TM4C1294 IoT Servo Drive Finished! Kickstarter Online!

Hello Chris,

Excellent project and product....

Hello Chris,

By the way, what is the power requirement of the entire assembly and how are you providing the power in the existing setup?

Hi :)

We can run our motor from 12 to 24V. Maximum is about 30 Wats the drv is very efficient but still there is not much space for effective cooling at the PCB. But this is still far enough for a NEMA17 Stepper.

We have a power plug next to the Ethernet plug. There are 6 Wires, two for Power and 4 for GPIO or CAN or UART. We have made test setups with cheap wall supplies, batteries and laboratory supplies.

Cheers,

Chris

Hello Chris,

I would have suggested using PoE stage for power. That would have made the assembly requiring on the Ethernet connector for both power and control-communication, instead of adding wall connectors.

Yes, we had a look at PoE. But there is not enough space for it :(. PoE would have been great!

Looks nice, I do have one question.

I can see a use for Ethernet, although I'd want CAN myself. However, what value do you see in IoT for this?

Hello Chris,

What is the size of the PCB? And is that a requirement?

It is just easy to use. We do not attach our motors to the internet, we have a local network so far. You don't need any device drivers or cable adapters just plug in, navigate to the motors IP Adress and start.
Im Matlab you only need 3 Lines of code to command a new target position or torque to the Motor. It is ready in seconds.

around 36 X 36 mm :). The Ethernet plug it self already needs a third of it... Yes it is a requirement we have to fit at the back of a Nema17 Motor.

Hello Chris,

Which part of the robot hosts the IoT motor. Also I checked with one of my colleagues, and he did mention that it is possible to do two stack board solutions, one hosting the power stage and one hosting the ethernet connection.

Hi Chris,
Cool little machine you made.
I can imagine a CNC router being commanded over the cloud when say a 5 axis mill requires factory support from remote locations. The servo motor is often at the cutter head though XYZ axis are all stepper movements.

All Motors are commanded by my windows PC. The program is written in c# and calculating the inverse kinematic in 1KHz. My program is commanding all the motors over TCP (not realtime).
