Princeton engineers build motor-free origami robot

Princeton researchers developed a soft-rigid hybrid robot that uses heat-responsive liquid crystal elastomers and embedded flexible PCBs to achieve motor-free movement. By programming molecular orientations and using origami-inspired hinges, the robot can fold and navigate with high precision.

// ANALYSIS

Integrating flexible electronics into 3D-printable elastomers transforms soft robotics from simple actuators into precise, autonomous machines.

–Uses electro-thermal actuation to eliminate bulky mechanical motors and gears
–Embedded temperature sensors enable closed-loop control, a rarity in soft robotics
–Hybrid soft-rigid design with fiberglass panels ensures folding only at programmed origami hinges
–3D-printable LCEs allow for complex, pre-programmed molecular responses to heat
–Open-source design tool lowers the barrier for other researchers to build custom soft robotic systems
