I haven't done an update for a while
most of the activity with Robbie has been
trying different parts and arm designs
between Hector and Inmoov as always there
are pros and con to each design. Inmoov
has more activate development so the larger
part of Robbie is Inmoov. The main
problem with the Inmoov design was the lack of
shoulder pan joint ROS moveit needs
some form of pan joint for the kinematic solvers
to find a solution after trying
different joint configuration Inmoov with the waist pan
joint worked just as good as Hector.
Hectors biggest down fall was the gearbox the
worms slipped under heavy loads and the
back lash was very high. I still have 2 of
these gearboxes in the elbows so i will have to fix that at some point
On the software side I have made large
improvements in localisation and navigation
Robbie's ability to go through door
ways has improved to the point where navigation to
any place in the house is possible.
Using behaviour trees he constantly monitors the
battery if the battery is low he auto
docks with the charger and will continue with the task
after charging is complete.
Robbie's arms are controller by a
Adruino Due the pull up resistors need to be disabled
To mark the change from hardware
testing back to robot development I have changed the colour
scheme to black and gold. I dont intend
to change the design but rather improve what I have
The focus will be more on software and
operational use
Interesting color theme. I'm glad also to see that almost all parts are now from InMoov besides the elbows. I would love to see a video of the robot evolving on its own in the environment..
ReplyDeleteThank You Gael this marks the end of stage 1
DeleteStage 2 is gaining trust of the robot allowing him to stay on with all systems running and roaming around the garage at first then the house. the last couple of weeks has been interesting i will be doing a lot more blogging and video
I have added your InMoov Robbie to my picture collection of full robots.
