Hello, everyone! My name is Wilmer Gaona. I am a mechanical engineer of the Universidad Nacional de Colombia, Bogota, Colombia and I have a PhD ;in Computational Modeling and Scientific Computing from the Universidad Autónoma del Estado de Morelos, Cuernavaca, Mexico.From I have memory, I have ever been interested ;in the mechanics and electronics stuff with the purpose of building machines and ;robots for helping people. I love building things, for this reason, I have learnt about microcontrollers, electronics, embedding computing, ;programming, ;digital control, 3D modelling and 3D printing. And of course, I am building the Thor Robotic Arm because it is so interestingbecause it combines all of this kind of knowledge in a practical way and it could be applied in a real industrial environment.
