Providing Stability and Mobility for Collaborative Robots
By Heather Lanphear, Web Designer, LTW Ergonomic Solutions
is their lack of mobility. Now LTW has created a height-adjustable, tilt- ing table that serves as a base for cobots. CoBase™ is a patented indus- trial table with options for a tilting tabletop, an inverse cobot mount, cobot cart, and more. Some cobots, such as those from
O
Universal Robots (UR), are so user- friendly that no knowledge of coding is required to create and run a pro- gram. Unlike room-sized, heavy au- tomation, lightweight and flexible UR cobots can be used alongside hu- mans with no safety guards. Force- sensing technology enables the robot to stop operating if it encounters ob- stacles in its path. Cobot companies
ne challenge to using collabo- rative robots, also known as cobots, in daily manufacturing
compete to make the most collabora- tive robot on the market, but a robot is only as collaborative as its base.
Tilting Cobot Table LTW’s solution, the E4H tilt
cobot table, or CoBase, is height-ad- justable with four electric actuators. While cobots may come in fixed sizes, workers’ heights can vary dramati- cally in the workplace. In order for a cobot to be truly user-friendly, work- ing with and programming it should be tailored to the user’s height to pre- vent back pain and musculoskeletal disorders (MSDs). With just the touch of a button, the base raises and lowers.
The table’s height-adjustability can also raise a cobot’s level of use-
fulness. While some companies have just one dedicated purpose for each of their cobots, other companies move cobots to different applications when needed. Different applications may come with different heights: the CoBase may need to be one height for CNC tending and a differ- ent height for pick-and- place operations. The CoBase can be wheeled to where it is needed, adjusted and reprogrammed easily. To make cobots even
more user-oriented, CoBas- es can be made with tilting tabletops. Instead of look- ing straight down at a tabletop for work all day, users can tilt their work to an angle that is more com- fortable, improving their posture. This can also ex- pand the cobot’s usability by adjusting its reach with the tabletop angle for cus- tom projects. The CoBase is de-
ries. The CR-E4H is a non-tilting version of the original height-ad- justable E4H tilt cobot table. Both of these CoBase models can come in in- verted versions where the cobot is mounted upside-down above the tabletop.

signed to be a complete solution with easy set up and to provide a place for every part of the cobot. The cobot mo- tor and controls are kept safe and out of the way with the under-tabletop mount. Cord management is simpli- fied with included cord wraps and winders that keep the CoBase work- space neat and organized. Aside from attaching the cobot
to its custom tabletop bolt pattern, no tools are needed for set up. Users can start programming the mounted cobot within minutes. Cobots are portable around plants with the CoBase’s locking swivel casters. Cobot systems can be quickly moved between tasks and areas to run dif- ferent cobot programs without wast- ing time mounting cobots onto differ- ent tables or surfaces. LTW offers custom tabletops,

such as aluminum, steel, maple block, laminated, and ESD laminat- ed (anti-static). CoBases can be painted with company colors to match the rest of the workplace. Oth- er options include electrical box mounts and forklift tubes.
Table Variations LTW is developing more Co -
Base models, including non-height- adjustable, inverted and cart ver- sions. The CR-GB (collaborative ro- bot — general base) has a static height with no actuators and has the lightest price tag in the CoBase se-
Height-adjustable E4H tilt cobot table. The CR-E1 cart is modeled after
LTW’s height-adjustable material handling E1 cart and enables users to wheel their cobots to different fix- tures around the plant, securely dock the cart to the fixture and run a pro- gram — all without the cobot having to leave the cart. The CR-E1 cart adds flexibility
for companies that want to use their cobots actively in multiple areas of their businesses without wasting time re-bolting cobots to different surfaces.
Every cobot can be used on a
CoBase, regardless of brand or mod- el. Each CoBase is designed with a custom bolt pattern specific to the cobot or robot being used. If a compa- ny upgrades to a new cobot with dif- ferent bolt pattern, the tabletop can be replaced by LTW with a corre- sponding tabletop bolt pattern for the new cobot. If a company ever chooses to
stop using cobots, the CoBase can still be used as an industrial height- adjustable, tilting table, which also makes for a great welding or assem- bly table. This dependable solution can be used for a variety of applica- tions and is designed to be used with
any current and future cobots. Contact: LTW Ergonomic
