Lego-like mechanical blocks let robots reprogram stiffness and swimming paths
SMRTR summary
Duke University engineers created Lego-like blocks that can reprogram their mechanical properties by switching internal cells between solid and liquid states using heat. When assembled into robotic fish tails, the same blocks produced completely different swimming patterns based solely on which internal cells were liquified, demonstrating programmable materials that change behavior without changing shape.
