This article introduces a multidisciplinary skill assessment for learning embedded software development. In the industry, software engineers and mechanical engineers have to communicate with each other, and hence, these engineers need to have multidisciplinary skills. For learning such skills, we need to give an occasion to work with different field students. To this end, we have been organizing a robot contest with embedded software development education. One of the goals of the contest is to inculcate multidisciplinary skills. However, we have not clarified the contribution. Thus, we construct a multidisciplinary skill assessment map based on the experiences gained through these contests. The map consists of (1) integration skill, (2) performing skill, and (3) cross-understanding skill.
