Humanoid Robot Hand – 2015

The Project

As part of the course, Product Life Cycle Management (PLM), under the supervision of professor Salehi, our team had to develop a humanoid robot hand.

Our Task:

  • Application of PLM for the development of mechatronic systems
  • Processing of topics associated with the development of mechatronic systems based on PLM systems
  • Representation of the various disciplines of mechatronics (mechanical engineering, electrical engineering and computer science) in PLM
  • Representation of actuators and sensors of the robot hand
  • Creation of requirements for the development of the robot hand
  • Creation of functional aspects in the development of the robot hand
  • Creation of logical interactions in the development of the robot hand
  • Geometric drawing of the components of the robot hand

I was responsible for the entire development of the electronics, including microcontroller  programming, component selection, the sensor and the actuator.

How It Works:

The hand itself is 3D-printed using the FORMIGA P 110, a laser sintering 3D printer from the company EOS.

The electronic components are the following:

  • ARM Cortex-M3 Microcontroller (NXP LPC1769)
  • HiTec HS-485 HB
  • Spectra Symbol Flex Sensor SEN-08606
  • Rayson BTM-222 Bluetooth Modul

The hand works with two separate microcontrollers, one on the robot hand and the other on the glove. The communication takes place via Bluetooth.  The sensor in the glove is a flexible resistor that increases resistance with increased angle. In this way the fingers of the robot hand can be controlled.
