Linear Actuator control of tracked robot

Help & Support Robot Parts

First post for me on RobotShop Forum. Youtube linked below shows a mini-bulldozer controlled by two levers. Each track has its own lever. Push forward and pull back to move forward or back. The force required is around 15 pounds each direction. Lever grip travel is about three inches both ways. I want to use RC to control the levers and eventually install a DC electric motor and batteries. So RC motor speed control is on my list. Riding this mini bulldozer (Struck Magnatrac MD1600) is torture due to abrupt movements in all directions, so RC is a must have. Dozer weighs in at 1,000 pounds. Any guidance on the best DC powered linear actuator, RC controller, and other opinions on this project are welcomed. Thank you.

It will all come up on how you are planning to mount the actuators to control the levers. Therefore, maximum stroke and force of the actuators will be important.
We do offer RC controlled linear actuators like the L12 Actuator 100mm 210:1 6V PLC/RC Control. However, the maximum force capabilities of these actuators won’t probably fit your application.
Our suggestion would be to go with more powerful linear actuators like the 4" Stroke Firgelli Automation 12VDC 35lb Force Linear Actuator w/ Pot Feedback with an appropriate DC Motor Driver RC controlled like the Actuonix Linear Actuator Control Board.
