Inject node has the option to repeat injects. However, the minimum time is 1sec.  
I would like to poll my robot for telemetry data every 100ms.

Is this possible?

It worked for me.  
See the following flow:

```auto
[{"id":"42d15146d49d38a5","type":"inject","z":"89b8979d.98af88","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"0.1","crontab":"","once":false,"onceDelay":0.1,"topic":"","payloadType":"date","x":400,"y":100,"wires":[["21a0dd61478dd4f3"]]},{"id":"21a0dd61478dd4f3","type":"debug","z":"89b8979d.98af88","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":600,"y":100,"wires":[]}]
