The prototype designed is primarily a caterpillar type and can be interchangeable to wheeled configuration. Graphite brushed motor is used in the development with a tracked belt transmission. Double sided timer belts are used as tracks. These tracks are guided by flanged timing pulleys.
mobile robot (OMR) was proposed for explosive detection capability
with autonomous navigation on rough terrain. It has a four-wheel
drive system with tracked configuration. The four separate drive
constructed by means of a motor, bevel gears, sprocket-chain and
wheels. The drive unit drives the ground wheel by means of a roller
chain. The whole load of the system is distributed on three ground
