Other Essential Skills:

Working with Others

Robotics technicians and technologists in large companies usually work as part of a team that may include engineers, other technicians and technologists, sales, production, and tradespeople (electricians, machinists, plumbers, welders). The size of the team depends on the size of the company and the size of the project. Each member of the team is assigned tasks, but team members often work collaboratively to solve problems. They may work alone to maintain and repair equipment, but often work with the client's staff, such as millwrights and electricians. Robotics technicians and technologists with more experience or seniority may assign tasks to other workers or take a more senior role on the team.

Continuous Learning

Robotics technicians and technologists are responsible for setting their own learning goals. They access online information, forums and blogs to stay up to date with trends, and evolving technology. The field is highly competitive and technology is always changing. They learn on the job and attend training offered in the workplace, such as "lunch and learns" on new and updated products. They take courses on topics such as PLC programming, and attend conferences and workshops. They may decide to complete a degree in engineering. Some companies encourage and support further training. They may or may not belong to professional associations, such as Applied Science Technologists & Technicians of British Columbia (ASTTBC).
