Why Make Bipedal Robots?

A friend and colleague of mine who studies robotics says that bipedal robots present much greater challenges for stability and locomotion than those with more legs. So why is there so much effort to develop bipedal robots? Are there any practical…

Feedback controller: Is there any influence between outer and inner loop when running at different frequencies?

I've develop a quadrotor (only simulation on my PC using ROS) and the feedback controller resumes more or less the following structure: where you can think that process is the dynamic movement of the quadrotor (motion equations), the inner loop is…

How high of a gear ratio can a motor have?

I want to make a robot arm where a joint is powerful enough to lift 8 kg up at a distance of 1 meter. This requires torque $tau = r*F = r*m*g$ = about 80 nm. So now I am trying to find the requisite parts to put this together, i.e. motor + gears…

2D Robot Arm Inverse Kinematics with minimum joint loads

Suppose I have a robot arm with $n$ linkages of fixed length and equal density whose motion constrained within a 2D plane. I want the end effector to reach a particular pose $(x^*,y^*,\theta^*)$. I know that in general, there can be multiple…

Keeping two wheeled wall following robot straight

I have a two-wheeled (two DC motors) robot that needs to follow the wall beside the robot. The issue is that the DC motors spin at different rates (because they are not identical, of course), so the robot does not go straight when the same voltage…
