Internship: Robot-Assisted Toothbrush IMU Validation at Philips in Eindhoven

Job Title Internship: Robot-Assisted Toothbrush IMU Validation Job Description Start Date: January/February 2027 Duration: minimum 6 months Type: Internship Weekly Presence: 40h (minimum 32h) Location: Eindhoven Internship: Robot-Assisted Toothbrush IMU Validation Different toothbrushes use inertial measurement units (IMUs) to characterise brushing motion. To compare their measurements fairly, each brush should undergo the same physical motion. In this assignment, you will develop a repeatable test bench combining a 6-DOF robot arm (SeeedStudio reBot Arm B601-RS), OptiTrack motion capture system and toothbrush IMU sensors. Human brushing trajectories, recorded at 120 Hz as position and orientation data, will be transformed into safe robot trajectories and replayed. OptiTrack will independently measure the reproduced motion, enabling quantitative comparison of robot accuracy, repeatability and IMU responses across toothbrushes. Your challenge: Build and validate a measurement protocol that separates true motion differences from sensor effects such as axis conventions, offset, scale, noise, filtering and timing. Your team: You will work in the R&D department of Philips Oral Healthcare in Eindhoven, alongside experts in sensors, data science, robotics and oral healthcare. The project combines hands-on experimentation, software development and quantitative signal…
