Units for Command functions (position, velocity, effort)

The HEBI documentation shows "rad" or "m" as units for position command and "rad/s" or "m/s" for velocity command. The units "m" and "m/s" are confusing me as X series actuators are limited to angular position and angular velocity.

Re: Difference between hardware_receive_time and receive time

How can we set feedback frequency of our own by that I mean suppose I want HEBI to act in 0.01s or 0.001s? with 100Hz or 1kHz. Also that difference between (receive_time - transmit_time) does not give us the time duration in which the whole process falls? And the control frequency is perfectly perio...

Re: Difference between hardware_receive_time and receive time

Thanks for the answer. In our controlling if we set before
group.feedback_frequency = x

thn receive_time - transmit_time should be theoretically equal to 1/x right?

Difference between hardware_receive_time and receive time

I have a doubt related to the two feedback parameters. What is the difference between hardware_receive_time and receive_time and the same is the case with the trasmit_time and hardware_transmit_time. A thing that is confusing in the document is local or remote in the explanation of both the terms. P...

HEBI (I/O) board getting feedback from analog/digital in python

My query is related to accessing I/O board analog and digital inputs in python. I found this link but still was not able to access them in python https://docs.hebi.us/hardware.html#io-board-feedback I believe it should be accessible something like that fbk = hebi.GroupFeedback(group.size) a = fbk.a1...

Command Strategy in Python Script

My query is related to control modes. If I try to give command of control strategy in python script, the actuator always stops working but it runs fine when I give command from scope with the same control strategy. Like I give command group_command=hebi.GroupCommand(group.size) group_command.control...

Error in code for ex_kinematics_visualization.m

I am using a 6Dof arm.

When I run the code from example, I am receiving this error

Error using setupArm
Too many input arguments.

Error in ex_gravity_compensation (line 25)
[ arm, params ] = setupArm( armName, armFamily, hasGasSpring );
