This document summarizes the design process of a bio-inspired walking robot. It began with four conceptual designs, two using one servo and two using multiple servos. After analysis, a design mimicking a seal gait was selected as the simplest. Statics and kinematics analysis determined a 2:1 gear ratio was needed to provide sufficient torque. The robot was built, but initially the servo could not handle the weight. Weight was reduced and arm lengths adjusted, allowing it to successfully walk 4.9 meters as required. The analysis upfront helped produce a simple, robust design that performed well.
The biological inspired robot project involved designing and building a robot that could autonomously travel 4.9 meters on an inclined track using legs instead of wheels. The robot was inspired by a snail and built from MDF and servo motors. It successfully completed the track but moved unevenly. Alternate designs based on ants were analyzed but proved too complex. Calculations showed the snail design was feasible. Foam was added for traction after initial tests found the drag box hindered movement. With some improvements, the robot could complete the track more smoothly.
The group designed a robot to complete tasks involving scanning an area for specific canisters and transporting them to a specified location using four sensors. The robot design features a sturdy base with two large wheels and one small wheel for turning. Grippers in the front hold color and ultrasonic sensors to identify canisters. Motors power the wheels and gripper, which uses gears to open and close. The algorithm involves scanning with ultrasonic and color sensors to identify canisters, opening the gripper to grab them, and using light and color sensors to navigate to the drop-off zone. Limitations of only four sensors required strategic sensor placement and a design to minimize interference.
This document discusses forces and their effects. It begins by defining a force as a push or pull and discusses different types of forces. It then explains how forces can affect motion by changing an object's speed, direction of motion, or state of rest. Methods for accurately measuring length, time, speed and acceleration are also presented. Distance-time graphs are introduced and examples of calculating speed from these graphs are shown. Finally, the concept of moment of a force is defined and everyday examples like opening a door are described.
This document provides an overview of forces and simple machines. It begins by defining a force and giving examples of different types of forces. It then discusses how forces can be measured using spring balances and the unit of newton. The effects of friction and how it can be both useful and a nuisance are described. Finally, the document introduces three common simple machines - levers, inclined planes, and pulleys - and explains how each one makes work easier through mechanical advantage. Real-world examples of each simple machine are provided.
This document describes the design of a 3-point bending device to measure beam deflection. Several proposed solutions were considered, including a computerized model and design with fixed supports and movable load hook. However, these had issues like complexity, inability to measure at the load point, and reaction forces acting on a circular not point surface. The final design uses knife-edge supports and a different load application method. Testing involved applying fixed loads at different positions and measuring deflection to study beam behavior and determine material properties. Practical problems in implementation included orienting the knife edges perpendicular to the beam and support tip accuracy.
This document outlines the mechanical design of MEMS gyroscopes. It discusses the basic mechanical structures of linear and torsional vibratory gyroscopes, which are based on conservation of momentum and angular momentum respectively. Key challenges discussed include decoupling the drive and sense modes, minimizing anisoelasticity and quadrature error from cross-axial stiffness, and reducing damping effects like viscous and anisodamping. Vacuum packaging is important to address damping issues.

Explanations of Design Decisions
The feasibility study of our project was based on a four bar linkage and six-bar quick return linkage mechanisms. The four-bar linkage is the simplest pin jointed mechanism for single degree of freedom controlled motion. It could generate many different motion depends on the links length, and it is the most common device used in machinery. Whereas the six bar mechanism is more complex mechanism and needed for a difference in average velocity between their forward and return strokes.
The decision of choosing a design was made in order to include what has been studied in this course. Therefore, four bar linkages and a six bar quick return mechanism was chosen to have a mechanism that could make a full revolution and transport a body 90 degrees. After a careful consideration the group members have finally decided to design a mechanism to handle brick transport. It was difficult at first to choose a design since everyone liked different design, so each member in the group asked to sketch their desire design and the best one was selected.

IRJET- Design and Fabrication of Multi Legged RobotIRJET Journal
1. Students designed and fabricated an eight-legged walking robot based on the Klann linkage mechanism to test new walking algorithms.
2. The Klann mechanism converts rotary motion of a crank into linear movement of the leg, simulating an animal's gait. Two linkages are coupled 180 degrees out of phase to allow the robot to walk.
3. An analysis of the robot and leg mechanisms was performed using ANSYS software to evaluate stresses, deformations, and fatigue over time. The results provide data to optimize the robot's design qualities and walking performance.
This document summarizes robotics projects the author worked on for FRC competitions in 2013-2014. It describes modifications made to the robot's drive base and bumpers in 2014 to prevent the robot from getting pinned, including changing to a hexagonal frame and adding low-friction fabric to the bumpers. It also discusses software projects for ball manipulation, a two-stage crank mechanism for launching balls, automatic ball tracking using a Kinect, and creating an automation framework to structure the robot codebase.
The robot, named Gaitor, was designed to mimic the gait of an alligator in order to walk a distance of 30 times its largest body dimension within two minutes. It was modeled after the alligator's belly crawl gait and constructed using 3D printed parts and eight servo motors. Testing showed that it could travel the required distance on both carpet and concrete in under two minutes, completing the carpet course in 1 minute and 32 seconds with three repositions and the concrete course in 1 minute and 27 seconds with one reposition. While successful overall, the robot had a tendency to veer slightly left after traveling a short distance in a straight line.

based in the robots sent into space. Also, it describes of software to acquire the image in real time and the
control of robot. It should be noted that space exploration has been a feature of governments for many
years. Nowadays there are companies that can transport loads to space; There are also companies that
have made great advances in robotics and manufacturing.These technological advances can help in space
exploration, either by making robots lighter and easier to manufacture or even by creating pieces and tools
from space.
This document summarizes the design and 3D printing of an explorer robot with a rocker-bogie suspension system. The robot was designed using CAD software and printed using PETG plastic. It utilizes a Raspberry Pi computer, camera, battery, motor drivers, and 6 motors to enable remote control and video streaming capabilities. The rocker-bogie suspension allows the robot to navigate difficult terrain and obstacles up to twice the diameter of its wheels. 3D printing was chosen for its low-cost and ability to rapidly manufacture replacement parts if needed.

Abstract— The goal of this paper is to obtain a complete
understanding of the concepts required in the design of a bio-
inspired robot. The general concept and thinking behind the
project, as well as the analysis of the reason behind the success
of the project is the essential purpose of this project. Statics and
kinematics were the main mathematical base to the entirety of
the project. The ability to realize how each part was going to
react with one another was the most essential ability to obtain
during the process of the design. The goal of this paper is to
go over the design process, and to highlight the entire thought
process of the entire design process.
I. INTRODUCTION
For the third project in MMAE 232 - Design for Innova-
tion, it was required that we design a bio-inspired walking
robot (see Fig. 9). The robot had to use a servo, or a system
of servos, and had to resemble a gait of a biological being.
The robot had to be able to walk 4.9m autonomously, and
once it completed the 4.9m walk, we had to pick it up and
move it to the start line to complete its second trial. The
design also had to be disassembled, meaning glue could not
be used to hold any of the electronics in place.
II. CONCEPT GENERATION AND EVALUATION
Our four original designs had two that consisted of one
continuous servo, making it as simple as possible for the
design process (see figs. 2 and 3). One of them was going
to represent the gait of a duck, and the other represented a
seal. The other two designs were a little more difficult(see
figs. 4 and 5). The design with a similar gait plot to a dog
was going to consist of four servos that would move each
leg individually (see gait 3). The design that resembles a
gorilla was going to move with one continuous servo in the
front with two servos that work individually in the back. By
further inspection of both the gorilla and the dog designs,
we realized it was going to be much more difficult to make
these two designs. The timing of the gorilla gait was going to
be very difficult to time out. And the dog gait may have had
to use eight servos instead of four in order to work properly.
We then did a Pugh chart to determine the strengths and
weaknesses of each potential design (see Table 1). We then
decided that the seal gait was going to be the easiest to
mimic, and it was also going to require the least amount of
time to design.
III. ANALYSIS
The most important part of the design process was deter-
mining whether the system was going to be statically stable
in all phases of the entire gait. On top of this, the amount
of torque necessary to move the design had to be found as
well. This was found using a free body diagram (see fig. 8).

This free body diagram shows the very instant that the body
begins to lift. Since we made the base so long, we knew that
it would never come completely off the ground. This was a
design feature that allowed us to use two arms to propel the
design forward. Once the design is lifted off of the ground,
the only force that has to be overcome is friction. Since most
of the force will be resting on the arms, we knew that the
frictional force was going to be much less than the force
necessary to lift. Therefore, the distance (d) from the center
of mass to the reaction force (FR) is 150mm. The distance

3. from the force necessary to lift (Farm), and the reaction force
is 220mm. If you do a sum of the moments equation, you
will be able to find the force necessary to lift the object off
the ground. The weight of the project including the servo is
about 9.8N:
M = −((Fmg) ∗ d) + ((Farm) ∗ d) (1)
0 = −(9.8N ∗ 150mm) + (Farm ∗ 220mm)
You find that Farm = 6.68N. This is the maximum force
allowed to keep static equilibrium. Therefore in order to
break static equilibrium, you need any force greater than
6.68N. In order to find the minimum torque necessary, you
will use this number in the equation used in the torque free
body diagram (see fig. 9). In order to find the minimum
torque required to lift the seal’s body, you will use:
Tneeded = Farm ∗ larm ∗ sin(θ) (2)
Tneeded = 6.68N ∗ 100mm ∗ sin(49)
Tneeded = 505Nmm
You find that the torque necessary is about 500Nmm. This
is well over the maximum torque that the servo can handle.
We then decided to use gears in order to increase the amount
of torque that the servo can apply to the arm. The gear ratio
we decided to use was 2:1, and we placed the smaller gear
on the servo. This would in turn slow down the speed of
the motor, yet would double the amount of torque that can
be applied to the arms. Now that we found that we need
500Nmm of torque to lift the body, the 2:1 ratio will cause
the amount of torque that was needed by the servo motor to
be 250Nmm, which is well under the maximum allowable
torque given by the servo.
IV. EXPERIMENTAL RESULTS
The project went relatively smooth, other than the need
to cut weight. When the entire design was put together, the
servo could not handle the torque necessary to rotate. We
decided to scrap most of the design that was unnecessary to
motion. We also cut weight off of pieces that were oversized
and unnecessary as well. By the time we got the design to
move, we had cut out everything but the necessary pieces
(see fig. 1). As you can see in the figure, we didn’t precisely
cut anything off of the project. All that was necessary for
motion was the base, to stabilize the design during motion,
the gears, the two pieces that held the servo, the two pieces
that stabilized the rod, and the arms, which pulled the design
forward. After the weight was cut, the design began to move,
but it rotated to the right as it moved forward. So we began to
shave down the arms to make sure they were the exact same
length and were only in contact with the floor at the same
exact time, otherwise it was going to rotate in the direction of
the arm that had less contact with the floor. After these minor
adjustments we were able to get the design to perpetuate
forward with almost no rotation. Our design walked the 4.9m
in both directions with no issue. I had more confidence in
this project than the other two we had done earlier in the

semester. This project actually took less time to design than
the other two had as well.
V. DISCUSSION
As stated previously, we had issues with the weight of
the design, and the contact time for both arms, but other
than this, we had no issues with the design. The reasoning
for the issues with the weight is because we underestimated
the amount of weight that was going to be involved in the
design. Then when we cut the arms, which was done because
they were too long, we had issues with the amount of time
the two were in contact with the ground. After these two
were fixed, the project needed no adjustments. The servo
was continuous so there was no timing involved. The project
went as expected after the minor adjustments.
VI. CONCLUSIONS
This project went as smoothly as it possibly could have.
The key to the simplicity of this project had to do with the
analysis done prior to the project being designed. As soon
as we figured out what we wanted to do for the project, we
made an effort to achieve simplicity throughout the entire
design process. This attempt for simplicity made any issues
extremely easy to fix. Any issues that we ran into had no
effect on the rest of the project. This feature in the design
process is something that we can use in the future. It makes
for less complications, which allows for less time wasted.
