places, will these cars be able to handle such situations and how can you show your intentions?
Currently there is no middle ground between the car taking the wheel or its driver, this is where Scribble comes in: a haptic interface that lets you draw your way through traffic. You draw a path and the car will follow, not letting you drive but pilot the car. Scribble lets you help your car when in need, and wander your surroundings once again.
You can learn more about Ros’ design in his write-up here, including the code needed to calculate and output forward kinematics to set the X/Y position, and inverse kinematics to sense user input.
