For the final project for robotics, I decided that I want to do a solo project as to explore and learn more about the robotic aspect.
Categories that I am interested in:
The use of Robotic Device to emulate human or animals, or to bring lifelike characteristic to inanimate object-
Puppetry (research to be done: Karakuri Puppets)
Usually powered by:
And controlled by:
Human (teleoperation like remote)
And further research must be done on:
Structure – Frame/Skeleton(Material, Skin)
Components – Types of motors and usage
They are self-operating machine or mechanism that automatically follow a predetermined sequences of operations, for me, they are more like the 3D – Dumb, Dull and Dangerous of robotics that does job that would reduce manpower.
The main aspect I think of Automaton is the ability of repeat-ability as they are supposed to do the same sequence over and over again so the zeroing of every cycle is of an importance here.
Areas to explore here:
Stepper motor VS Servo Motor
– Easier to control (1Pulse = 1 step)
– Higher Torque at low speed
– Relatively cheaper
– Accelerate too fast will result in skil step
– Higher vibration
– Generally High speed and High torque for given size
– Ability to maintain torque at high speed
– More efficient
– Does not vibrate much in comparison to Stepper Motor
– Generally more expensive
– Only limited types of servos
Stepper motor is good for low acceleration and high torque applications and Servo motor is good for higher speed and higher torque applications.
I could use 2 smaller servo to move a lever which is not capable by using only 1 servo instead of using a bigger servo (like 2x SG90D at 6V vs 1x HS322HD at 5V, but theres a limit to this)
I am more inclined to Animatronics as it seems much more interesting for me, after some research about Animatronics, Hexapods and Octopods are really common among the field of robotics due to the stability (6/2 = 3, and 3 feet on the ground will be stable) but then I am really interested in Quadruped which has 4 feet and an quadruped animal which I really like was the turtle/tortoise as they are interesting, generally does not move too fast and naturally have a shell, which seems logical to use a turtle as a base as their nature suits what I am looking for and it will be easier to hide all the components. So for now, I really want to give a Robotic Turtle some thoughts.
