COURSE WORK 1

br>ROBOT LINKAGE ANALYSIS AND KINEMATICS

1 Introduction

The pace of population ageing is much faster than that in the past with an increasing number

of individuals suffer from mobility challenges. The major barrier for such individuals to

accomplish their daily physical activities is the ability to stand from a sitting position.

This group coursework is to generate an analysis report on the design of a robot that could

provide effective assistance to overcome the mobility challenge for the elderly and persons

with disabilities. A group report can be submitted by a group representative but with a front

cover page stating each person’s task and responsibility in the group work. Each member of

the group needs to submit one page per person to describe own contributions, results,

achievements, and experience learned.

2 Task

You are given a design prototype of a sit-to-stand robot. The mechanism and the active joint

are shown in Figure 1. The red circle indicates the end-effector of the robot which would be

attached to the user’s leg (link 8) with a revolute joint. In the sitting configuration, link 8 is

parallel to the x-axis while in the standing configuration, link 8 is parallel to the y-axis. Figure

2 and Table 1 show the position of each joint at the initial configuration.

The tasks include:

Illustrate schematic representation of the robot

State the mobility of the robot

Determine whether the leg linkages affect the mobility of the robot and

explain your result.

Identify and state the Grashof condition of the mechanism used in the robot

Analyze the mechanism by the vector-loop method

Plot the workspace of the end-effector and determine the range of the input

joint angle.

3 Report Requirement

? The report should be well written and well presented

o Very few typos/spelling/grammatical errors

o Use proper figure labels and captions

o Cite literature used as a basis of report

o Present your findings in a logical and intelligent way

The report should touch on the various aspects listed above.

The report should contain 8 — 12 pages of the main body of the report containing no

more than 10 figures. This page limit does not include title sheet, table of contents,

references or appendices. Additional figures may be presented in Appendices. Please

use Times New Roman, 12 pt. when preparing report, and use 1.5 line spacing.

A group report can be submitted but with a front cover page stating each person’s

task and responsibility in this group work.

One page per person needs to be submitted to describe

4 Report Structure

The report should contain the following sections:

1. Abstract.

2. Introduction

3. Background and literature review

4. Methodologies of the tasks

5. Work of the tasks

6. Results of the tasks

7. Conclusions of each of the tasks, discussing the results

8. General conclusions
