Use Photoshop to make an image of your robot design from screenshot images of the apps you are using - digital.school.nz/photoshop
In this video I used (hotkey) shortcuts to select the tools. The main Photoshop tools I used were: Magic Wand tool (W), Eraser tool (E), Transform tool (T), Move tool (V), Rectangular Marquee tool (M). Ctrl X + V for cut/paste parts of images to new layers. Rasterize your images before you edit them, right click image in Layers.
