Building Robot Drive Trains (Tab Robotics) [Dennis Clark, Michael Owings] on biosworisbeca.ml *FREE* shipping on qualifying offers. Publisher's Note: Products. This thesis aims at building a locomotion mechanism that forms the base of a . Safety Trophy is to develop an autonomous robot that is able to drive safely from .. differences in the motors, friction differences in the drive trains, and friction.
Typically, robots on two legs can walk well on flat floors and can occasionally walk up stairs.
None can walk over rocky, uneven terrain. The robot's onboard computer tries to keep the total inertial forces the combination of Earth 's gravity and the acceleration and deceleration of walking , exactly opposed by the floor reaction force the force of the floor pushing back on the robot's foot.
In this way, the two forces cancel out, leaving no moment force causing the robot to rotate and fall over. However, it still requires a smooth surface to walk on. Initially, a robot with only one leg, and a very small foot could stay upright simply by hopping.
The movement is the same as that of a person on a pogo stick. As the robot falls to one side, it would jump slightly in that direction, in order to catch itself.
A bipedal robot was demonstrated running and even performing somersaults. Main article: Passive dynamics Perhaps the most promising approach utilizes passive dynamics where the momentum of swinging limbs is used for greater efficiency. It has been shown that totally unpowered humanoid mechanisms can walk down a gentle slope, using only gravity to propel themselves. Using this technique, a robot need only supply a small amount of motor power to walk along a flat surface or a little more to walk up a hill.
Left one has 64 motors with 2 degrees of freedom per segment , the right one A modern passenger airliner is essentially a flying robot, with two humans to manage it. The autopilot can control the plane for each stage of the journey, including takeoff, normal flight, and even landing.
One approach mimics the movements of a human climber on a wall with protrusions; adjusting the center of mass and moving each limb in turn to gain leverage. An example of this is Capuchin,  built by Dr.
Ruixiang Zhang at Stanford University, California. Another approach uses the specialized toe pad method of wall-climbing geckoes , which can run on smooth surfaces such as vertical glass. Examples of this approach include Wallbot  and Stickybot.
According to Dr. Li, the gecko robot could rapidly climb up and down a variety of building walls, navigate through ground and wall fissures, and walk upside-down on the ceiling. It was also able to adapt to the surfaces of smooth glass, rough, sticky or dusty walls as well as various types of metallic materials. It could also identify and circumvent obstacles automatically.
Its flexibility and speed were comparable to a natural gecko. A third approach is to mimic the motion of a snake climbing a pole. Therefore, many researchers studying underwater robots would like to copy this type of locomotion.
Festo have also built the Aqua Ray and Aqua Jelly, which emulate the locomotion of manta ray, and jellyfish, respectively. Huosheng Hu at Essex University.
A typical sailboat robot is Vaimos . English In this tutorial I'll show you an EV3 construction that could give you ideas for building your competition robot or you could just use it as a base for your robot.
It consists of two large motors that drive the robot, one medium motor that could be used to power additional attachments, two light or color sensors for orientating on the field and, of course, a brick. Below the materials tab following the video you could find pdf instructions on how to build these modules. There is also a pdf file where you could find instructions on how to build the whole robot.
Now, I'll assume that you have already built the modules and I'll go through the process of assembling them and focus on some of the key features of the construction. First of all, we have the two large motors and you may notice that there are these Lego pieces at the back of the motors.
Their purpose is to hold the cables firm so, before we proceed with building the robot, we have to take them out, take a cable, put it into the motor, hold the cable firm and put the Lego pieces back.
This is quite a good technique to have the cables in place and you could use it in other constructions as well. Now I'll do the same thing on the other motor. Again, put a cable into the motor, hold it firm; and put the Lego pieces back.
Now I can proceed with building the robot.
First, we have the front frame. You attach the two motors onto the frame. Like this. And the other on the other side. Then, you have the back frame that should go into the three holes at the back of the motor.The performances of both prototypes were evaluated. In other words, it is the length of distance covered divided by the time it took to travel that distance.
However, it still requires a smooth surface to walk on.
Instead of three sensors, perhaps the configuration of five sensors being aligned in a semi circle shape might provide better line sensing capability for the robot.
Catch the Other Robot: This is a round track race with 2 robots. So, I'll put it back.
