本文报道了一种新设计的热步行者，它可以在没有任何电机或电池的情况下在热的水平表面上行走。步行者通过使用隔热板将来自热表面的热能转化为机械运动。在之前的研究中开发的原型成功地演示了行走，但它的步态并不理想;一条腿向前和向后摆动几次才能走一步。本文设计了一种新的步行者，实现更自然的步行，其中一条腿简单地向前摆动一次，在每一步。为此，本文介绍了一种新的设计过程，以更好地估计摆动周期。此外，重新考虑用于步行者的脚的材料，以实现稳定的连续步行。新制造的原型有铝脚，可以在热的水平面上以简单的步态行走。行走所需的表面温度为110 °C，比之前研究中的170 °C大大降低。
This article reports on a newly designed thermal walker that can walk on a hot horizontal surface without any motor or battery. The walker converts heat energy from the hot surface into mechanical motion by using bimetal sheets. The prototype developed in the previous study successfully demonstrated walking, but its gait was not ideal; a leg swings forward and backward a few times to achieve one step. This article designs a new walker to realize more natural walking, in which a leg simply swings forward once in each step. For this purpose, the article introduces a new design process to better estimate the swing period. Also, material used for the feet of the walker is reconsidered to realize stable continuous walking. The newly fabricated prototype has aluminum feet and can walk on a hot horizontal surface with the simple gait. The surface temperature required for walking was 110 °C, which was considerably lowered from that in the previous study, which was 170 °C.
