针对减速器，目前就衍生出了多种改良方案。针对谐波不耐冲击的特点，有安装尺寸、外观与谐波相似却更耐冲击的摆线针轮减速机；为降低成本，有使用注塑工艺替代金属加工的谐波减速机；还有企业致力于优化传统行星减速机，提升精度、降低齿隙、提升负载能力。此外，直驱关节方案也已进入应用验证阶段。电机也有多种改良方案，比如轴向磁通在关节电机中也得到了应用。
The first problem is wasted work again. If cell A1 references B8, and cell A2 also references B8, then when we update all the cells, we still only want to evaluate B8 once, and then reference it in both A1 and A2. We can do this through caching — whenever we calculate a cell’s value, we store it somewhere, and then all future cell references can used the stored value instead of recalculating.
