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...

Homework Statement What formula or formulas are used to calculate the distance traveled by the robot given the radius of its wheel/tire (R) and the degrees through which the motors rotated (d)? Use n to represent the number of rotations made by the motors. Show all steps and formula(s)...

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...

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...

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

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...

Hello! Well I am in second year Engineering Physics and we're building a robot this summer. We have four students in my team including myself. We're to build a robot that follows a loop of black tape on a track, and race with other robots. I have a few questions: 1. We decided to use...

Homework Statement I am building a balancing robot like the one here: http://www.geology.smu.edu/~dpa-www/robo/nbot/ It's basically a body mounted on two wheels and its purpose is to control the motors as to keep the wheels under the center of mass and therefore keep the body in an upward...

I'm working on a robot for my final project in class. It's your basic line following deal. It has 5 sensors that face the floor on the front and it just follows a track made of black tape. I'm just going to use this one thread for all my issues. Current issue: I don't get a certain type of...

I need to make a basic robot (two wheels, two motors, etc.) follow me or a sensor, that will be attached to me. How would I do this? For example, I can have an IR Emitter on me and like two IR sensors on the robot; one that controls the left motor and one controls the right motor. I don't have...

Hi guys, I'm doing a robotics project that requires me to compensate for the bending of the arm due to an end weight. I can calculate the deflection at the end of the arm for a given weight e.g. End link horizontal (90 degrees), end weight = 1000g, deflection = 10mm From this i can calculate...
