I am building a planar RR arm to be used for drawing. The arm will use two servos for joint control and be made of predominantly polycarbonate. At the end effector is a pen holder which will allow the robot to grasp a pen. The robot will create continuous line drawings based on images that are converted into path files. Below are some additional images of the arm design including my concept sketches.
For my Mechatronics class my team and I were assigned to build an automated can crusher. The crusher is to be loaded with 10 uncrushed cans and then output 10 crushed cans in under 2 minutes. The following video demonstrates our can crushing device.
Our team still needs to solve the issue of loading cans into our crusher through some sort of hopper device, but for now, we are satisfied with our can crusher.
A few tech specs:
6″ throw, 1.5″ bore diameter pneumatic Cylinder
Operating Pressure: 100 psi
Control is achieved using a 4-way solenoid valve paired with a L298 based motor driver.
An Arduino Mega provides the smarts.
