Why are robots made to mimic humans actions? Isn't it better to make them better than Humans?

better you say ? That's a nice wheeled robot you have there. Can I borrow it for a day? Thanks. Wow, it's really fast, I cannot keep up with it walking or running on the street. Truly an amazing ...

Finding Center of Mass for Humanoid Robot

Yes. As @hauptmech mentioned, you can use your forward kinematics to get the center of mass of each link in the base frame. Then you can simply compute the weighted average of the masses and ...

What servos are suitable for a robot like Boston Dynamics’ Atlas?

The Boston Dynamics’ Atlas robot doesn't actually use servo motors. It uses electrically-powered hydraulic actuation. I saw a presentation by Boston Dynamics' Marc Raibert where (if I remember ...

What knowledge should I have if I want to establish a robotics company?

You need enough domain knowledge to be able to tell if someone is bullshitting you or not, to be able to determine when someone has an achievable or unachievable project idea, to be able to determine ...

How to balance a humanoid robot on one feet?

Humanoid robots balance and motion planning are not trivial tasks. I believe you will learn a lot if you read about Zero Moment Point (ZMP). Basically, it is a specific point of contact between the ...

Why there is so much research going on in humanoid robots?

From another point of view, bipeds(humanoids) are regardless of their use interesting since they are high dimensional nonlinear hybrid systems. Sure, there are more systems with those qualifications, ...

Humanoid robot arm - inverse kinematics - choose joint solutions

That looks like a fun pair of arms :-) Yes, if you already have a known pose, choosing a solution that minimizes movement is a decent choice. The obvious draw-back is that which choice is made for a ...

Humanoid balancing

They are two main approachs for humanoid robot walking. Practically it depends on the physical capabilities of your robot and what you want to achieve. If your robot is able to sustain strong impact ...

How can I calculate Center of mass for each link of Robot?

Since it is not sure that your robot is in a plane or not, I would consider it in 3D. You have all the geometrical dimensions of the robot. And I assume you have also all angles in all joints. You ...

Motion planning with sequential convex optimization

This isn't my area of expertise, but it looks like your guess in your question is correct. From the paper: Let $F_{\mbox{targ}}$ denote the target pose of the gripper, and let $F_{\mbox{cur}}(\...

Humanoid robot arm - inverse kinematics - choose joint solutions

You can use differential IK to solve for a set of IK solutions along a given trajectory. The idea is that you use the IK solution of the current time step, to compute an IK solution for the next time ...

How does a biped humanoid robot like OttoDIY move?

Unlike most bipeds, who walk by shifting their center of gravity towards the direction they want to move, the Otto DIY robot doesn't seem to have any clear shift in center of gravity. This is probably ...

How is whole body control different from computed torque control?

Whole body control (WBC) refers to how to control antropmorph structure (as a system), while the computed torque control (CTC) is a method to compute the torque in 1 single joint (i.e. to control 1 ...
