APi start and stop implemented but doesnt seem to work, at least not on jaco base without arm
only upload urdf with jaco_description.launch
renamed root to jaco_base_link
tried to fix joints limit, test this!!! can be savely reverted if not working
temporarily switched to /jaco_arm/arm_controller (simple jaco api controller) because velocity controller doesn't work under high load
changed order of jaco start_everything
Improved gripper controller
refactoring
added arm_standalone launch
Merged latest devel stuff from github
Merge branch 'api_control' into develop
