The finger will be controlled using strings on a coil attached to dc motors. To plan out all the electronic parts, I would use Tinker cad.Īs mentioned before, the user will use a variety of sensors to control the arm. To make the design as light as possible, I will place holes inside the arm design to reduce material usage and thread wires through the arm. Depending on the location on the arm, the motors used will need to be able to lift the weight of the mechanism. For the movement of the arms and hand, I will use a combination of step motors, dc motors, servo motors, and possibly Vex motors. To take up as little space as possible, I'm going to use 2 Arduino Nanos to use. To use the transceiver module, I would need to learn about how to program the module to work with the Arduinos. Since the sensor system would need to be wireless from the mechanical arm, I would need to use a transceiver module to make the Arduinos communicate with each other. The electrical system will involve a lot of different sensors to detect movement on the user’s arm. I will make sure that the motors will be able to handle the weight of the arm, so it doesn’t collapse on itself. To save some time, I will also use an existing prosthetic model (K1 arm) and modify it to accommodate the design. Factors to consider while making the model would be the orientation of the arm to match the user's arm, the weight of the arm, motor placement, sensor placement, wiring, and Arduino hub. Before making the models that will be printed, I would model the motors and sensors I would use into the models to use as a reference while creating the pieces. If, for whatever reason, you refuse the customs fee and the parcel is returned back to us.For the mechanical part of the build, I would need to model all my parts in Fusion 360, with careful attention to measurements of motors and sensors that would incorporate into the model. If you do have to pay Customs Duty though, the amount payable is usually calculated based on the value of the goods and the type of goods being imported. For example, many countries have a 'low value threshold' below which they do not charge any Customs Duty. Whether Customs Duty is payable, and by how much, depends on a whole lot of different things. If Customs Duty is payable to your territory, you'll be responsible for paying it to the authorities, so SunFounder isn't involved in this process. This is charged by the local customs authority where the goods are being imported into. When goods are imported into a different country or customs territory, there is a charge called Customs Duty that must apply.
