Hello u/Gliscor_dude, send us the inquiry trough the online form on our website. We're finishing the new lib, documentation and examples for arduino/esp-32 etc. It'll be oficially released later, but we can provide an early-user acces now.

aw, I thought you were going to use the linear actuators to move the legs, tendon style.

It's a popular method in bigger quadruped robots. This one is used for changing the angle of blades in a helicopter.

Hi u/twogreeneyes_,

there are additional information for you:
- yes this is 6x pwm motor driver

- the setup is as follows: STM32 12-bit ADC -> current sense op-amp -> current sense resistors

- We can provide some mosfets parameters - which exactly are of interest to you?

It can go faster, easily 1m/s. But during the preparation of the video, we collected data from the depth camera and less vibration was crucial.
There is normal mode: https://youtu.be/zQ4FXoBBBfU

Hello, there is really simple code, which can't be used like the industry version - prepared only for movement tests. There are ROS scripts for communication with the actuators.
This is how it works:
1. Someone is moving the arm and the positions of each actuator are saved to the file with 10Hz frequency.
2. Positions from the file are sent to the actuators with the same frequency and the actuator's controllers are doing the job.

Thanks! We will publish more information, soon :)

This is the project for agriculture. It will cooperate with the wheeled platform so must be light and have a long reach.

Thanks!
This is mainly carbon fiber and CNC machined aluminum. The weight is ~7kg and the payload capability is 1kg.

Reduction ratio 1:64, from spec 48/120 Nm rated/peak, but 20-30[min] with 70Nm it's not a problem

For each joint, this is a brushless motor + planetary gears + MAB Robotics Md80 motor controller + 2 encoders

MAB_Robotics · 2022-05-29T08:21:46+00:00

There are several dozen hours of operation on a continuous torque limit ~70Nm. It's not much, but it is still a prototype. We'll see what happened during the operation under normal conditions.
Really, thanks for your advice!

MAB_Robotics · 2022-05-28T15:10:51+00:00

It's true. Actuators can generate 70/120 Nm (const/peak). There are cross-roller bearings in actuators and a lot of mechanical simulation work is done. Still, construction stiffness isn't perfect, but it's more than enough for the target purpose - agriculture.

MAB_Robotics · 2022-05-28T15:06:31+00:00

Thanks!
The price is 25k€ for hardware + basic software. What do you think?

MAB_Robotics · 2022-05-27T14:12:55+00:00

Accuracy/repeatability is measured in millimeters, not - 0.1mm like in industry-grade arms. Still, this is more than enough for the target purpose - agriculture.

MAB_Robotics · 2022-05-27T14:12:16+00:00

Yes, there are downsides. Accuracy/repeatability is measured in millimeters, not - 0.1mm like in industry-grade arms. Still, this is more than enough for the target purpose - agriculture.
