Design and development of a testbench for a robotic bed
Vestibular stimulation induced by rocking beds has been shown to improve sleep architecture and sleep consolidation, shorten sleep onset time, and generate deeper sleep. However, due to the complexity of previous rocking beds, rocking was only applied in lab settings for a few nights only. The Somnomat Casa developed at our lab is a rocking bed for use in private home settings over long periods that provides translational vestibular stimulation in longitudinal direction.
Our most recent Somnomat Casa is already very smooth and comfortable to use. However, we still see potential in improving the actuation of the bed. To arrive at an optimal motor choice, we now want to encapsulate the actuation unit of the bed and compare different motors using various metrics.
The goal of this project is the design and development of a simple testbench that accepts a motor + gear + clutch configuration and records metrics on applied torques, current consumption, smoothness of the motion, noise emission, torque response on dynamic loads, etc.
Your task will be the design and development of a testbench to compare different motor configurations. We have several motor components in the lab that we would like to quantitatively compare. Moreover, you will need to think about metrics that can be used for comparison and conducting preliminary experiments.

You will be working at the Sensory-Motor Systems Lab in a highly motivated environment. You will have access to our modern infrastructure, including a fully equipped electronics lab and machine shop. Also, you will be in close contact with mechanical-, electronic- and software engineers to discuss your ideas.

Ideally, you have an engineering (e.g. in Robotics, System, and Control) background or have worked with motors before. Currently, we are mainly using Maxon motors so if you have worked with EPOS before, this is a plus but not a requirement.
