Hi, i have calculated the time required for the cooking robot to flip an object as you can see from the attached file, however, the time result that i got was about 0.2 second which 's a bit small. So I'm wondering whether my calculating method is correct or not. Also, please note that i...

So an electrical motor converts electrical energy to mechanical one. But an electric motor can just produce a single motion in of itself. How come connecting a mechanical arm to it allows a diversity of movements like rotation, verticial and horizontal motions to both directions!?

Hi everyone! I am a mobile robot designer in autonomous space robotics. there is a great dilemma in front of me to opt a programming language for the robots between C++ and Java. the most important factor for me is performance of the language when i want to use it for applying very...

So, For FIRST FRC robotics, We have made 3 different objectives to research, and I decides to start with the projectile. We need to launch an 8" diameter foam basketball into a goal that's 18" diameter. We can be anywhere from 3feet to 54 feet away. We had an idea of using the classic...

Hello all! I have a question regarding how to get the linear and angular speed for this robot for example (RRP). http://img205.imageshack.us/img205/774/rrp.png I am given x and y or the hand, as well as theta (angle) If I were asked to calculate the linear. Do I derive x and y to...

Hey everyone, I want to make a a simplified "segway" project. I plan on using a servo motor with a wheel attached and attaching a breadboard to act as a inverted pendulum. My idea is to use LabVIEW to generate the PWM for the servo and (instead of using LabVIEW PID) use active filters to act...

Im supposed 2 design a robo like this 1, but here, the mechanical part seems more tought thn the electrical and programming. I couldn’t make out what mechanical structure is being used to have this type of motion. Can anyone please help. Here’s a start: There r 2 motors attached in the...

Hi, This is a problem I've been puzzling over and I can't get a straight understanding of it. I'm hoping someone can explain how conservation of momentum applies to this problem. Consider a planar 'robot' (ie 2 dimensional system) consisting of only 2 stiff limbs, connected at the 'hip'...

I am building a robot with a total mass of 835g, using two servo motors conected to the tires made of rubber which have a 3.33cm radius, and i wanted to know how to find out the total torque required to move the robot taking friction into account, the only things i know are...

look at the above image, the red coordinates is attached to the robot end-effector, and the other one is the base.coordinates. Now, As we know, the end-effector can do any rigid motion, so if a point P is attached on the robot end-effector. we can calculate the velocity of the point P. The...

I am positive when I was a kid some Candian guy, maybe from Alberta made robots without microchips. They seemed to have the ability to learn, adapt or mimic one of those types of behaviors. I think I read it in Reader's Digest say from 1990 - 95? Anyone remember anything about this? 1st...

We're trying to build a circuit that will detect when a laser crosses a photoresistor and light an LED. What we're trying to do is have three different photoresistors, and three diffferent LED's, each of which correspond to one photoresistor. The idea is that when one photoresistor is struck...

Hey guys, I was wondering if I could get a little info I'm building a robotic hand for a masters project. I'm interested in looking into actuating some of the joints using a 'dohelix' method, where a flexible plaited cord is twisted by a DC motor on one end to produce a translation on the...

Hi there, I was wondering if you could help me with a quick problem. I should probably know this but for some reason I am getting confused between different points of view: If I wanted to calculate the maximum torque required by a motor shaft to spin a mass at the end of a rod connected...

Is this a human or a robot? http://www.dumpert.nl/mediabase/1411301/5bd47efb/hee_kijk.html

High technology robots that big companies like Sony strut out are nice, but what I want to know is not how to make a robot as intelligent and motive as a human by brute force, but how to create a simple mobile creature, which can seek out the fuel it runs on, and re-energize itself, and the...

I am design a three jointed robotic arm that can lift 40 pounds. A diagram of the arm is attached. How can I calculate the torque needed at each motor to lift the 40 pounds?

I know this has been done on a larger scale but I was thinking of playing around with something simpler. My idea was to try to build a simple little robot that follows the point of a laser. It doesn't have to be elaborate: even if it just follows the laser around a few inches in front of it...

Hi all, i hope someone can help me out here. I have a rod (not massless) hanging like a pendulum. As its axis of rotation there's a motor that applies a constant torque. The rod will be rotated upwards, and then downwards to hit a ball like a golf club. Qn: Will a heavier rod or a lighter rod...

Im currently working on a project for a lawn mower robot and need some help with motor selection and mounting of the motors. We're not sure to go about using 2 motors out back and a free moving wheel up front, or 4 wheel drive. We estimate the robot to be about ~20 lbs or less, and our goal...
