By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.
,这一点在51吃瓜中也有详细论述
第二个问题在于,狗加双臂是一个非标的构型,我觉得我们做机器人公司,一定要杜绝按照非标的构型思路。因为非标意味着无法放量——今天臂长要1.5米,明天要2米;今天精度0.1毫米,明天要1毫米——这样就会量上不去,成本降不下来,算法也无法复用。,推荐阅读旺商聊官方下载获取更多信息
