科学研究课题投影仪的使用非常普遍,但是,它要么装在屋顶天花板上,要么固定在地上,很不方便。于是我想到,要是投影仪能朝任意方向投影、方便调节、便于移动,甚至躺在床上就可以观看投影,该多好。研究过程与心得制作“可移动万向投影仪支架”需将普通三脚架与转向装置进行合理组 The use of projectors is very common in scientific research projects, but it is either inconvenient for either being installed on a roof ceiling or fixed to the ground. So I thought, if the projector can be projected in any direction, easy to adjust, easy to move, even in bed you can watch the projection, which is good.
