MobiLimb is a robotic finger that plugs into your smartphone

Arduino TeamOctober 2nd, 2018

You’re constantly poking and prodding your smartphone throughout the day, but have you ever wondered what would happen if this little computer could poke back? Well now that’s actually possible, with the MobiLimb accessory by Marc Teyssier and a team stretching across two universities in France.

The device uses an Arduino to interface with the phone or other smart device via its micro USB port, and powers a servo-actuated robotic manipulator with five degrees of freedom. The servos give the artificial finger enough power to pull the phone itself across the ground, and for other interactions like acting as a physical avatar, propping the phone up as a stand, or even taking input as a joystick apparatus.

MobiLimb is a new shape-changing component with a compact form factor that can be deployed on mobile devices. It is a small 5 DoF serial robotic manipulator that can be easily added to (or removed from) existing mobile devices (smartphone, tablet). In the spirit of human augmentation, which aims at overcoming human body limitations by using robotic devices, our approach aims at overcoming mobile device limitations (static, passive, motionless) by using a robotic limb.

This approach preserves the form factor of mobile devices and the efficiency of their I/O capabilities while introducing new ones:

  • The users can manipulate and deform the robotic device (input)
  • They can see and feel it (visual and haptic feedback), including when its shape is dynamically modified by the mobile device.
  • As a robotic manipulator, it can support additional modular elements (LED, shells, proximity sensors).

More info is available in Teyssier’s write-up, and you can see it in action in the video below.
