Manufacturing process and LMPA disposal process of the self-healing module. A) Liquid metal pouring. We poured the liquid metal into half of a self-healing module. The liquid metal had been melted in the stainless cup with a soldering iron. The photos show the half module with an empty state and the one filled with LMPA. B) Module assembly. First, we combined the half modules filled with LMPA using the magnetic force. Second, we attached the rubber bands to the module assembly. Third, we heated the inner LMPA component using the heaters. Actually, The third process is identical to the temperature control of the self-healing sequence. C) After being engaged in a robot, the module’s LMPA was recycled. We melt the LMPA component in the module using the heating chamber whose temperature reference was 60 [◦C]. After the melting, the LMPA remnant was moved into the stainless cup again.
