00:00:00.100 --> 00:00:04.360
This is Reach a saved two joint bench arm project in BotSims

00:00:04.360 --> 00:00:08.525
Open the tutorial project and confirm replacement only after saving your current

work The anchored base supports a shoulder upper arm elbow forearm and

gripper layout This walkthrough uses real workbench captures and an editable project

5
00:00:18.140 --> 00:00:19.740
you can download

6
00:00:19.840 --> 00:00:24.575
In Assembly inspect the attachment tree The upper arm follows the shoulder

7
00:00:24.575 --> 00:00:28.965
and the forearm follows the elbow That hierarchy determines which links move

8
00:00:28.965 --> 00:00:32.940
when a servo target changes Select a component to read its mass

9
00:00:32.940 --> 00:00:38.175
and parameters Orbit and pan to check clearances Group isolation helps you

10
00:00:38.175 --> 00:00:42.120
concentrate on the mechanism without losing the rest of the project

11
00:00:42.220 --> 00:00:46.350
In Wiring trace the battery into the regulator Both servos share a

12
00:00:46.350 --> 00:00:51.325
supported five volt supply and ground The controller uses independent named servo

13
00:00:51.325 --> 00:00:56.695
channels for shoulder and elbow commands These channels are virtual aliases They

14
00:00:56.695 --> 00:01:01.045
do not certify a specific board's pin mapping current capacity or peripheral

15
00:01:01.045 --> 00:01:07.245
configuration Review warnings and verify the real component datasheets before building hardware

16
00:01:07.345 --> 00:01:11.910
Open Code The program commands a small sinusoidal shoulder and elbow sweep

17
00:01:11.910 --> 00:01:17.460
and logs approach reach and return stages Targets are angles in radians

18
00:01:17.460 --> 00:01:20.945
The program keeps wheel drive at zero and stops issuing arm targets

19
00:01:20.945 --> 00:01:24.645
if power is unavailable Change one amplitude at a time so that

20
00:01:24.645 --> 00:01:26.950
the result stays understandable

21
00:01:27.050 --> 00:01:30.175
Press Run and watch the links move in Assembly This is a

pose Use the preview to study structure and control logic and use

26
00:01:49.420 --> 00:01:52.995
a suitable dynamics tool for those additional questions

27
00:01:53.095 --> 00:01:57.880
Pause inspect the final state and export the project The saved tutorial

28
00:01:57.880 --> 00:02:02.560
JSON includes the full assembly wiring and controller so you can reopen

29
00:02:02.560 --> 00:02:07.160
and revise it later The documentation provides this video captions and a

30
00:02:07.160 --> 00:02:11.065
transcript You now have a second kind of robot project with a

31
00:02:11.065 --> 00:02:14.675
different and explicitly documented simulation scope
