Pocketdelta robot

Pocketdelta robot is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pocketdelta robot rather than just read about it. In short: The PocketDelta Robot is a microrobot based on a parallel structure called "Delta robot". It has been designed to perform micro-assembly tasks where high-speed and high-precision are needed in a reduced working space.

Key takeaways

Pocketdelta robot belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Pocketdelta robot to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Pocketdelta robot from memory before moving on to harder problems.

Reference excerpt

The PocketDelta Robot is a microrobot based on a parallel structure called "Delta robot". It has been designed to perform micro-assembly tasks where high-speed and high-precision are needed in a reduced working space. The robot's size is 120×120×200 mm offering a workspace diameter up to 150mm × 30mm.

Design Prerequisites to high-speed and high-precision are a light, but stiff mechanical structure. Thus stiff and lightweight materials build up the moving part of the robot, whereas the heavy motors are attached to the supporting frame. The motors are attached directly to the robot arm (direct drive), eliminating backlash, friction and elasticity. A high-level of integration reduces the size of the whole system. The mechanics, motion drives, control electronics and computing are all integrated into one compact unit. This innovative configuration simplifies its use and increases the flexibility of the robot. The controller is based on PC architecture with interface boards for communication with the robot hardware. The realtime software enables the generation of trajectories in the Cartesian space using a direct and inverse kinematics model of the robot. The robot integrates a web server which enables an easy communication through an Ethernet network using HTTP, TCP or UDP protocol.

History 2004: The first prototype is developed at the microRobotics Lab of the Bern University of Applied Sciences in Biel (CH) Archived 2005-08-31 at the Wayback Machine as a part of a new project on "Microfactory"'s topic launched by the CSEM SA (CH) in collaboration with the EPFL (CH) 2005: CSEM SA develops a new version of the robot and introduces it as the "world's smallest Delta robot" March 2007: CSEM's «Smallest Format Factory» and PocketDelta robot win the Swiss Technology Award and are nominated for the Hermes Award 2007: The company Asyril SA was founded as a spin-off company from CSEM. The company developed the current version of the PocketDelta robot together with its sister company CPAutomation SA and has been commercializing the robot as a tool for highly precise micro-mechanical manipulation as well as flexible part feeding systems.

Applications Typical application's domains for the PocketDelta robot are the following:

Watch and precision mechanics Assembly of medical devices Surface mount technology, semiconductor and electronic parts assembly MEMS and MOEMS System in package (SIP) Biochips

Worked examples

Example 1 — a first encounter with Pocketdelta robot

Start with the simplest possible case. Write down what Pocketdelta robot claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pocketdelta robot before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pocketdelta robot ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pocketdelta robot

In research: Pocketdelta robot appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pocketdelta robot in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pocketdelta robot is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2004 robots, Delta robots, Micro robots, so understanding it makes those chapters shorter.
In everyday life: Look for Pocketdelta robot outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
