shaiqbashir Posted December 27, 2006 Report Share Posted December 27, 2006 Hi Guys! Hope u would be fine out there! Well! im planning to make a robot. The drive mechanism that i have choosen for that robot is a Tri-Cyclic mechanism. That is two Big Wheels at the back, both of them will be connected with one single motor. SO there will be one motor driving two back wheels. Just like in a car. There will be a third wheel in the front portion of the robot that will be used for steering purposes. Now i want to ask you that what are the known issues and problems with this type of drive mechanism? WHat motor should i use for steering? Should it be Servo or a Stepper? Is the steering motor needs to be powerful enough?? What could be different problems i can face in this mechanism? Please tell me as soon as possible! Take carez! Good BYe!

audioguru Posted December 27, 2006 Report Share Posted December 27, 2006 Hi Shaiq,Let the robot do a wheely then you don't need to steer it. ;DMy car has front-wheel-drive. When it snows here in winter then the cars with old-fashioned rear-wheel-drive don't go anywhere because their back wheels don't have much weight on them so they spin on the snow and ice.This winter has odd weather because it is not cold, the grass is green and no cars are skidding.HEY! It is snowing a little. Quote Link to comment Share on other sites More sharing options...
ante Posted December 28, 2006 Report Share Posted December 28, 2006 Why not put one motor on each back wheel and let the front wheel swivel? This way it’s very simple to steer the thing! Quote Link to comment Share on other sites More sharing options...
