rad vs degree - Githubissues

OpenRoberta / openroberta-lab

The programming environment »Open Roberta Lab« by Fraunhofer IAIS enables children and adolescents to program robots. A variety of different programming blocks are provided to program motors and sensors of the robot. Open Roberta Lab uses an approach of graphical programming so that beginners can seamlessly start coding. As a cloud-based application, the platform can be used without prior installation of specific software but runs in any popular browser, independent of operating system and device.

rad vs degree #134

Open rbudde opened 6 years ago

rbudde commented 6 years ago

we have to decide, whether we use rad (pi/2) or degree (90°). This has to be consistent for all robots. Degrees seems to be the best choice (or?).

With Calliope, we have 2 errors:

the simulation expects rad, the robot degrees
asin(1) on the robot returns 89.1 instead of 90.0

+1 for degree. At least in Germany this is the unit that is used in schools, right?

We carefully have to decide when and how we change something. E.g. for real EV3's some implementations of trigonometric functions expect and return radians, same for simulation. When switching to degree, the users programs will fail.

Seems that we should start to work on this. Let's decide to use degree and only degree for NEPO, please comment if you can't agree on this.

+1 degree

Proposal: add dropdown to related blocks to let the user define this
