Tri_Max_Gripper ( Conforming Robotic gripper )

youmagine

Designed by Chiprobot, this robotic gripper adjusts its grip to conform perfectly to the shape and form of any object picked up. Interest in this gripper has been overwhelming, with thanks to all for their kind messages. The Gripper has now been featured on Hackaday, showcasing its impressive abilities without scrambling delicate objects. Printed with normal PLA, which does not require flexi pla, this gripper is a marvel of simplicity and effectiveness. A video demonstrating its capabilities can be found here, along with details of the build process on Chiprobot's robot page. The drive mechanism consists of a standard servo modified to include a linear actuator made from a "Glue stick" and linear feedback potentiometer. Details on servo conversion are available here: Instructions for building this robotic gripper are straightforward. Print parts using normal PLA, with STL files oriented for printing without support. Slow down the printer as needed during the last part of printing the support beams. Glue three (red) support beams to the front (blue) body and add wire between the eyelets of the three arms. For a more detailed understanding of the actuator build, watch the above videos or visit Chiprobot's robot page for additional information. To assemble the gripper, fit in the linear servo mechanism using a Pritt-stick as the body and a lip gloss tube as the plunger. Glue the plunger insert spigot inside the lip gloss tube and attach the plunger crown (green) to the top of the lipgloss tube. This setup allows for fine tuning by sliding the crown up/down to bring the gripper ends together, resulting in maximum grip. The servo used is a standard HS-311, which can push 3kg of force when converted to a linear actuator.
