|Autonomous Technology research group
Research is organized and carried out in six fields of focus (research areas
with planned longer term goals). Practical research work is done in projects by
following a matrix organisation. Each field of focus includes usually several
on-going projects (planned actions with available funding). Research is lead by
professor Aarne Halme. The senior researchers usually act as project managers or
foremen of their group in addition to their own research work.
WorkPartner - Rolking centauroid service robot for
everyday outdoor tasks
- WorkPartner is a mobile service robot, which works
interactively with people. It is intended for everyday life tasks in outdoor
environment. Work is done by the aid of a human-like two hand manipulator.
The hybrid locomotion system allows motion with legs and/or wheels at the
same time. Tasks are learned and executed in close cooperation with the
The locomotion system allows motion with legs only, with legs and wheels
powered at the same time or with wheels only.
Passive vision fused with different types of ranging radars.
Navigation is fully automatic in locally mapping of ab unknown environment.
The robot learns to perform skilled tasks when working interactively with
Adaptive motion control system
The hybrid locomotion system provides rough terrain negotiating capability
and wide speed range at the same time.
The two arm manipulator is able to do humanlike tasks by manipulating
and/or using tools.

RoboBoat - The rowing robot
- RoboBoat - The rowing robot Automation Technology
Laboratory has constructed the world’s (probable) first robot that rows a
boat like a human rower. Rowing as a locomotion process is very close to
walking. The oars correspond legs with distinction that the body does not
take support on them but on the supporting media (water in this case).
There are many interesting topics to be studied with the rowing robot. For
example, there is evidence that oars as propelling devices are more energy
efficient than a propeller when the speed is moderate under the displacement
velocity. Power output of an average human rower is only 100-150 W and with
a standard small rowing boat a speed around 2 m/s (3,5-4 kn) can be
obtained. The same speed to power ratio is hard to obtain with any small
Roboticed rowing offers interesting possibilities to recover old rowing boat
cultures, like multi-oar Viking boats or big fishing boats, by assembling
several rowing robots on a same boat.
The test vehicle, shown in the picture, is a 4,0 m small standard rowing
boat. Weight without rowing mechanics, motors, batteries and control
hardware is about 70 kg. The total weight with all equipment is 210 kg. The
payload is still more than one person and the boat moves then with quite a
small propulsion force like 30-50N on calm water level below the
displacement velocity, which is about 1.9 m/s (3,7 kn). The propulsion
system of the rowing boat consists of two degree of freedom oars.
