Teleoperation Bionic Mechatronic System

There are often informations about the new bionic hand design. These are both commercial solutions and student projects. But from time to time there is designed a mechatronic system, which is impressive in terms of technical advancement.

Dexterous Hands developed by Shadow Robot Company are nowadays one of the most advanced humanoid robot hand. Shadow Robot currently offers 2 types of hands with different technical capabilities:

  • Shadow Dexterous Hand, 20 actuated Degrees of Freedom (DOF) and a further 4 under-actuated movements for a total of 24 joints, its weight is 4.3 kg and its maximum payload is 4 kg.
  • Shadow Dexterous Hand Lite, 13 DOF across 16 joints, its weight is 2.4 kg and its maximum payload is also 4 kg. It is a smaller, lighter, cost-effective package. There’s no little finger (unnecessary for nimble tasks) or wrist (for easier mounting onto a broader range of robot arms).
The Shadow Dexterous Hand is our flagship product. It’s the ONLY robot hand on the market to have 24 movements and 20 degrees of freedom (DOF) for increased flexibility in grasping and manipulating a range of objects.

Both mechatronic systems are compatible with EtherCAT interface, ROS open source platform, standard pressure sensor tactiles (PSTs), standard force sensors, easily integrated on robot arms and upgradable with other components.
Shadow Dexterous Hand's fingers move side to side independently, for unparalleled dexterity and there’s a total of 129 sensors to increase accuracy and enable high-level precision. It approximates the kinematics of the human hand including the thumb, the flex of the palm for the little finger, and even the fingernails.

Dexterous Bionic Hand application areas:

  • Research & Development
  • Nuclear Safety & Decommissioning
  • AI/ Machine Learning
  • Teleoperation
  • Manufacturing
  • Telepresence/ Avatars
  • Pharma & Biomedical
  • Space Robotics 

It uses an open-source platform giving researchers full access to the code along with editing ability to help researchers develop software for their own specific needs. AI and machine learning researchers have programmed the Hand to provide naturalistic simulations in a way that simple computer-driven algorithms cannot.

    What is Mechatronics?

    Mechatronics definition Mechatronics is a synergistic combination of precision engineering, electronic control and mechanic systems. It is the science, that exists at the interface among the other five disciplines: mechanics, electronics, informatics, automation, robotics. It is one of the most dynamically developing fields of technology and science. The word 'mechatronics' appeared for the first time in Japan in 1969. mechatronics = mecha nics + elec tronics + computing

    Ascento - The Two-Wheeled Jumping Robot

    All-terrain capabilities are required to extend beyond flat surfaces the application range of wheeled robots. First think is four or six-legged robots which have been well known for years. Nowadays, thanks to more and more perfect gait algorithms, the two-legged (bipedal) robots appears more and more often. ETH Zürich students combine the advantages of wheeled robot and two-legged robot.

    How Automated Parking System Works

    An automated car parking system is a mechatronic system designed to transport and park cars automatically. The first semi-automated parking system was used in Paris, France in 1905 at the Garage Rue de Ponthieu (the car was transported to selected level using an internal elevator and the vehicle was parked by attendants). An automated storage and retrieval system for cars is a solution to cities' parking problems, such as the space wasting in a multi-story parking.

    Mechatronics System as the Future of Cooking at Home

    Do you get up in the morning and don't feel like making breakfast? One of the solutions is food delivery service, which leaves your takeout order outside of your front door. Other solution is a private chef who is responsible for shopping for food, menu planning, preparing and cooking meals for you. But if you love mechatronics systems, your solution is a mechatronic kitchen. It allows you to save time, free up your day from routine cooking, plan and adapt your menu according to different diets and lifestyles.

    Automatic Sorting of Skittles or M&Ms by Colour

    Do you sort M&Ms or Skittles by colour before eating them?  For example, eat all the yellow ones first, then the red ones, then the blue and so on. Brian Egenriether, an electrical engineer, decided to make a small machine that looked like an appliance, which could perform these tasks automatically. This mechatronics project took him about 5 weekends to make. The use of the machine is very simple: pour Skittles or M&Ms into it, push a button and have candies sorted. Let us look at the construction.

    Where to Download 3D CAD Models? Online Libraries, Collection, Community

    Each novice designer may have a problem with obtaining 3D CAD models for their projects. Preparing models on your own is time consuming and often unnecessary. To save your time when choosing the components, check if the distributor or manufacturer does not offer on their websites available ready-made 3D CAD models to download. By downloading models directly from the manufacturer we can have a greater chance that the model reproduces 100% of the actual product.

    Three Wheels Balancing Robot

    The three wheels balancing robot is similar to a ballbot from the point of view of the goal. In comparison to ballbot which balance itself on a single ball, three wheels balancing robot is designed to balance itself on a single rod. The common characteristics of this kind of robots is that there’s one sole contact point to the ground.

    DIY Low Cost 6-Axis Desktop Robot

    Learning how to build a robot is a long way. It is the way by mechanics, electronics and programming. Such a mechatronics project is associated with problems such as stiffness (mechanics), overvoltage (electronics) or bug (software). Of course, if something is wrong, we always say 'it's not a bug, it's a feature', but finally a robot has to start working properly.
