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
