Chapter 34

a. Currently, you serve as a robotic engineer by a company, and your boss want you to design a robot in spatial space to satisfy the following conditions: i. Max reachable distance of the robot is 1 meter. ii. Only using revolute joints, connecting links and rigid load bearing links (the length of link is 0.5m). iii. The degree of freedom (Dof) of the robot is 2. What is your design, how many joints and links will you use? b. The payload of your design is 10 kg (each load bearing link can hold 5 kg, 5 kg+5 kg=10kg, the weight and payload of the connecting links will be ignored), but your boss wants your designed robots to handle 20 kg payload. How will you update your current design, and how many joints and links will you use in the new design? What is the Dof of the new designed robot.

Please choose the false answer(s) from the following statements related to CAD!   a. It can be used for programming of robots, which may operate in a workcell arrangement, selecting and positioning tools and workpieces for NC machines. b. It is a technology which uses computer system to assist in the creation, modification, analysis and optimization of a design. c. Geometry can be used as a basis for other functions in CAE and CAM, saving time and reducing errors caused by redefining the geometry of design. d. Basic role of CAD is to define the geometry of design (computer aided drafting, and geometric modelling are the most important component of CAD).

A robot is used for loading and unloading of parts to automated flexible machines. Loading time is 1 minute; unloading time is 1.5 minutes; machining time 15 minutes; Robot travel time between the machines including the inspection time is 3 minutes. Cost of robot C,=30 TL/Hour; cost of machines C2=40 TL/Hour. How many machines (integer number) should be assigned to the robot so that the total robot and machine costs per cycle are minimized? 8 - 176 a) 4 b) 3 c) 2 d) e) 6.

Question 45 is based on the following picture. Reprinted with permission from Popular Science magazine, ©2000, Times Mirror Magazines, Inc. 45. Stuart Wilkinson, the engineer of "Chew- Chew" said, "we stole the idea of eating food from the biological world, but we are marrying that idea to useful robotic capabilities." Which of the following would not be an application of Stuart Wilkinson's theory? A. A leaf mulcher that feeds on foliage B. a trash compactor that feeds on garbage dos C. a lawn mower that feeds on grass bos 9D. a garden cultivator that feeds on soil clippings E. a recycling truck that feeds on petroleum conjo

part b and c , (end-effector point A)

11. How might your machine or system be improved? What constraints might be involved in its design? Library/De Agostini/l

Question 26 and 27

I want to answer all the questions by handwriting.

Your capstone design team is prototyping (e.g. you are building a model to test not a final product) a "fire identification drone. The final product is intended to fly over rugged wilderness areas and look for small fires that should be monitored and potentially fought or contained. It is NOT intended to be used in large active fires. Your subteam's job is to design and build the support frame for the drone (e.g. the structure where the motors, propellers, guidance electronics and GPS, heat sensors, radio receiver and transmitter, etc. are attached) for the prototype. You have access to a machine shop with saws, lathes (for removing material by rotating it and using a cutting tool), drills and a facility with 3-D printers that can print a variety of plastics using fused deposition modeling (this is the technique where a polymer filament is melted and forced through a nozzle to build a structure layer by layer). You will be testing in a summer/fall timeframe so you expect temperatures…

Answer all the calculations questions, if you are not not expert please don't attempt, don't use artificial intelligence

b. ENGT 2020 -Robotic Fundamentals Lab 3.5 Creating a Program 1. What are the four types of moves and describe how they move between waypoints. a. C.

Q1: A. One of the researchers discovered a patent related to the development of a certain software module in mobile devices, and when he emailed one of the companies producing these devices, they asked him to send the research to try it on their devices, and after a while this researcher discovered that his discovery was used by this company without referring to him or buying this discovery, What do you think about the above. B. As a quality control engineer in one of the electrical appliance factories, I discovered that the technical worker responsible for inspecting one of these products seals its validity without inspecting it. when I filed a complaint with the administration, the administration neglected the complaint, arguing that there was no time to inspect it again due to lack of time to prepare the consumer. 1. What are the consequences of this action, it is possible that there is a bad in the product due to lack of examination. 2. The actions that you should take because of…
