EEZYbotARM MK2

pinshape

This is a 3D printed robotic arm. It builds upon the success of my previous smaller model EEZYbotARM, hence its name MK2 (make 2). The new design is slightly larger and stronger, allowing for an acceptable payload. It was designed with no specific purpose in mind, focusing instead on education, providing a versatile platform to explore various applications. The arm's kinematic linkage is inspired by the ABB IRB460, scaled down by a ratio of 1:7. I've also added several features, including a replaceable clamp with quick coupler and internal cable routing in the main arms. Additionally, the vertical axis is supported by spheres. I'm currently evaluating whether to add a counterweight or balancing spring for the main arm. The printing and first test video can be found here: EEZYbotARM MK2 first test. The following non-printed parts are required: - 3 or 4 model number 995 or 946 servos - 1 SG90 servo - 1 M6 self-locking nut - 1 M6x25 screw - 2 M3 self-locking nuts - 2 M3 x 20 screws - 1 M3 x 10 hex recessed head screw - 9 M4 self-locking nuts - 1 M4 x 40 screw - 1 M4 x 30 screw - 5 M4 x 20 screws - 1 M4 x 60mm threaded rod - 1 M4 x 32mm threaded rod - 25 Ø6 mm ball spheres - 1 606zz bearing - Some M4 washers Software and Firmware: As mentioned earlier, there are multiple ways to control the arm. The choice depends on whether you want to move it freely or have it repeat a loop. I found using a Pololu Mini Maestro card easy, as it doesn't require any code writing. However, I've made an Instructables: Android APP to control a 3D-Printed Robot available online, which includes some code. I'll be making updates in the coming days. Happy Robotics!

It requires a printing area of about 200x200 mm, and some pieces need to be printed with supports enabled.
