A modular robotic system from EPFL employs surface-based manipulation to address the challenges of handling fragile, deformable, or irregularly shaped objects. Composed of two foldable units each with three degrees of freedom, the system executes fundamental tasks like translation at 5.6 cm/s, rotation at 1.16 °/s, and 180° flipping, and can even manipulate the shape of deformable materials such as putty strips.
Key insights
- Minimalist flat surfaces can effectively perform dexterous manipulation, diverging from traditional grasping and reducing stress on fragile or deformable objects.
- Complex manipulation tasks like translation, rotation, and flipping are achievable with a low minimum mobility requirement (MR_min = 6 DoF for two 3-DoF units) through coordinated bimanual surface interaction.
- The modular and reconfigurable design allows for adaptability to diverse object properties and offers scalability, enabling the potential for shape manipulation of deformable objects.
