End Effector Design

Thread programming is a key element

Thread programming in writing high speed stream of data is a key point in navigation systems. Effective DAQ system is critical in such systems and the idea of synchronization between different threads and the communication channels between different threads are also very important. More about this later ...

Challenges ...

New challenges with the robot arm, while I am working with positioning. The prototype(robot arm) is not totally functional as just one of the three motors work the way it should. Problems with mechanic design, and the motor axle is worn away(3D printer product in plastic) ...
