Overview
Mechanical Design
The Swayat Torso was designed using reconfigurable 3D printed ABS plastic modules. These modules can be re-arranged according to requirements of torque and workspace required by the arm.
The use of Dynamixel AX-12A Smart servos allows high torque in a small space and therefore the arm can lift heavy payloads. |

Grasping Abilities
|
The Swayat torso uses a unique spring constrained gripper which provides a powerful grasp on objects held in it. The open structure of the gripper enables a variety of shapes of objects (deformable and rigid) to be held into the gripper with even force applied to the surface of the object.
|
Writing Abilities
By the use of accurate and repeatable actuators along with precise closed form kinematic solutions for the arm of the Swayat, it can write letters and words provided to it.
This is done by mounting a pen on the end effector of the arm and providing additional actuator for vertical motion of the end effector. |
Features
