we make use of the Studica set(the photo that is shown above) to build up the robot.
The photo on the left is build by me and my partner. It consist of 3 different parts. First there is a robot base then the robot arm and we have a special design the basket. So the robot will pick up an item and it will move back and drop at the basket. Then it will move to a box and the basket will turn downwards and the item in there will drop into the destinated area.
This is a video of me and my partner building up the robot.
